The OMRON device communications enabler selects the protocol for a device based on the model type and address you configure for the device.
If you select the CV-Series, CV-Series Static, CV-Series Ext., CV-Series Ext. Static, CVM1-V2 or CVM1-V2 Static model type, the OMRON communications enabler uses CV-mode (FINS) protocol.
If you select the C-Series or C-Series Static model type, the protocol depends on the device's address.
If the address indicates the device is on a local Host Link network, the OMRON device communications enabler uses C-mode protocol.
If the address indicates the device is on a subnetwork, then the OMRON device communications enabler uses CV-mode protocol.
