Requesting program selection
DB19.DBX13.7 = 1
Program selection: Acknowledgment interface
Job acknowledgment
● DB19.DBX26.7 == 1 (selection identified)
● DB19.DBX26.3 == 1 (program is selected)
● DB19.DBX26.2 == 1 (error when selecting the program, see error ID DB19.DBB27)
● DB19.DBX26.1 == 1 ((job completed)
Error detection
DB19.DBB27 == <error ID>
Error detection
Value
Program selection: Job processing
A job to select a program is executed as follows:
1. Checking the acknowledgment byte: DB19.DBB26 == 0
If the acknowledgment byte is not 0, then the last job has still not been completed.
2. Specifying the program list: DB19.DBB16
3. Specifying the program number: DB19.DBB17
4. Setting the request to select a program: DB19.DBX13.7 = 1
5. Evaluating the acknowledgment and error interface: DB19.DBB26 and .DBB27
The order is still not completed on the HMI side as long as: DB19.DBX26.3 == 1 (active)
The order has been completed on the HMI side if one of the two signals has been set:
- DB19.DBX26.1 == 1 (OK)
- DB19.DBX26.2 == 1 (error)
