Modbus

An additional protocol layer is available for speaking to I/O devices. Modbus is an RS-485 protocol 
that packages information in binary packets that are sent as part of a TCP/IP packet. 
Modbus/TCP requires an Ethernet connection between master and slave. Modbus/TCP also requires 

that all slaves communicate with their masters over port 502. See the IH command to setup port 
communication for the RIO. 
The Modbus protocol has a set of commands called function codes.  As a Modbus Class 1 device, the 
RIO-47xxx supports the 10 major function codes:

Table 3.2: Supported Modbus function codes and descriptions.

All modbus function codes listed in Table 3.2 are supported by the RIO when it operates as a master 
(client) or when it operates as a slave (server).
Note: The remainder of this chapter uses the '$' symbol to signify that numbers are in hexadecimal 
notation. 

As a Modbus Master

The RIO-47xxx provides three method of Modbus communication as a master:
1. The first method of Modbus communication uses standard Galil commands. The following 

commands support Modbus:

@IN[], @AN[], @OUT[], SB, CB, OB, and AO

See the RIO command reference individually for each command on how to address a Modbus 
slave.

2. The second method uses the MB command that requires the user to enter a select a few key 

parameters and allows the controller to build the Modbus packet. The formats vary depending 
on the function code that is called.  For more information refer to the MB command in Command
Reference

3. The final method allows the user to send raw Modbus packets. This gives the user complete 

control over the creation of their Modbus packet including transaction identifiers, protocol 
identifiers, length field, Modbus function code, and data specific to that function code.. To send a
raw Modbus packet the user must set the MB command with a function code of –1. For more 
information refer to the MB command in Command Reference

The following sections provide a full description of each method.
