Comparison of the CIxyz-PNIO Modules

The PROFINET® devices combine the advantages of decentralized I/O modules with the reaction time of AC500 mounted central I/O modules. The devices for PROFINET® provide the extension -PNIO in the device name.

The Communication Module CMxyz-PNIO is the IO Controllers in a PROFINET® network. It is connected to the Processor Module via an internal communication bus. Depending on the Terminal Base, several Communication Modules can be used for one Processor Module.

The Communication Interface Modules CIxyz-PNIO are the IO devices for PROFINET®.

The difference of the CIxyz-PNIO devices can be found in their input and output characteristics.
