RealiteQ developed its own OPC server and Client to connect any third party HMI/SCADA/ERP/BI software for Existing Control Rooms.


OPC (OLE for Process Control), OPC is a software interface standard that allows ​Windows programs to communicate with industrial hardware devices.

OPC is implemented in server/client pairs. The OPC server is a software program that converts the hardware communication protocol used by a PLC into the OPC protocol. The OPC client software is any program that needs to connect to the hardware. The OPC client uses the OPC server to get data from or send commands to the hardware.

The value of OPC is that it is an open standard, which means lower costs for manufacturers and more options for users. Hardware manufacturers need only provide a single OPC server for their devices to communicate with any OPC client. Software vendors simply include OPC client capabilities in their products and they become instantly compatible with thousands of hardware devices.
