Instructions:
Proceed as follows to configure screen selection via the controller. At the end of this entry is a free download of a sample program.
 
No. Procedure
1 Create area pointer:
In ProTool you create the area pointer "Interface Area".
The length of 16 words is preset.


Fig. 01

2 Structure of a PLC job:
A PLC job consists of 4 data words. The first data word contains the job number. Depending on the function, up to three parameters are transferred in data words 2 to 4. The figure below shows the principle structure.

Detailed information on the topic of area pointers and setting the separate parameters is available in the manual SIMATIC HMI Communication, Appendix B,  "PLC Jobs".
The manual is available in Entry ID 1137086.

3 Functional sequence:
If the first word of the job mailbox is not equal to zero, the operator panel evaluates the PLC job. The operator panel then resets that data word to zero. For this reason the parameters must be entered first in the job mailbox and only then the job number.
4 Sample program:
FC1 coordinates the PLC job. DB51 is the interface block in this case. Using the marker 0.0 "Start_select_screen" you can trigger screen selection once
of "Screen 1" with a positive edge. The marker is reset by FC1.
