However, because of the massive amount of legacy hardware still in operation, knowing how to work with OpcNetApi.dll remains a highly valuable skill for industrial software engineers. OpcNetApi

By referencing OpcNetApi.dll and its companion, OpcNetApi.Com.dll , developers can use standard object-oriented patterns to browse tags, manage groups, and process data. Common Implementation Workflow difficult to debug
