VFD(Communcation cards)-20 VFDS 3.After that HMI we found communication cards are burn from surge-20 cards gone. we replace with new one. But HMI still shows ### MARKS. Can we check HMI Cimmunication working or not?

(Perhaps you can have a look at the Alarm table and search for System alarms, it shows if there is a connection or disconnection) All I/O fields show ###? How is HMI connected to CPU? (Profibus, Profinet) What happens when you connect HMI to CPU without anything in between? Best regards, Wizard
