A software interface guaranteeing open communication

The SOFREL OPC server is a standard software interface offering a broad range of communication possibilities.

OPC (OLE for Process Control) is the information exchange protocol between industrial software applications in a Windows environment. It offers open communication thanks to the inter-operability of devices from different manufacturers.

The OPC standard thus frees users from the constraints imposed by proprietary protocols.

LACROIX Sofrel is fully committed to this approach with its OPC Server software , which allows supervisors having an “OPC client” interface to communicate with all SOFREL devices.
