Job, global part
The results are written by the PLC operating system; therefore, these signals can only be
written by the user.
If the job was completed without errors, the "Job completed" signal V1200 2000.0 is set to 1.
If an error occurs while executing a read/write job, the "error in job" signal V1200 2000.1 is
set.
The result signals in VB1200 2000 are global bits for the whole job. Possible error causes
can be here, e.g.:
● Number of variables (V1200 0001) outside of the valid range
● Variable index (V1200 1000) outside of the valid range
After evaluating the result, the "Start" signal (V1200 0000.0) is reset by the user. The PLC
operating system then resets "Job completed" or "Error in job".
