Hello

I had a PLC S7 214 and k-TP178 micro in a system. Something went wrong and I had to buy a new PLC of the exactly the same type and reprogram it to perform the same function as before and the system is now back to normal. The problen I have now is with the hmi device. It is only showing #### everywhere. What could be wrong? The hmi is firmly connected to the PLC.  Thank you for your help

 Hello,

Usually with this #### you not have communication between PLC and panel, check connection or communication port of PLC.

You were sure before you had problems with the PLC, or even before it was #### ?

Thanks for the reply. 

It was perfectly ok before I changed the PLC. It all started after I replaced it. I will check communication ports but it there anything I should do before I connect the hmi?  I tried to click on transfer on the hmi screen but it's asking me to enter password if I want to change chanel
