Greetings!
I have the following problem.
My plc and my Hmi do see each other in the profinet network in which they are placed.
Likewise, my PC has the same IP address range. so that when i do ping the ip address of the plc and the hmi, if there is good communication.
The problem is that when you want to load some modification on the hmi screens, it simply doesn't allow it and this error appears.
only with the hmi. When loading the plc this problem does not appear.
Does anyone know how it can be resolved?
I use Tia portal 17
Yesterday I was still able to load settings on the hmi screen without problems and today it just didn't allow me anymore.
(no changes were made to the program from yesterday to today)
Thank you!
