[?]: How to select screen in ProTool using Plc Job 51?

[venix]

Hi! Can someone tell me how to select screen using plc job 51 in protool?For example,if a memory bit is set I want to call a function wich shall do Select screen job 51.My PLC is C7-633.I set up Interface Area on DB 11,and I made this data block also in Step 7 Blocks.I create a function like in the documentation :
OPN DB 52 (in C7-633 is CALL in place of OPN but this is wrong I think because it appears in red)

Code: Select all

L  9
T DBW 6
L 5
T DBW 8
L 1
T DBW10
L 51
T DBW4

Even so,I get the red SF Led and my CPU is going in Stop mode.
Best regards!
