Communication Modules and Communication Interface Modules

The Communication Module CM579-PNIO: CM579-PNIOPROFINET network. It is connected to the Processor Module via an internal communication bus.

The Communication Interface Modules CI50x-PNIO act as IO Devices for PROFINET network. The difference of those devices can be found in their input and output characteristics Comparison: Comparison of the CIxyz-PNIO Modules
