Rockwell Automation Remote I/O to
Modbus Master/Slave Gateway
5601/5602-RIO-MCM(4)
The ProLinx Rockwell Automation Remote I/O Adapter to Modbus
Master/Slave Gateway creates a powerful connection between
devices on a Remote I/O network and Modbus devices. This standalone DIN-rail mounted protocol gateway provides one Remote I/O
port and up to four serial ports.
Rockwell Automation Remote I/O to
Modbus Master/Slave Gateway
5601/5602-RIO-MCM(4)
The RIO-MCM modules are the ideal solution for the many
applications where Remote I/O connectivity can be used to integrate
Modbus devices into a system. The Remote I/O gateway is a
powerful module designed with both Client and Server support,
enabling easy connection to Rockwell Automation PLCs (CLX, SLC,
PLC, CPLX, and similar devices). In combination with the Modbus
device support, the module provides a very powerful interface to the
many Modbus devices which are in use in the industrial marketplace
today. Applications for the module are found in most industries,
especially Manufacturing, Oil and Gas, Electrical Power and Food
Processing.

The RIO interface is an adapter (slave) which can be connected to a
scanner (master) that controls the data transfer. The module also
supports limited high speed data transfer via the Input and Output
images.
The Modbus protocol driver supports Master and Slave
implementations of the protocol. All Modbus serial ports are
individually configurable, providing a very powerful and flexible host
or device interface solution.
Rockwell Automation Remote I/O
The RIO interface is an adapter (slave) and is connected to a
scanner (master) that controls the data transfer. For example, the
master/slave relationship can be accomplished using the RIO module
(adapter/slave unit) with a Rockwell Automation PLC5
(scanner/master unit). Ladder logic must be programmed into a PLC
to perform BTR/BTW commands to receive and transmit data
between the module and the PLC. The module also supports limited
high speed data transfer via the input and output images.
