Modbus Communications
Connectivity to OpenComms-485 using Modbus
This design specification describes the Modbus communications protocol as
supported by the OC-485 interface card. It includes information on how to pass
information to and from the OC-485 card via Modbus. It is also intended to help
facilitate answering questions regarding supported types, frame format, function
code support etc.
Implementation Basics
Protocol controls the language structure or message format between devices in
other words, the rules for communication. The rules for communication include
how master and slave devices initiate communications, as well as unit
identification, message handling and error checking. Modbus protocol simply
refers to the control of the query and response cycles between master and slave
devices.
The OC-485 card is configured to act as a slave device on a common network.
This common network can be a multi-drop configuration over EIA-485, where
multiple slaves reside on a common wire or loop.
Transmission Format
The OC-485 interface card supports Modbus RTU (Remote Terminal Unit)
transmission modes. . See chart below.

Modbus Packet Format
Each Modbus packet consists of the following fields:
• Device Address
• Function Code
• Data Field(s)
• Error Check Field
Device Address:
The address field immediately follows the beginning of the frame and consists of
8-bits (RTU). This bit indicates the user assigned address of the slave device
that is to receive the message sent by the attached master device.
Each slave must be assigned a unique address and only the addressed slave will
respond to a query that contains its address.
Function Code:
The function code field tells the addressed slaves what function to perform.
Function codes are specifically designed invoke a specific action by the slave
device. The function code range is from 1 to 127.
OC-485 Modbus server supports the following Modbus function codes.
Code Function Description
01 Read Coils Read from 1 to 2000 contiguous status of coils managed
by the server. Coils in the response message are packed
as one per bit of a byte, 1=ON and 0=OFF. If the
requested quantity of coils is not a multiple of 8, zeros
are padded in the final byte.
02 Read Discrete

03 Read Holding

Coils
Read from 1 to 2000 contiguous status of input status
managed by the server. Discrete inputs in the response
message are packed as one per bit of a byte, 1=ON and
0=OFF. If the requested quantity of inputs is not a
multiple of 8, zeros are padded in the final byte.
Read the contents of contiguous block of 1 to 127
holding registers. Data are packed as two bytes per
register; the first byte contains the high order bits.
Read the contents of contiguous block of 1 to 127 input
registers. Data are packed as two bytes per register; the

in coil section.
Write a value into a single holding register;
Force each coil in a sequence of coils to either ON or
OFF.

16 Write multiple
Registers
Write values into a block of contiguous registers (1 to
120)
Data Field(s):
The data field varies in length depending on whether the message is a request or
a response to a packet. This field typically contains information required by the
slave device to perform the command specified or to pass back data to the
master device.
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.
RTU Framing
The example below shows a typical Q/R from a OC-485 interface card. In common
terms, the master device initiates a query asking slave device 2 for holding registers
starting at holding register 40051 (decimal 50) and including next 2 Registers (3 total).
