As we discussed in the first post of this series, the term "OPC client" often refers to off-the-shelf HMI or SCADA applications. OPC clients can also be other custom developed software applications in your enterprise that could benefit from access to OPC process data. Or there might be a new custom application you need to develop that requires access to OPC process data. In those situations, you need a reliable, straightforward method to enable those applications as OPC clients.
In Part 2 of our series on How to Develop Custom OPC Clients, we will cover step-by-step how to use low-code techniques to read, write and subscribe to OPC process data through building a basic OPC client application in Visual Studio.NET.
