Write Job Status - Siemens SIMATIC S7-300 Manual

Programming the FM 354

Write job status

The status of a write job is indicated in the user DB (in data byte DBB1).
Table 6-2 Write job status
Bit in JOB_WR
(DBX1.)
.BUSY, 0 = 1, write job busy
This bit is set by FC MODE_WR as soon as it starts processing a write job
(JOB_WR.NO > 0 and bit 2 in JOB_WR.IMPOSS = 0).
This bit is cleared by FC MODE_WR as soon as the write job has finished running
(JOB_WR.NO = 0).
.DONE, 1 = 1, write job finished
This bit is set by FC MODE_WR as soon as it has finished a write job
(also with error and unknown job)
This bit is cleared by FC MODE_WR when a new write job
begins. You can clear this bit manually
.IMPOSS, 2 = 1, write job processing is not possible in this cycle:
–
–
–
–
In this case, you can leave the write job (JOB_WR) or
delete it. FC MODE_WR clears the bit when all the above conditions have been met.
.UNKNOWN, 3 = 1, write job unknown
The write job (JOB_WR) which you specified is not within the known range
(see error evaluation). FC MODE_WR clears this bit as soon as JOB_WR contains
a valid number. The unknown number is retained until then.
.MODE_BUSY, 6 = 1, when a mode/movement is started with the appropriate control signals or
on a BL = 1 checkback (busy).

.POS_REACHED, 7 0 = on the checkback POS_ROD = 0 (position reached, stop) or when a mode
is started with the appropriate control signals.
