Given in DW1, in the event of an error, is the number of the byte at which
the error in DB1 has occurred. For some errors, the address of the errored
block is indicated.
For the display of a DB on the PG, the data are not numbered in bytes but in
words.
If the CP 541 detects more than ten error messages, it ceases evaluation of
DB1.
For some errors, you receive multiple error messages. You should therefore
not consider each error message on its own but compare it to the other error
messages.
You have inadvertently entered station number 289 instead of 28, but you
have entered all other parameters correctly. You receive the following error
messages:
1704H: L2 interface not operational
2104H: TLN beyond permissible value range (1 to 30)
2204H: TLN of an active station is greater than HSA.
Up to 10 DB1 errors may be entered. The meanings of the error code and the
remedies can be found in Table 6-4.
Meaning g Remedy
Specify DB1 as the first entry in DB1.
Specify END as the last entry in DB1.
Specify ";" before END.
Or check the DB1 format.
Verify the structure of the block designator and
fully specify all parameters.
