understanding of the Modbus Protocol. Only limited
information is presented here regarding the Modbus Protocol
specifications.
6 Version 2
1.3. Organization of this Manual
This document provides all application-specific information necessary for developing a Modbus
Master application program for interfacing with the Protocol 3™ slave controller.
1.3.1. Reference Documents
The following Modbus Protocol documents should also be helpful and relevant:
For a complete description of the Modbus protocol refer to the description provided at
http://www.modicon.com/ or http://www.modbus.org/.
1.4. Serial Communications
1.4.1. Supported Protocols
The unit supports two communication interfaces Modbus RTU and Modbus TCP. Modbus RTU
is supported through the RS485 interface and Modbus TCP is supported through the optional
Ethernet Module.
For a complete description of the Modbus protocol refer to the description provided at
http://www.modbus.org/.
1.4.2. RS485 Configuration
The RS485 address, bit rate and character format are configured via the front panel from the
Comms Configuration menu.
Physical layer configuration settings possible are:
Data rate: 4800, 9600, 19200, 38400, 57600 or 115200 bps
Parity: None (default), Even, Odd

Modbus Programming Manual ABOUT THIS MANUAL
Version 2 7
Character format: Always 8 bits per character.
Device Address: See below.
1.4.3. RS485 Device Addressing
The instrument must be assigned a unique device address in the range 1 to 255. This address is
used to recognize Modbus Queries intended for this instrument. With the exception of globally
addressed broadcast messages, the instrument ignores Modbus Queries that do not match the
address that has been assigned to it.
The instrument will accept broadcast messages (global queries) using device address 0 no matter
what device address is assigned. No response messages are returned for globally addressed
Queries.
1.4.4. Ethernet Configuration
For Modbus TCP communications (Modbus over Ethernet), the IP address can either be assigned
by a Dynamic Host Configuration Protocol (DHCP), BootP or AutoIP server on the network, or
manually assigned using the IP address allocation software tool.
The supported data rates 10/100BASE-T (10 or 100 Mbps) are automatically detected.

ABOUT THIS MANUAL Modbus Programming Manual
MODBUS
SLAVE
QUERY
RESPONSE
Figure 1. Modbus Link Layer.
8 Version 2
1.4.5. Link Layer
A Query (or command) is transmitted from the Modbus Master to the Modbus Slave. The slave
instrument assembles the reply to the master (see Figure 1).
MASTER
INSTRUMENT
A message for either a QUERY or RESPONSE is made up of an inter-message gap followed by a
sequence of data characters. The inter-message gap is at least 3.5 data character times - the
transmitter must not start transmission until 3 character times have elapsed since reception of the
last character in a message, and must release the transmission line within 3 character times of the
last character in a message.
Note:
Three character times is approximately 0.25ms at 115200 bps, 0.51ms at 57600 bps, 0.75ms at
38400 bps, 1.5ms at 19200 bps, 3ms at 9600 bps and 6ms at 4800bps.
Data is encoded for each character as binary data, transmitted LSB first.
For a QUERY the address field contains the address of the slave destination. The slave address is
given together with the Function and Data fields by the Application layer. The CRC is generated
from the given address, function and data characters.
For a RESPONSE the address field contains the address of the responding slave. The Function
and Data fields are generated by the slave application. The CRC is generated from the address,
function and data characters.
The standard MODBUS RTU CRC-16 calculation employing the polynomial 216+215+22+1 is
used.

1.4.7. Function Descriptions
The following is interpreted from the Modbus Protocol Description obtainable from
http://www.modbus.org/. Refer to that document if clarification is required.
In the function descriptions below, the preceding device address value is assumed, as is the
correctly formed two-byte CRC value at the end of the QUERY and RESPONSE frames.
Function 03 / 04 - Read Holding/Input Registers
Reads current binary value of data at the specified word addresses.
In the response the “Number of Bytes” indicates the number of data bytes read from the
instrument. E.g. if 5 words are read, the count will be 10 (A hex). The maximum number of
words that can be read is 64. If a parameter does not exist at one of the addresses read, then a
value of 0000h is returned for that word.

The Modbus parameter register addresses are detailed in the following sections.
The Access column indicates if a parameter is read only (RO) or if it can also be written to
(R/W).
Note:
Some parameters that do not apply for a particular configuration will accept reads and
writes. Read only parameters will return an exception if an attempt is made to write values
to them.
1.4.8. Data Formats
Data can be read or written in three formats: Integer Only, Integer with 1 Decimal Place and
Floating Point Number.
The Modbus Address column shows the register address for each parameter in integer format.
Other formats can be calculated from the Integer Only address.
When working in Hexadecimal, the format calculations are:
Address for Integer with 1 Decimal Place = Integer address plus 0x4000
Address for Floating Point = Integer address multiplied by 2, plus 0x8000
When working in Decimal, the format calculations are:
Address for Integer with 1 Decimal Place = Integer address plus 16384
Address for Floating Point = Integer address multiplied by 2, plus 32768
