Hello djpiky, Do you have SIMATIC NET installed and if so, which license do you use? For more than 8 S7 connections, the SOFNET-IE S7 license is required.

Hello djpiky Check the communication ressources of your S7-1200 PLCs. the older ones do have problems connecting multible HMI Systems.Do you have another HMIs like Panels connected to this PLCs also? If yes disconnect them and look if this connection is stable in WInCC... https://support.industry.siemens.com/cs/ww/en/view/109479986 Bye Murof |
