Hello, I have the same exact problem: the SetBitWhileKeyPressed function get stuck after the button is no longer pressed. I am on TIA V16 Update 5. The issue happens rarely, but it does, and it would damage the machine. Also, we cannot afford to stop the machine with the emergency every time this happens. Might the communication channel be overloaded? Or else? ------------------------------------------------------------------------------------------ |

Install the Update 6 for TIA V16. Maybe it helps. Updates for STEP 7 V16, S7-PLCSIM V16 and WinCC V16 |

Hello It depends also which type of PLC you use. for example a S71200/1500 has a compleate different timing in HMI communication than a S7300 for example. in the new PLcs the HMI Communikation is a compleatly parallel task. (for example: LINK) this could lead to the mentioned behaviour if you for example use In/out parameters or FBs. this could lead to overwrite problems. -> LINK Bye Murof |
If this Information really helps, you could use the Rate function |
