Installation
2 Installation
This section focuses on the installation of the following elements of an APACS+™ PROFIBUS system:
•
An APACS+ Fieldbus Module (PFM) and its associated transition board
•
A Siemens PROFIBUS PCI interface card (CP 5611) installed in a PC or a Siemens PCMIA interface
card (CP 5511) installed in a PC laptop
•
Cabling between these components and other elements of the PROFIBUS system.
These installation instructions assume that the following components are already installed and in place:
•
An APACS+ controller, backplane, mounting rack, power supply, and enclosure
•
A PC workstation with an M-Bus adaptor for development, storage, and downloading custom
applications to an APACS+ controller
The APACS+ system and module rack must be available before the PFM and its transition board are
installed. Other network components must be available before cabling and software configuration.
Installation of the APACS+ PFM network includes several major steps. The order of installation is
flexible, with hardware installation preceding cabling:
•
Installation and cabling of the PFM transition board, then the PFM module
•
Installation and cabling of the Siemens PROFIBUS PC card or laptop PCMCIA interface, including a
one-time installation of a Windows control panel applet that sets up the interface.
•
Installation and cabling of an optional PROFIBUS DP-to-PA link or link/coupler
•
Installation and cabling of PROFIBUS field devices
After the APACS+ PFM network hardware is installed, a set of software configuration tools and
programs prepare the network for data acquisition and control.
Review and complete the preparatory steps in subsection 2.1 before proceeding with the installation.
IMPORTANT
The PFM installation should be in accordance with the National
Electrical Code (NEC), other applicable construction, and electrical
codes.
The PFM is only to be used for the purposes described by Siemens.

2.1 PFM Identification, Delivery, and Handling
2.1.1
PFM Module Identification
The PFM module is identified by the letters “PFM” on its bezel and by two nameplate labels. One
nameplate label is large, similar to the one shown in Figure 2–1, located on the left side of the module. A
smaller label is located inside the bezel compartment. Both labels contain the model designation, part
number/issue level, software version number, and serial number (S/N). The larger label also lists the
power requirements, and space is provided for information such as safety agency certifications and
special precautions. The following is typical:

2.1.3
Installation
Environmental Considerations
Many industrial environments create severe operating conditions. The conditions where the PFM is
located must be within the specifications stated in section 6.2.
To ensure reliable data communications, it is prudent to locate PFM hardware away from sources of
interference, such as high-current electrical equipment that emits strong electromagnetic fields and
switching transients.
High-power EMI-producing equipment should not be connected to any power lines dedicated to PFM
signal channels.
2.1.4
Equipment Delivery, Return, and Handling
The following subsections provide information of interest to shipping, receiving, and warehouse
personnel.
2.1.4.1 Predelivery Test
Each PFM is fully tested and inspected to ensure proper operation. If the module is ordered
factory-installed in a MODULPAC enclosure or other cabinet, the module is tested as part of the system
and inspected to ensure proper operation.
2.1.4.2 Factory Shipment
Each PFM is enclosed in a static shielding bag and packaged for shipment. Accessories are packaged
separately. If a PFM is ordered factory-installed in a rack housed in a MODULPAC enclosure or other
cabinet, the enclosure is bolted to a pallet and wrapped for protection during shipment.
2.1.5
Return of Equipment within North America
US Customers:
•
Call the Repair Order PAS Inside Sales/Order Management Group at (215) 646-7400, ext 4RMA
(4762) weekdays between 8:00 a.m. and 4:45 p.m. eastern time to obtain an RMA number. Mark the
RMA number prominently on the outside of the shipment.
•
When calling for an RMA number, provide the reason for the return. If returning equipment for
repair, a detailed description of failure symptoms and system behavior will be requested. Supply a
purchase order number for repairs. Follow the TSC specialist's recommendation for battery

•
If applicable, you must supply a Material Safety Data Sheet (MSDS) with each item being returned if
it was stored or used in a location where hazardous materials were present.
•
Package items to be returned in their original shipping containers. Otherwise, package it for safe
shipment or contact the factory for shipping recommendations. A module must be placed inside a
static shielding bag to protect it from electrostatic discharge.
Canadian customers:
Contact Siemens Canada.
2.1.6
Return of Equipment outside North America
Contact your Siemens Representative.
2.1.6.1 Equipment Handling and Storage
The PFM is completely enclosed and can be safely handled without undertaking special ESD
(electrostatic discharge) handling procedures provided the bezel compartment door is closed and secured.
DO NOT touch the connector pins on the back of the module. Handle the module carefully and do not
subject it to excessive shock or vibration.
The storage temperature and humidity parameters listed in section 6 must be met for storage of a PFM.
2.2 PFM Installation
The PFM module plugs into the backplane of the APACS+ system and into a connector on the transition
board assembly. Before installing the PFM into a module track, secure the PFM transition board to the
local termination panel.
2.2.1

Keying the PFM Module and Rack
APACS+ Modules are shipped individually packaged in protective, sealed, static shielding bags. Refer to
subsection 2.1.5 for module handling considerations.
Each APACS+ slot and each module can be keyed to prevent accidental installation of a module into an
incompatible slot, which may impair system performance. Module and rack keying is highly
recommended; see Figure 2–3.
Modules are keyed at the factory. The keying pattern is unique to each module type (e.g. PFM, ACM,
CAM, CDI, CDO-DC).

Installation
SD39PFM-1
A factory-assembled rack is keyed at the factory. If you are assembling the rack on site, you must key
each slot according to the module type assigned to it. The slot keying pattern complements the module’s
keying pattern. Stop plugs are supplied with the rack.
Before adding a module to a rack, be sure to key its slot.

top and bottom rails.
3. Press the stop plugs into the appropriate key holes of the top and bottom rails as identified by the
solid dot keying patterns in the figure.
2.2.3
Module Installation
1. Where applicable, refer to your system documentation and note the assigned rack and slot numbers
for the module to be installed.
2. Remove the PFM module from its static-shielding bag and ensure that the module’s bezel is keyed.
Also, check the rack slot assigned to the module to be sure it is keyed. If required, refer to subsection
2.2.2 for rack keying information.
3. Insert the module in its assigned slot in the rack. Use uniform pressure to firmly seat the rear of the
module in the rack’s backplane and transition board connectors. If the module does not seat properly,
check its keying pattern. A properly seated module has the rear of its bezel flush against the rack’s
front rails. A keyed module that is not matched to a slot does not engage the backplane or transition
board connectors or seat flush against the rack’s front rails.
4. As shown in Figure 2–3, pivot open the bezel’s pivoting top and bottom handles to expose the slotted
captive mounting screws then secure the module to the top and bottom rails. Close the bezel’s handles
when finished.
CAUTION
Do not use the captive mounting screws in the bezel to seat the module.
Damage to the bezel can result. Properly seat the module before
tightening the captive screws.

DP Wiring Guidelines
PROFIBUS-DP uses RS 485 communications protocol, (often referred to as H2).
•
The RS 485 transmission technology is easy to handle, and installation of the twisted pair cable does
not require expert knowledge. All devices are connected in a bus structure (multi-drop configuration)
with up to 32 stations (master or slaves) connected per segment.
•
A DP network can contain a maximum of 126 devices. When more than 32 stations are used,
repeaters (line amplifiers) must be used to connect the individual bus segments.
September 2005
2-9
Installation
SD39PFM-1
•
This bus (multi-drop) structure permits addition and removal of stations, as well as step-by-step
commissioning of the system without influencing the other stations. Later expansions have no effect
on stations already in operation.
•
An active bus terminator at the beginning and end of each segment terminates the bus. To ensure
error-free operation, the bus terminations must be enabled at each end of the segment. Siemens and
other vendors have switchable bus terminators designed into their devices or plug connectors.
Various well-known manufacturers offer PROFIBUS cable and plug connectors (See the PROFIBUS
product guide for company names and addresses).
•
When connecting the stations, make sure that the 2 wires are connected with correct polarity. The red
wire is for signal B (pin3 - TXD/RXD-positive), and the green wire is for signal A (pin 8 TXD/RXD-negative).
•
The shield braiding and, if present, the shield foil should be connected to protective ground at both
ends of the cable with good conductivity via shield clamps covering as large an area as possible. If a
potential difference occurs between the grounding points, an equalization current can flow through a
shield connected at both ends. In this case, install an additional potential equalization line.
•
It is recommended that the data lines be kept separate from all high-voltage cables.
2.4.3
Considerations for Baud Rates >1.5Mbaud
•
Baud rates greater than 1.5 MBaud require the use of special connectors. These connectors (and some
devices) have built in Inductors, which are necessary in order to run with higher baud rates (as stated
in the PROFIBUS guidelines).
•
Spurs or stub lines should be avoided for data transmission speeds of more than 500 kbaud, and are
not allowed when using baud rates greater than 1.5 Mbaud. Plug connectors are available that permit
the incoming data cable and the outgoing data cable to be connected directly into the plug connector.
This type of connector eliminates stub lines, and also allows stations to be connected and
disconnected without interrupting data communication with the other stations.
•
12 MBaud installations require a minimum cable length between two stations of 1m/ 3feet.
A detailed installation guideline is also available from the PROFIBUS Trade Organization (PTO): PTO

DP Segment, Speed, Distance Constraints
Transmission speeds (frequencies) between 9.6 kbaud and 12 Mbaud can be selected. One unique
transmission speed is selected for all devices on the bus at the time of system commissioning based
on the devices connected, and the length of the PROFIBUS DP network. The following table shows

2.5 PROFIBUS PA Installation and Cabling
PROFIBUS-PA uses the extended PROFIBUS-DP protocol for data transmission. In addition, the PA
profile, which defines behavior of the field devices, is used. Transmission technology, in accordance with
IEC 1158-2, permits intrinsic safety and also allows the field devices to be powered over the bus.
PROFIBUS-PA devices can be easily integrated in PROFIBUS-DP networks using a segment coupler.
2.5.1
IEC 1158-2 Transmission for PA
Transmission technology in accordance with IEC 1158-2 meets the requirements of the chemicals and
petrochemicals industries. It permits intrinsic safety and allows the field devices to be powered over the
bus. This technology is a bit-synchronous protocol with continuous current-free transmission. It is often
referred to as H1. IEC 1158-2 technology is used by PROFIBUS-PA. Transmission is based on the
following principles:
•
Each segment has only one source of power, the power supply unit.
•
No power is fed to the bus when a station is sending.
•
Every field device consumes a constant basic current at steady-state.
•
The field devices act as passive current sinks.
•
The passive line termination is performed at both ends of the main bus line.
•
Linear, tree and star networks are allowed.
•
To increase reliability, redundant bus segments can be designed.
For modulation it is assumed that a basic current of at least 10 mA is required by each bus station to
supply the device. Communication signals are generated by the sending device by modulation from +/- 9
mA to the basic current.
2.5.2
Installation Hints for IEC-1158 Transmission
Usually located in a control room are the process control system, operator control and monitoring devices,
and the segment coupler implementing the linking of bus segments with IEC 1158-2 technology (PA) to
segments with RS 485 transmission (DP). Segment couplers adapt the RS 485 signals to the IEC 1158-2
signals. They provide the current for the remote powering of the field devices. The power supply unit
limits current and voltage on the IEC 1158-2 segment.

Installation
SD39PFM-1
A combination of tree and line structures permits optimization of the bus length and adjustment to
existing system requirements. Maximum permissible stub line lengths must be considered. A two-wire
cable (shielded or unshielded) is used as the transmission medium. It is recommend that you use the
reference cable specified in the Table 2–4. Other cables with larger conductor areas are also possible. For
details refer to the installation guidelines for PROFIBUS-PA from the PROFIBUS Trade Organization
(PTO). The order number is 2.092.
Both ends of the main bus cable are equipped with a passive line terminator which consists of an RC
element switched in series with R=100 Ohms and C=1 µF. When a bus station is connected with its poles
reversed, this has no effect on the functionality of the bus. It is recommend that devices be equipped with
automatic polarity recognition. The devices then operate correctly no matter what the assignment of input
terminals to the data signals is.
The number of stations which can be connected in one segment is limited to 32. This number is further
restricted by the type of explosion protection class selected and any powering over the bus. When
intrinsically safe networks are operated, both the maximum supply voltage and the maximum supply
current are specified within clearly defined limits. Even when intrinsically safety is not required, the
power of the remote power supply unit is limited.
2.5.3
External Power Supply
Connection of bus-powered devices and externally-powered devices on an intrinsically safe bus is
permitted if the externally-powered devices are equipped with appropriate isolation in accordance with
EN 50 020.
2.5.4
Fiber Optic Transmission
Fiber optic conductors can be used for PROFIBUS for applications in environments with very high
electromagnetic interference and to increase the maximum distance for high transmission speeds. Two
types of conductors are available: inexpensive plastic fiber conductors for distances greater than 50 m or
glass fiber conductors for distances greater than km.
Siemens and other vendors offer special bus plug connectors with integrated conversion of RS 485 signals
to fiber optic conductors and vice versa. This provides a very simple method of switching between RS
485 transmission and fiber optic transmission within one system. See PROFIBUS guideline 2.022 for the
specification of the PROFIBUS-FO transmission technique. An overview of the fiber optic components
which are available can be found in the PROFIBUS product guide.

2.7 GSD Files
Manufacturers of PROFIBUS devices supply devices characteristics in structured ASCII text files
generically known as “GSD” files. These files generally have .gsd filename extensions, hence the name,
although they may also have .gse extensions, where e indicates English. Device characteristics listed in
GSD files include vendor identification, supported baud rates, timing specifications, features, and I/O
signals. GSD files are freely available from manufacturers and are usually supplied on diskette or CD and
shipped with the devices they encompass. GSD files may also be downloaded from manufacturer’s web
sites. A device-specific GSD file is required for every device installed on a PROFIBUS.
Configuration software runs on the PC or laptop with the CP 5611 interface card installed. The software
expects to find GSD files in the following directory of that PC or laptop:
X:\SIEMENS\CPBV50\GSD, where X represents a drive designation.
Before attempting to install a PROFIBUS device, ensure that its GSD file exists in the correct directory.
2.8 Preparing the PROFIBUS DP Configuration Workstation
Siemens provides interfaces that connect a PC or laptop to a PROFIBUS DP bus. The PC interface is a
CP 5611 PCI card. The laptop interface is a CP 5511 PCMCIA card. After these interfaces are installed
and set up properly, they are functional equivalents. The installation and setup procedures differ slightly.

but not both places. It is not possible to copy the authorization by copying the diskette or the hard disk
drive.
To manage authorization, the program AuthorsW.exe on the diskette does the following:
•
Displays the available Simatic licenses on local disks of the workstation or laptop from which
AuthorsW.exe has been run
•
Installs licensing from the diskette to a hard disk drive
•
Returns licensing from hard disk drive to the diskette

Setting the PG/PC Interface through its Control Panel Applet
The PC/PC interface begins with the CP 5611 Interface card installed in a workstation or a CP 5511
installed in a laptop. These cards connect the workstation or laptop directly to the PROFIBUS DP
network and indirectly to PA devices through intermediaries. The card enables the COM PROFIBUS and
PDM programs running on the workstation to communicate with PROFIBUS masters and slaves. The
proper setting for the card differs for COM PROFIBUS and Simatic PDM, but these programs select the

3 Configuration
A set of software tools creates an interface between an APACS+ controller, a PROFIBUS Fieldbus
Module (PFM), and a PROFIBUS network.
The purpose of this interface is to integrate PROFIBUS field I/O devices seamlessly into a Siemens 4mation software environment. Applications running in this environment may rely solely on PROFIBUS
devices for field I/O, or they may include a mix of PROFIBUS devices and devices connected to the
extensive line of analog and discrete I/O modules provided by Siemens.
Siemens configuration software, installed through procedures listed in Section 2.0, consists of the
following:
•
Set PG/PC Interface a control panel applet for configuring a Siemens CP 5611 or 5511 interface card
and establishing PROFIBUS DP bus characteristics
•
COM PROFIBUS, for configuring devices on a DP bus
•
Lifelist, a special-purpose program for identifying, discovering, and documenting DP and PA devices
•
PDM, a program for setting parameters of DP/PA devices and monitoring or simulating I/O
An APACS+ PROFIBUS network consists of these elements:
•
An engineering workstation for developing and monitoring the Siemens 4-mation application that
runs on the APACS+ controller. This workstation includes a Siemens Modulbus interface card,
connected to the APACS+ system containing the PFM module.
•
A second PC workstation or laptop with a Siemens PCI CP 5611 interface card or a PCMCIA CP
5511 interface. This workstation or laptop provides a hardware platform for PROFIBUS
configuration tools that configure the PFM and PROFIBUS slave devices.
•
An optional PROFIBUS DP/PA link/coupler, which provide the hardware and software interface
between the PFM and PROFIBUS PA devices.
•
PROFIBUS DP and PA field devices from Siemens and other manufacturers.
NOTE
Configuring a PROFIBUS network for use in an APACS+ environment
requires only a small fraction of the functions available in the
configuration programs COM PROFIBUS and PDM. The instructions in
this manual make no attempt to describe features that are not applicable
to an APACS+ environment. Do not change settings or selections unless
you are specifically told to do so or unless you possess expert knowledge
and fully understand the implications of your actions.

SD39PFM-1
The procedures in this section do not explicitly remind you to save your work to hard disk or to back
them up on removable media although it is obviously prudent to do so. Configuration developed in COM
PROFIBUS and PDM are saved automatically, but you must explicitly save incremental versions of your
configurations under different files names if you wish to revisit them.
3.1 Populating the PROFIBUS DP Network with COM PROFIBUS
Identifying and configuring DP devices with COM PROFIBUS is an iterative process, repeated until all
the devices are installed on the DP network. It is possible to interrupt the process, save the incremental
version as a file, and return later, building on previous effort. It is not unusual to run the program
repeatedly as you systematically add devices to the network.
If you already have an active DP configuration loaded into a master, you can import it into COM
PROFIBUS from the master and load it into a new configuration. See subsection 3.5. You might elect to
do this if you already have a working network and wish to add devices to it.
1. From the PC with the CP 5611 (or laptop with CP 5511) installed, run COM PROFIBUS. Select
Start > Programs > Siemens COM PROFIBUS V 5.1 > COM PROFIBUS V 5.1.
The program displays a new, blank network, with a single purple line representing the PROFIBUS
DP bus.

2. Populate the PROFIBUS DP network by expanding the DP Master and DP Slave lists in the left pane,
also know as the “Hardware Catalog,” then dragging and dropping devices into position on the
PROFIBUS DP bus, represented by the purple line. You must add a master first. Start with the PFM
module.
Devices in the left pane are listed in an indented outline format. Clicking a “+” sign expands a list,
revealing subordinate objects. A “-“ sign indicates that there are no subordinate elements in the list.
Clicking a “-“ sign contracts a list, providing a better overview of the list content, but less detail.
The following window shows the DP Master list expanded to reveal the PFM, a bus master, which has
been dragged and dropped onto the PROFIBUS DP network.
September 2005
3-3
Configuration
SD39PFM-1
Note that the COM PROFIBUS has assigned the first available PROFIBUS address, 1, to the device. As
additional devices are placed on the bus, the program increments the PROFIBUS address from the lowest
available number. An address assigned automatically may be inappropriate and may require modification.
NOTE
At least one DP slave connected to a PFM must be at an address lower
than or equal to 32.
Note, too, that the CP 5611 interface card (or laptop with CP 5511 PCMCIA card), a master assigned the
address 0, should not be added to the graphical display of the DP network. This may be non-intuitive.
The position of a device on this graphical representation of the bus is important only to the degree that it
enables you to visualize and understand your system. It doesn’t matter, for example, whether a device is
dropped above or below the purple line representing the bus. The PROFIBUS address of the devices is, of
course, critical and must be unique and match the setting of the devices itself. Consult the documentation
supplied with each device to determine how to set its address.
If PROFIBUS PA devices are used in the system, the DP bus may include a DP/PA link and coupler,
providing an interface between the DP bus and the PA bus. A DP bus may include other DP devices as
well. The following illustration shows a DP bus consisting of the following:

If a device does not appear on the lists in the left pane of the COM PROFIBUS window, the device’s

file and copy it to the directory C:\SIEMENS\CPBV50\GSD. Then from COM PROFIBUS, select
File > Read in GSD Files, to make the GSD file and the device it represents available to the program.

The essential parameter is the PROFIBUS address, which must match the address assigned to the device.
For DP devices some mechanical means, such as rotary switches or dual in-line package (DIP) switches,
sets the PROFIBUS address. The Siemens CP5611 or 5511 interface card ordinarily takes address 0 and
the PFM module takes address 1. The usual recommendation is that PROFIBUS devices be assigned the
lowest possible addresses to ensure efficient scanning after the network is configured and running.
If you change a switch setting on a slave device, it may not recognize its new address until it has been
powered off and then on again. For slave devices, it necessary to ensure that the “Parm.assign master”
(parameter assigning master) is the PFM. In the illustration below, the PFM is identified by its
PROFIBUS address and name: “#1, Siemens PFM Master.”

3.3 Configuration of DP/PA Link/Coupler Devices
A gateway device interfaces PROFIBUS PA devices with the PROFIBUS DP interface of the PFM.
Siemens offers two such devices with different performance, complexity, and cost.
3.3.1
DP/PA Coupler
A DP/PA coupler provides a physical interface between DP and PA devices. A coupler has no
PROFIBUS address and is transparent to the bus. The DP/PA coupler typically supplies power to the PA
devices that are attached to it. The number of PA devices connected to a coupler is typically limited by
the power-supply current they draw.
Networks that connect PA devices to the DP bus solely through a coupler are common and cost effective
for networks consisting solely of PA devices. Where PA devices are connected to the DP network solely
though a DP/PA coupler, the PA devices must be added to the network with COM PROFIBUS and given
unique PROFIBUS addresses. The PA devices are thus seen as slaves on the DP bus and scanned like
other DP devices.
The baud rate of the DP bus when using a coupler must be set to 45.45 kbaud. In networks consisting of a
PFM and PA devices 45.45 kbaud should be adequate.
This is an important concern, so much so that the COM PROFIBUS program intercepts an attempt to
install a devices that cannot handle the current DP baud rate:
September 2005
3-7
Configuration
SD39PFM-1
As shown in the illustration below, the SITRANS P and SITRANS T3K are both PA devices. The DP/PA
coupler is not shown because it is invisible to the DP network. Without it, however, the PA devices would
be physically incompatible with the DP cabling. The illustration below, as provided by COM PROFIBUS,
thus provides a logical, rather than physical, picture of the DP bus.
3.3.2
DP/PA Link/Coupler
A DP/PA link is an interface between a DP network PA devices, but unlike a coupler it is not transparent.
A link has a unique PROFIBUS address and is acknowledged as a DP device on the DP bus. When a
DP/PA link is mated with a coupler, the combination becomes a link/coupler pair. A single link can
support multiple couplers (a maximum of 5). When shown graphically by the Lifelist.exe program a
link/coupler is represented by a circle, half purple, representing the conventional color of DP cables, and
half blue, the color of PA cables, emblematic of its position in both DP and PA environment (at address
15 in the illustrations):
3-8
September 2005
SD39PFM-1
Configuration
The link/coupler is a master on the PROFIBUS on the PA bus and becomes both a physical and software
interface between the DP bus and a PA bus. PA devices connected to a coupler are assigned PROFIBUS
addresses that are unique to the PA side of their link. Communications between the DP master and the PA
devices are handled through the link/coupler. A DP master sees only the PROFIBUS address of the link,
the coupler has no address, and the addresses of individual PA devices are hidden from the DP master.
The chief advantage to using DP/PA link/couplers is that the link can communicate with PA devices at
the PA baud rate, but permit the DP bus to operate at any DP speed, up to 12 Mbaud.
In COM PROFIBUS a DP/PA link/coupler requires additional configuration to accommodate PA devices
connected to it.
1. Right-click the link coupler to generate the device-specific menu shown in Figure 3–2
2. Select Configure… Then select Module.
The following window appears:
Observe the following when adding modules:
September 2005
3-9
Configuration
SD39PFM-1
•
There can be no gaps in the “Identifier” list. A position can be either be “PA address not used” or
one of the listed modules. Modules are listed if their they are included in the GSD file for the link
(Siem8052.gse). To add an unlisted PA device type to the DP/PA link configuration, the link
GSD file must be updated. As the term is used in the “Module selection for position X “list, a
module represents either a PA device or a PA device module.
•
It is considered a good practice to keep positions allocated to “PA address not used” to a
minimum to ensure efficient scanning and data processing.
•
The PROFIBUS PA address of the PA devices determines their position in the module list. Since
some PA devices are set (or changed) through software, their position should reflect the address
they will ultimately have (equal to the position number + 3). This means that the first available
PROFIBUS PA address for devices connected through a link/coupler is 3. A device in position 1
of the identifier list will be assigned the PROFIBUS address 4, the device in position 2 will be
assigned the PROFIBUS address 5, and so forth.
NOTE
The PFM requires at least one PA slave connected to a DP/PA link to be
at an address lower than or equal to 32.
•
In a system with more than one DP/PA link/coupler, it is possible to have more than one PA
device with the same PA address because the master communicates with the DP/PA link/coupler
using the link/coupler’s unique DP address. The PA devices connected to a link/coupler are
invisible to the master. Their addresses must be unique to their PA bus, but not to the entire
network.
3. Add modules to the list, making a note of their PROFIBUS addresses, which will be required by the
Siemens PDM program. After you have added the first module (or “PA address not used”), the focus
of moves to the next position, and so forth.
4. The following window shows a configuration ready for confirmation through the OK button.
Identifier position 0 and 1 have been assigned “PA address not used” because the PROFIBUS
address of the first PA device (in position 2) has a PROFIBUS address is 5 (PROFIBUS address =
position + 3). The second device in the list has a PROFIBUS address of 6. After adding the last
module, click the OK button.

Configuring and commissioning a network is seldom a linear process. Project requirements change, and it
is common to take tentative steps, to reconsider, and to begin again.
COM PROFIBUS includes a feature that imports an Active DP Configuration into a blank, unnamed
configuration. You can import a known-good configuration, then store the configuration as a file for
subsequent recall, or you can modify a known-good configuration based upon new information or
constraints.
1. Start COM PROFIBUS.

With an online configuration, it is possible in 4-mation to double-click the PFM in the module tree
and display the I/O Channel Table window. Clicking the Display Real Time Values checkbox
produces a update of the current value of input channels as they are scanned:
Comprehensive testing of this kind requires the services of staff who are able to force field I/O to
inject values into the channels scanned by 4-mation. Similarly, by enabling variable control on output
channels, it may be possible to compare expected results with observed results.
Keep in mind that the PDM program can also force devices to output simulated values. See

Installing the COM PROFIBUS and Simatic PDM Licenses
The Simatic PDM license is distributed on one ore more Siemens diskettes, depending upon available
options. This disk labeled “AuthorsW” contains the SIEMENS Authorization Tool software.
Authorization to use the PDM program, like a token, can be transferred, but not duplicated. Authorization
can exist either on the distribution diskettes or on a hard disk drive, but not both simultaneously. It is not
possible to copy the authorization by copying diskettes or the hard disk drive.
To manage authorization, the program AuthorsW.exe does the following:

3.11.3 PFM I/O Channel Common Softlist Parameters
Softlist parameters enable 4-mation to translate between raw binary field I/O and three supported
4-mation channel types: BOOLEAN, packed discrete, and analog. Softlist parameters vary according to
the channel type.
DP_Slave_Addr—default is 126, which must be changed to the PROFIBUS address assigned to the
device. All the APACS+ channels mapped to a multichannel PROFIBUS device have the same
DP_Slave_Addr.
Byte_Offset—The Byte_Offset is the distance in bytes between the beginning of an input or output data
block in the PFM and the first byte of the channel of interest.
The procedures for determining the Byte_Offset for input channels and for output channels are
based upon similar underlying principles. For each of its DP slaves, the PFM allocates an input
block and output block in its memory.
A DP device presents its inputs to the PFM in an unstructured I/O string not longer than 244
bytes. The PFM extracts input data from the string and stores it in its input block it has allocated
for the device. The block is uniquely identified by the DP slave address of the device that
provides the data. The location and length of individual channel data in the block is determined
by three softlist parameters: DP slave address of the DP device, the PROFIBUS data type, and the
Byte_Offset. For input channels, the Byte_Offset points to the first byte of the channel’s data in
the PFM input block for the device. For output channels, the Byte_Offset points to the first byte
of a channel’s output data in the output block.
NOTE
The PFM supports input data lengths of 122 bytes (maximum) and
output data lengths of 244 bytes (maximum) for data transfer into field
devices.
Determining the byte offset so that you can set a channel’s softlist parameters requires an
understanding of the device supplying or receiving data.
In the following illustration, an ET200M, a DP slave that connects with a variety of multichannel
I/O modules, has a PROFIBUS DP address of 9. The ET200M is connected to three modules, a 4
channel analog input module (4AI), a 4-channel analog output module (4AO), and another 4
channel input module (4AI). The data type for the analog channels is signed 16-bit integer (each
channel is 2 bytes long). Given the DP address of the module and the PROFIBUS data type, the
Byte_Offset parameter identifies the beginning of individual channel data in the PFM block. As
this illustration shows, the PFM block for input channels is separate and distinct from the PFM
block for output channels. Note, too, that although the input modules are not contiguous, there are
no gaps in the input data block.

Figure 3–7 Byte_Offset for Typical Input and Output Block
A DP/PA link is another common DP device that sends and receives an I/O string. In the case of
the DP/PA link, downstream PA devices supply or receive the I/O data.
In the case of PA devices connected to the PFM through a DP/PA link, the PA input device with
the lowest PROFIBUS address has its data stored in the input block of the PFM at Byte_Offset 0.
The next PA input device on the bus, in order of ascending PROFIBUS address, has a
Byte_Offset equal to the bytes used by the first device. The third input device has a Byte_Offset
equal to the bytes used by the first two devices, and so forth. Byte_Offset for output devices is
calculated in the same way.
In the illustration below, the DP/PA link device has a PROFIBUS address of 11. The addresses
of the PA devices (5, 7, and 8) must be unique to their PA bus, and there may be gaps. In the
illustration, the data type of each PA device is a PA floating point structure, which consists of 4
bytes of data and 1 byte of status per channel. The Byte_Offset for the channel associated with
the PA address 5 is 0, the Byte_Offset of device with address 7 is 5, and the Byte_Offset of the
device with address 8 is 10. See Figure 3–8

Input and output data blocks in the PFM are distinct and independent of one another. The
Byte_Offset for an input channel is thus independent of the Byte_Offset for an output channel.
The COM PROFIBUS program provides a useful tool for determining or confirming
Byte_Offset:
1. With the PROFIBUS network configured through COM PROFIBUS and Simatic PDM, open
COM PROFIBUS and either open the current configuration or import it from the DP master
2. Select the DP/PA link.
3. From the menu bar select Services > Observe/Control/Inputs/Outputs.
The resulting display shows the current value in bytes of PA devices connected to the DP/PA
link. You can count the bytes of input or output preceding a device of interest to determine the
device’s Byte_Offset. Keep in mind that the data stream from a PA device includes one byte of
status per channel. The illustration below shows data input from two PA floating point devices,
both providing four bytes in data and one byte of status (for example, 80 hex).
In the example, the PROFIBUS PA address of the first device is 5, so the device is located in
position 2 (if its PROFIBUS address were 3, the lowest permissible address for a PA device
connected to a DP/PA link, the device would be located in position 0 ). The Byte_Offset of the
input channel of the first device, regardless of its address, is always 0.
The Byte_Offset of the input channel of the next device (in position 3) is 5, which is the number
of input bytes preceding it. If there were a device in position 4, the Byte_Offset for its input
channel would be 10, again determined simply by counting the preceding input bytes. See Figure
3–9.

Profibus_Slot_Number—in devices with more than one slot (module), the slot number identifies the slot
if a PROFIBUS diagnostic message is reported. The Profibus_Slot_Number parameter has no
effect on data I/O; it is used only for APACS error reporting.
Profibus_Ch_Number—in devices or modules with more than one channel, the channel number
identifies the channel if a PROFIBUS diagnostic message is reported. The Profibus_Ch_Number
parameter has no effect on data I/O; it is used only for APACS error reporting.

Min_Scale/ Max_Scale: The module linearly scales raw data to engineering units for each channel. The
scaling algorithm (equation below) uses the Min_Scale/Max_Scale parameters set by the user.
For example, given a 4 to 20 mA input, a MinScale of 0.0 and a MaxScale of 100.0; if the input
to the channel is 12 mA, the scaled value is 50.0.
Min_Scale and Max_Scale can be any real (REAL) number (Real numbers are valid between 3.4028E38 and +3.4028E38.)
RawLoCounts: specified by the user to define the value of the associated process variable. The default is

RawHiCounts: specified by the user to define the value of the associated process variable. The default is
27648 (0x6c00) when the channel value equals max scale.

4 Maintenance
This section describes how to maintain the PROFIBUS Fieldbus Module (PFM) and its associated
transition board. These items require minimal maintenance. Some routine maintenance is recommended
in the form of a visual inspection and possible cleaning. A module’s operating status is shown by Light
Emitting Diodes (LEDs) located on its bezel. Replacement procedures are provided for the module and its
termination board.
DANGER
Explosion hazard
Will cause death, serious injury or property damage
•
•
•
In potentially hazardous atmosphere, remove power from equipment before
connecting or disconnecting power, signal, or other circuit, or extracting/inserting
module.
Observe all pertinent regulations regarding installation in hazardous area.
Ensure all devices are rated for hazardous (classified) locations.
4.1 Tool Requirements
The following tools are necessary for servicing:
• Common electronic servicing hand tools
• Digital multimeter
4.2 Visual Inspection
The PFM and its associated assemblies should be subjected to periodic visual inspection. The frequency
of inspection is dependent on the severity of the operating environment.
The primary aim of the inspection is to reveal any excessive accumulation of dust, dirt, or other foreign
material adhering to the surfaces of the termination hardware and protective covers of the module.
Accumulation of dirt and dust prevents efficient heat dissipation and can contribute to module or system
failure. Refer to section 3.3 for cleaning instructions. Note that a PFM module installed in a cabinet
complying with the NEMA (National Electrical Manufactures Association) 12/IP55 specification need
not be inspected for cleanliness.
4.3 Cleaning
Cleaning the PFM involves brushing or vacuuming the protective covers to restore cooling efficiency that
degrades by the accumulated dust, dirt, or other foreign materials.
September 2005
4-1
Maintenance
SD39PFM-1
Cleaning a transition board consists of careful brushing and vacuuming to remove accumulated dust and
dirt harboring chemical particulate that can accelerate terminal or connector contact corrosion. When
cleaning the termination hardware area, be careful not to disturb the field wiring.
WARNING
Electrical shock hazard. Remove power from all involved wires and
terminals.
4.4 Troubleshooting
A module’s operating status and errors are indicated by its status LEDs. Also, error codes and related
diagnostic messages are displayed by the 4-mation configuration software and the Diagnostic Logger
utility. Details of error codes and messages are available in the following documents:

Table 4–3 BF (Bus Fault) LED
Indication
Meaning
Off
No error, PFM is in communication with all configured
slaves.
On (solid red)
Bus error, Possible cause: short circuit on the bus,
differing baud rates, HSA less than master address, faulty
RS 485 circuit.
Flashing RED (1/sec, 50% duty
cycle)
Data communication is not being performed with at least
one of the configured slaves.
Any slave of the PFM can affect the BF LED. Only
slaves that are relevant to PFM I/O channels generate
4-mation errors.
Another way to troubleshoot the PFM is develop a test configuration using the 4-mation configuration
software. This test configuration is to be used in an off-line service environment. A test configuration can
be used to exercise each channel’s operation.
To obtain spare or replacement parts, refer to Section 4.7. To return a failed assembly to the factory for
repair, refer to subsection 2.1.4. There are no user-serviceable parts within a PFM module.
4.5 PFM Removal/Replacement
During operation, the PFM module communicates with its associated control module (ACM+) over the
IOBUS. This bus runs continuously along the backplane of a module rack. A PFM can be removed from
or installed into a rack without removing power from the module slot, from field circuits, or from the
module rack.
4.5.1
Removal
1. As detailed in Figure 2–3, pull open the bezel’s pivoted top and bottom handles to expose the
module’s slotted captive mounting screws. Loosen the screws.
2. Grasp the top and bottom handles and pull the module from the rack.
3. Place the module in a static shielding bag and package it for safe return. Refer to section 3.9 for return
instructions.

PROFIBUS.
4.6 Transition Board Removal/Replacement
4.6.1
Removal
Refer to the mechanical details of Figure 2–3.
1. As necessary, take appropriate steps to shutdown the processes monitored or controlled by the field
devices connected transition board.
2. Remove the associated PFM from its slot in the rack. Place the module in a static shielded bag for
protection.
3. Disconnect PROFIBUS DP cable from the DB-9 connector.
4. As shown in Figure 2–2, use a screwdriver to loosen the transition board from its local termination
panel.
4.6.2
Replacement
Follow the procedure in subsection 2.2.1
4.7 Spare and Replacement Parts
One spare PFM should be stocked for every 10 in service. Spare and replacement assemblies can be
ordered from one of the addresses in the Warranty statement and the end of this manual or through a local
Siemens representative. Assembly part numbers are listed in Section 5 and printed on most modules.
When ordering, provide the model number from the module’s nameplate to be replaced or spared. A
purchase order number should also be included.
There are no user-serviceable parts within PFM module. See Section 6 for descriptions of spare and
replacement parts
4.8 Maintenance Records
An accurate record keeping system for tracking maintenance operations should be established and kept up
to date. Data extracted from the record can serve as a base for ordering maintenance supplies, including
spare parts. The record can also be useful as a troubleshooting tool. In addition, maintenance records may

6.2 Software
COM PROFIBUS V5.1 (Part Number PS02-2324V3.02) is used to configure master and slave
addresses and bus parameters for PROFIBUS DP networks. This software is delivered with the PFM and
does not have to be ordered separately as a line item.
PDM V5.1 + SP2 This software is needed to parameterize PROFIBUS DP/PA and/or any HART
devices that are connected to the PFM via a linking device or remote I/O module. A control system that
does not have any DP/PA or HART devices (connected to the PFM via ET-200M) does not need this
software. Customers will have to purchase appropriate licenses (floppies) in order to be able to use
PDM. A customer will need to order item 1 and one or more of the options listed in Table 6–7 below.
