TIP: To enable the server feature it is necessary to set the property “Operate as OPC UA server” (project tree.. HMI > Runtime settings > OPC UA Server). Through other properties in the same place, it is possible to adjust the level of security and performance. You can use UA Expert client to check the funtionality: https://www.unified-automation.com/downloads/opc-ua-clients.html Sample project Attachment Project118_20221230_1327.zip (563 Downloads)
