Description
FALSE
DONE = TRUE:
Job was completed without errors.
With read jobs ("COMMAND = W#16#0081 ...
008F"), this simply means that the transfer
between the optical reader and FB (CPU) was
error-free.
To find out whether the DMC processing was
successful, you will need to process bits
"READ" (bit 3), "MATCH" (bit 4) and "N_OK"
(bit 5) in the status byte of the optical reader.
FALSE
ERROR = TRUE:
An error has occurred.
