Dear All,

HMI: KTP 700 Baic, PLC, S7 1200 CPU

HMI Connections: 4

Functionality:

When user click on any button on HMI (Event setbit, M2.6), then screen will move to Screen num 3 using Job mail box in PLC ladder. PFA zip file.

But when I click button on HMI (Event setbit, M2.6), the conditions in that rungs gets works well like ADD, SUB, Timer ON,SET, RESET but values in MW800 (Jobmailbox) & MW802 not get move sometimes. So that screen not get switch.

Sometimes it moves.

This I cause repetitive click on HMI.

Please anybody have solution pls suggest.

Thank you #dP

It is by default 1 second.

If I change it to '100 ms', will it eliminate the issue?
