Receiving Explicit Messages

CJ-series DeviceNet Unit contains a PLC Object. The Unit will receive messages addressed to the PLC
Object, process service requests addressed to the CPU Unit, and return responses.

The following services are provided by the PLC Object.

•

CPU Unit status read/write

•

CPU Unit I/O memory read/write

The explicit messages can be received from the following sources:

•

DeviceNet masters made by other manufacturers

•

PLCs with C200H-series DeviceNet Master Units (C200HW-DRM21-V1)

•

PLCs with CVM1/CV-series DeviceNet Master Units (CVM1-DRM21-V1)

•
