About OMRON Host Link Communications

The OMRON Host Link communications enabler supports OMRON C-Series and CV-Series programmable controllers in point-to-point and multi-drop configurations with one device where the CIMPLICITY Host Link Communications enabler acts as the client.

The OMRON Host Link Communications provides read and write access to the OMRON programmable controllers via a Host Link System Network. You can make RS-232 or RS-422 connections through the built in Host Link interface on the programmable controller's CPU or through an optional Host Link Unit in the OMRON PC's rack.

All communication commands are implemented as active/standby communications where the CIMPLICITY OMRON Host Link communications enabler acts as the client responsible for requesting data from or writing data to OMRON programmable controller(s). Unsolicited data sent from OMRON programmable controllers is not supported.

You can connect up to 32 OMRON programmable controllers to a host computer via multi-drop RS-422 line.

You can connect to one OMRON C-Series or CV-Series programmable controller via an RS-232 line.
