The problem is that the PLC has its own OPC-UA server. I am including pictures from my attempt. It seems as though the Forte server’s nodes have numeric ID , whereas Siemens’ are a string. Image 1 How do I declare the endpoint URL on the Client's FB ID to connect this variable on the Siemens PLC? Endpoint Used: opc_ua[opc.tcp://172.21.5.1:4840#/Objects/3:plcMagazineBack/Outputs/xG1_MB20] Image 2 Attachment images.zip (27 Downloads)
