S Job request status
You can read the status of the job request in return value RET_VAL and in the
"Write/read job in progress" signals in user data block AW-DB (DBX68.0 and
DBX68.2). You can evaluate the status of an individual job request by evaluat-
ing the Initiate, Ready and Error signals for that job request.
Table 6-2 Job request status
Job Request Status
1. Job in progress
2. Job terminated without

3. Write job terminated with
error in this job
4. Write job aborted or not
executed
5. Read job aborted
6. Write and Read aborted
or not executed (in the
case of simultaneous job
requests)

= TRUE; Write request cannot be serviced in this cycle because:
S
The axis is not initialized
S
Test mode is enabled
S
No operating mode is active
S
The selected operating mode has not yet been set
In these cases, you can leave the Write request pending or you can cancel it.
The POS_CTRL block resets the signal when all of the above-listed condi-
tions are fulfilled.
= TRUE; Read request cannot be serviced at this time because:
S
The axis is not initialized
S
No mode has been selected
S
Test mode is enabled
In these cases, you can leave the Read request pending or you can cancel
it. The POS_CTRL block resets the signal when all of the above-listed condi-
tions are fulfilled.
With this signal you can reset all Ready and Error signals prior to processing
of the pending job requests. The signal itself is then reset by the block.
