[?]: Sticky keys ( Memory bits ) in TP177B WinCCFlexible

[Sundar]

Hello Guys,

Please help me to solve the below problem.

We are using a TP177 B connected in profibus DP and CP317- 2DP CPU in our project. There are few Plus & Minus buttons in touch panel for setpoint value to drive inverters.

The problem is the tags assigned to these plus , minus buttons are not stable , Example it give continuous signal ( sticky even we removed the finger from the touch panel ) to PLC and leads to unexpected result.

We are using winCCflexible SP1 HF2. Even in WinCCflexible runtime screen also produces this kind of error.

Somebody may face similar problem !
