6.0 MODBUS
6.1 Introduction
This design specification describes the Modbus communications protocol as supported by the
monitoring/metering system. For packet details and examples, refer to Appendix I of this
document. The TCP or RS485 communication port must be active and configured properly.
6.2 Supported Protocol Parameters
Implementation Basics
 operates as slave device only
 The maximum number of bytes contained within one packet of communications is
255. This equates to supporting a read request for 125 registers.
Transmission Format
Only Modbus ASCII mode is not supported.
The RS485 controller only supports the following format:





8 data bits
no parity
1 stop bit
Refer to register map for baud rate supported
Device address 1 - 247
Packet Framing and Timing
Three timing intervals as follows:
 Maximum time between two consecutive bytes within a packet < 3.5 character
times
 Minimum time between two consecutive packets is > 3.5 character times
 Maximum response time from a Master request to a slave response is < 50
milliseconds
6.3 Supported Function Codes
Function # 03 (03h) — Read Holding Registers
This function code allows the master to read one or more consecutive data registers
(up to 125). Refer to Register Map section for details
Function #16(10h) — Preset Multiple Registers
This function code allows the master device to modify the contents of consecutive
configuration registers within the system. This monitoring/metering system
currently only supports the following Preset Multiple Register addresses (decimal):
40026-40029, 40044-40051 and 40079.
The maximum allowable write data registers are 10.
If a function code #16 command is issued to registers outside of these
corresponding register ranges, the unit will respond with an invalid address range
Exception.
Exception Responses
If the Modbus master device sends an unsupported command, attempts to read an
invalid holding register, or attempts to write invalid data, the unit will issue an
exception response. Error codes of 01, 02, 03 and 04 are currently supported. Refer
Appendix I for details.

6.5.1
MODBUS RTU Overview
This section describes some of the details of the Modbus communications protocol as
supported by the Monitoring/Metering system. It includes instructions on how to
communicate with devices via the Modbus network. This documentation should be used by
individuals wishing to integrate this system into their facility by developing software to
communicate with it. Additional detail of Modbus specification can be found on the Modbus
organization’s Web site http://www.modbus.org/specs.php.
6.5.2
MODBUS Protocol
Modbus RTU Packet Format
Every Modbus Packet consists of the following fields:




Device Address Field
Function Code Field
Data Field
Error Check Field
Device Address Field. This is the first byte of each Modbus RTU transmission. This device
address is a number limited to the range of 1 - 247 and is associated with a single device
configured with a matching address. Only the slave device whose address matches the
value in this field will respond to the specified command.
Function Code Field. This is a second byte of each transmission and represents the
commanded action to the slave device (for queries from the master) or the action that
was taken by the slave device (for responses from the slave). Codes between 1 and 127
are defined as Modbus RTU functions. The function codes are detailed on section 6.3
“Supported Function Codes”.
Data Field. The data field varies in length depending on whether the message is a request
or a response packet. This field typically contains information required by the slave
device to perform the command specified in a request packet or data being passed back
by the slave device in a response packet.
Error Check Field. The error check field consists of a 16 bit (2 byte) Cyclical Redundancy
Check (CRC16). It allows the receiving device to detect a packet that has been corrupted
with transmission errors.
6.5.3
Packet Framing and Timing
Because the Modbus RTU protocol does not define any explicit packet synchronization bytes,
synchronization is accomplished implicitly with the use of silent intervals. According to the
Modbus RTU standard, all messages must start with a silent interval of at least 3.5 character
times. This means that every byte within a packet must follow the previous byte by fewer than
3.5 character times based on the baud rate. And every new packet of data must wait at least
3.5 character times after the packet that had preceded it.

Function #16(10h) — Preset Multiple Registers
This function code allows the master device to modify the contents of consecutive
configuration registers. The data registers are always 16 bit (two byte) values,
transmitted high order byte first. Refer to Register Map for details about the data
register type definitions. Only those registers with the register type RW defined are
allowed to process with function code #16. If a function code #16 command is
issued out of these corresponding register ranges, the system will respond with an
invalid address range Exception Response (see section of Exception Responses).
The maximum number of registers that can be preset with a single 10H command is
10.

Exception Responses
If the Modbus master device sends an unsupported command, attempts to read an invalid
holding register, or attempts to write invalid data, the system (Modbus slave) issues an
exception response.
The format for the exception response is as follows:
1. SLAVE ADDRESS
2. FUNCTION CODE (with the most-significant-bit set to a 1)
3. ERROR CODE
4. CRC16 — low order byte
5. CRC16 — high order byte
*Note: The high order bit of the function code has been set to one to indicate an exception
response has been generated.
Exception codes supported:
01 Illegal function - The slave does not support the function code contained in the master
query packet.
02 Illegal data address - The slave does not support the Holding Register address referenced
in the data field of the master query packet.
03 Illegal data value - The slave does not support the data referenced in the data field of the
master query packet.
04 Device failure - The addresses slave is unable to perform the action requested due to an
internal failure or malfunction.

7.5 Category A, B, & C Surge Events
When the SPD detects a surge/transient, the SPD monitoring system automatically records a
new event and details the phase, the event duration, and the severity (the amount of letthrough voltage after the SPD has performed its function).
The surge/transient event is categorized by the monitoring system as a Category A, B, or C
surge event. Industry standard ANSI/IEEE C62.41 categories, the SPD source voltage, event
let-through voltage, & SPD performance ratings are referenced when categorizing surge
events.
Category
Surge Level
A
Surge events less than [6kV, 3kA]
B
Surge event between [6kV, 3kA] and [20kV, 10kA]
C
Surge event greater than [20kV, 10kA]

9.0 Surge Protective Devices
It takes a variety of surge protective products to protect your mission-critical equipment. ASCO’s
comprehensive product portfolio ensures you’ll be able to provide peace-of-mind surge protection at
all “SURGEHOTspots” within the system. In addition to the traditional AC panel surge protection, all
critical communication wires within a system should also be connected through a UL approved surge
protective device.
