Technical data

Note
If the job type "0" is set in the data field and all other parameters
are
"F" or "FF" (hexadecimal) when you read out a timed job,
then
no timed job is active.
This status can occur as follows:
a) following a COLD RESTART, when no timed job is generated,
b) when a timed job programmed to be executed only once has
been executed
or
c) when you have cancelled a job.
Possible errors: In the event of an error, OB 19 or OB 31 is called. If OB 19 or OB 31
is not loaded, the CPU goes to the stop mode.
In both cases, error IDs are entered in ACCU 1 and ACCU 2 (see
following table).

already been generated, the error identifiers are transferred as

however, the previously generated timed job
is retained.
