The deployment of the request interface takes place at the following sequence:
1. Edit the following input parameters:
Name Data type Address (DB) Default Comment
JOB_REQ BOOL 4.3 FALSE Initiates the job (edges 0-1) *
JOB_ID WORD 6.0 0 Job ID:
00h Job without function
01h Writes the count value
02h Writes the load value
04h Writes the comparison value
08h Writes the hysteresis
10h Writes the pulse duration
20h Writes the end value
82h Reads the load value
84h Reads the comparison value
88h Reads the hysteresis
90h Reads the pulse duration
A0h Reads the end value
JOB_VAL DINT 8.0 0 Value for write jobs
*) State remains set also after a CPU STOP-RUN transition.
2. Call the SFB. The job is processed immediately. JOB_DONE only applies to SFB
run with the result FALSE. JOB_ERR = TRUE if an error occurred. Details on the
error cause are indicated at JOB_STAT.
Name Data type Address (DB) Default Comment
JOB_DONE BOOL 22.0 TRUE New job can be started
JOB_ERR BOOL 22.1 FALSE Job error
JOB_STAT WORD 24.0 0000h Job error ID
0000h No error
0121h Comparison value too low
0122h Comparison value too high
0131h Hysteresis too low
0132h Hysteresis too high
0141h Pulse duration too low
0142h Pulse duration too high
0151h Load value too low
0152h Load value too high
0161h Count value too low
0162h Count value too high
01FFh Invalid job ID
3. A new job may be started with JOB_DONE = TRUE.
