OPC (OLE for Process Control) is the protocol for data exchange between industrial software in a Windows environment. It is a standard software interface providing genuine communication openness thanks to the interoperability of the different manufacturers’ hardware. The OPC standard thus frees users from the obstacles imposed by proprietary protocols.

LACROIX Sofrel has committed fully to this approach by offering SOFREL OPC: an OPC Server software package enabling supervisors with an «OPC client» interface to communicate with all SOFREL Remote Terminal Units.
