Use code boxes.
On a cursory examination, P00.SRC does not appear to be called. So we can probably ignore that module entirely, since none of its subroutines are DECL'd Globally.
Mercedes appears to have substituted their own modified copy of P00 but called by the SPS, P00_SUBM. Which the SPS has multiple calls to.
You provided no data on the setup of the various PGNO variables. But the message you listed in the first post only occurs at lines 176 and 205 of P00_SUBM. Line 176 only executes if PGNO_VALID is a negative number, and 205 if PGNO_VALID is a positive number.
Going by your photo in post 4, PGNO_VALID is 3206, and the photo from Post 3 shows that Input 3206 is not coming on. So either your PLC is not sending that signal, or your IOSYS mapping is incorrect.
I think my setting should not be a problem because post 1 is the PLC interface PGNO_REQ has been invited Post 3 shows that bit1 and bit3 have been accepted My PGNO_TYPE is 1 According to the data provided by KUKA that is 8+2=10 and my PGNO_FBIT is 16#0A is also 10
Do you mean that I can not use REFLECT_PROG_NR?
