Hi, You have 2 ways to force screen : 1 -From PLC : Declare Job mailbox area in Connexion menu and force screen from PLC using function number #51 according to IO adress bit value. 2 - From HMI: - Create a tag who is linked to your PLC IO bit (MyTag). - Create a script in which you test MyTag to 1 (ForceScreen()) :
- Into Tag table -> Click on MyTag -> Go to Events tab -> Under Change value, click on Drop down box and select VB functions ChangeScreen. Regards. AttachmentHMI-Area pointer-Job Mailbox.pdf (209 Downloads) |

Hi Murof, I thought about the second option of the FAQ but, when value change from 1 to 0, Event is trigged again and screen is displayed again. RetroK want tp show screen only if IO bit turn ON. Regads |
