TP1200 and 1513 CPU didn't communicate

Simulation works good connected to the real PLC, only real HMI is not able to connect, I already tried to change cables, ping from HMI, download HW config, download complete compiled program, connect directly from HMI to CPU. I believe something from configuration is still giving me problems. Is there any other point to consider? Thanks! ------------------------------------------------------------------------------------------ Split from TP1500 Comfort V2 and S7-1500 didn't communicate.

Also, could you please post some screenshot with your configuration? Did you try to create a new project from scratch and check if connection works? Br, Cocolino

This has a start and end Timestamp. Check the Time settings in PLC and HMI -> check and set the current Date/Time. Perhaps this could be a reason for this behaviour? Check also on the Panel if you can do a PINg to the PLC (you can use a commandprompt on the Panel) Bye Murof
