So the automatic external mode is run by means of PGNO_VALID.
So the PLC sends a program number to the KUKA controller... the controller sends the program number back to the PLC... you compare the two numbers and if they are the same you can trigger the PGNO_VALID... after that the program will start.
That is not an error... its a normal message... the controller is just waiting for you to trigger the PGNO_VALID bit.
Maybe something on the PLC program side is messed up... look into why it is not sending the PGNO_VALID.
Lookup documentation on automatic extern. How to find documentation is already explained in the previous thread you opened.Posting the same question multiple times usually not helpful.

first of all this is not an error. it is message informing you what is robot doing. and it is running.... but to proceed it needs to get valid program number from PLC. so it waiting for PLC to send correct handshake signals that tell to robot "here is the program number" and "program number is valid, you can read it right now". if the system was working before, this probably means that PLC is not ready or not running.
