Description
P
GK473 gateway (interface converter) enables networking
of approx. 32 spindle position displays (SPA) of the Baumer
IVO multicon system (for example N 140, N 141, N 150 and
a fieldbus-capable control (PLC). The gateway is converting
the SPA’s RS485 interface into a fieldbus interface and viceversa. Four LEDs serve as status indicators. The gateway is
capable of Auto-Check functions what means a relief to the
control.
One bus segment allows operation of several gateways for
connecting more SPAs. The gateway provides a small housing for DIN rail mounting, Node-ID and bus termination can
be parameterized.

Auto-Check functions
Auto Scan SPA
If this function is activated, during operation the gateway
will proceed a continous AutoScan of all SPAs connected
checking whether they are “in position”. This information
can be collected by special command for fieldbus readin
upon request. AutoScan spares the fieldbus master of cyclic
scanning every SPA himself.
Auto Message SPA Error
If this function is activated, in the following events the
gateway will automatically provide a message without prior
request by the fieldbus master. After all SPAs having been
previously in status “no error” (“in position” or “not in position”) now at least one SPA is in “error” status. After previously at least one SPA having been in “error” status, now all
SPAs are again “in position” or “not in position”.

Auto Message SPA Position
If this function is activated, in the following events the
gateway will automatically provide a message without prior
request by the fieldbus master: After all SPAs having previously been “in position” this is no longer valid for at least
one SPA. The message will also be given if previously at
least one SPA was not “in position” and now all SPAs are “in
position” again.

DeviceNet
DeviceNet is based on CAN Bus (Layer 2), in line with CANBus standards ISO / DIS 11898 CAN 2.0B. Optional
transmission rates of 125 kBit/s, 250 kBit/s and 500 kBit/s.
The baudrate is set by DIP switch. The user address (MAC
ID, 0..63) is set by help of two rotary switches. Since there
Is no existing standard DeviceNet profile for this kind of
gateway it is manufacturer-specific. DeviceNet connection is
by integrated 9-pin D-SUB connector (female). Any CAN
bus loops required can be realized in the connector itself
(not included in the delivery).
CANopen
The CANopen interface is in line with CAN-Bus standard
ISO / DIS 11898 CAN 2.0B. Optional data transmission
rates are 10 k, 20 k, 50 k, 100 k, 125 k, 250 k and 500
kBaud. The baudrate is DIP-switch settable, the user
address is set by two turnable switches. The supported
CANopen- communication profile is DS 301. Since there is
no CANopen application profile available for this kind of
gateway it is manufacturer-specific. CANopen connection is
by integrated 9-pin D-SUB-connector (female). Any CAN
bus loops required can be effected in the connector itself
(not included in the delivery).
Profibus
The Profibus-DP interface is in line with Profibus standard
DP-V0 (cyclic communication) according to DIN EN 50170.
Optional data transmission rates are 9600, 19200, 93,75 k,
187,5 k, 500 k, 1.5 M, 3 M, 6 M and 12 MBaud. The baud
rate applied is automatically recognised. Since there is no
standard gateway profile available it is manufacturerspecific. Profibus-DP connection is by integrated 9-pin DSUB connector (female). Any Profibus loops required can
be realized in the connector itself (not included in the
delivery).

RS485
The serial interface is conform to EIA RS485.
Max. 32 multicon spindle positioning displays can be
networked in any combination to RS485 bus.

Function modules
Profibus function module
Function modules are capable of taking over basic functions
in the communication between PLC and Profibus gateway
what means a considerable relief to the S7 operator.
Step7® provides convenient implementation of the Baumer
IVO multicon project. The function modules written into AWL
sub-software (FC’s) are availabe as pure text files and
additionally as complete Step7® example project. This
allows convenient individual modifications. The functions
comprise reading and writing of current and target values
into the spindle position displays (SPA), profile administration and storage in the PLC, automatic address designation
for the SPAs connected as well as bit parameter administration. Other integrated functions enable optimized evaluation
of automatic gateway scanning functions. The function
modules are intended for a Siemens® S7 300DP® and
available in AWL, however it can be taken for granted that
by slight modifications they can be easily implemented into
other AWL-capable PLCs by Siemens.
