Hello everyone. I am using CODESYS OPC UA Server and C# program in conjunction. There is no problem with one C# program accessing the OPC UA Server, If more the three C# programs access the OPC UA Server, data exchage become very slow. What should I do to make the speed of the OPC UA Server fast even if ti works with more three C# programs? If somone knows the answer please let me know. thanks Jooil
