Comparison of the CIxyz-PNIO ModulesΒΆ
The PROFINET IO 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 CM579-PNIO acts as IO Controller 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 act as IO Devices in a PROFINET network.
Additionally the communication module CM589-PNIO(-4) can be used to setup a AC500 PLC to act as IO Device in a PROFINET network.
The difference of the CIxyz-PNIO devices can be found in their input and output characteristics Comparison of the CIxyz-PNIO Modules. The characteristics for CM589-PNIO(-4) can be found in the device description for CM589-PNIO <no title>.
