BMx CRA 312 10 In the System

BMx CRA 312 10 Role

The BM• CRA 312 10 module is a communication module in a Modicon X80 Ethernet remote I/O drop.

BM• CRA 312 10 module features:

• In a Modicon M580 solution, these modules exchange data with the BME P58 •••• CPU.

• In a Quantum Ethernet I/O solution, these modules exchange data with the Quantum PLC head module: 140 CRP 312 00.

• In addition to its communication function, a BM• CRA 312 10 module can time stamp any discrete I/O on discrete modules located in the drop.

BM• CRA 312 10 module evaluates periodically discrete input and output values and if a change is detected it is time stamped and stored in the module internal local event buffer. This buffer makes the information available for the final client and its behavior needs to be defined in Control Expert software.

For time stamping application, the BM• CRA 312 10 module requires a direct link to an accurate NTP server time source and the time stamp resolution depends on the architecture.

Discrete Inputs and Outputs

The BM• CRA 312 10 module is able to time stamp any discrete module located in the drop.
