The GR200-ECS module is equipped with EC series PLC and MC series PAC products for remote rack expansion. The module communicates with the master via EtherCAT and can be adapted for use with the GL200 series expansion IOs, which have their own local IOs and support 16 channels of inputs and 16 channels of outputs (Sink/Source). Standard ESI files are available for third-party devices with EtherCAT masters.
The GR200-PNS module is used with EC series PLC and MC series PAC products to extend the GL200 series IO modules via the Profinet bus. The module itself has 16 digital input channels and 16 digital sink output channels. GSD files are provided to match devices with third-party Profinet masters.
