This program implements a simple OPC DA2 server that polls a file on a local or network drive, reads updated values from that file, and then posts them via the OPC interface.
What problems can be solved with File OPC Server?
This way, you can easily create an OPC server and use it in a system that doesn't support the OPC functionality, if it is inexpedient to add that functionality. You can create and update the input file by using scripts, which allows you to implement support for the OPC interface in a programming language that lacks that capability.
You can keep the input file on a network drive to build a distributed network without having to tackle complicated DCOM settings.
Getting started is easy. File OPC Server is ready!
After the installation process you need to configure the OPC server. Please refer to the documentation.
