Also asked, what is OPC server in Scada?OPC Server. Download OPC Server. Open Platform Communications (OPC) is a series of standards and specifications for industrial telecommunication. OPC specifies the communication of the real-time plant data between control devices for different developers of SCADA software.Subsequently, question is, what is the difference between OPC and PLC? While ordinary portland cement (OPC) may contain up to 5% limestone, PLC contains between 5% and 15% limestone. Regarding this, how does OPC Server work? The OPC server is a program that translates the hardware communication protocol used by a PLC into the OPC protocol. The OPC client software is a program that connects to the hardware, such as an HMI. The OPC client communicates with the OPC server to receive data or send commands to the hardware.Why is OPC needed?An OPC server reduces the load on data source devices as it enables communication with several applications, while having only one connection with the data source. This reduces multi-access from the data source, and hence reduces the load on the data source.
