3150-MCM PRS

The Modbus Master/Slave Communication Module is designed to allow SLC processors to interface easily with Modbus protocolcompatible devices and hosts. The inRAx module acts as an input/output module between the Modbus network and the Rockwell Automation backplane. The data transfer from the SLC processor is asynchronous from the actions on the Modbus network. A 4000-word register space in the module exchanges data between the processor and the Modbus network. Many host SCADA packages support the Modbus protocol, while devices commonly supporting the protocol include several PLCs, as well as many other third party devices in the marketplace.
