Connect to Prosys Simulation Server

Developed by Prosys, the Prosys Simulation Server is a sophisticated OPC UA server that serves to replicate the behaviors of OPC UA devices and systems.

To establish a seamless connection with the Prosys Simulation Server using EMQX Neuron's OPC UA driver, it's essential first to switch the Prosys Simulation Server to Expert Mode. This can be done by selecting Options -> Switch to Expert Mode from the menu.
