Comparing Two Different Implementations of OPC UA Clients

In this paper, a comparison of communication solutions between a programmable controller and industrial controller devices is presented. The study was conducted through a project in which is investigated and developed methods for Open Platform Communication (OPC) client to programmable controller efficient, reliable, real-time communication. The proposed for investigation approaches rely on C# OPC client implementation and the Node-RED platform, maintaining goal in achieving the same functionalities. The first method involves using libraries to create functions for establishing a connection with the server and managing the obtained data. The second method involves using an API and several associated tools.
