Hello

I am using Reporting on I/O fields in WinCC 7.5.2 and it is annoying for operators to click the “OK” button on “Please enter operator input message …” window.
I found the AckMsgInstComForce  function that seems to be perfect.

The problem is I cannot find it from Standard Functions and if I try to call it out it says it is not and a function.
Any help how to use the function or any other way to solve my “Please enter operator input message …”  acknowledgment issue? 
I still need the changes to be logged in long-archive list.
 

Hello Volli7,
the message is correct the funktion AckMsgInstComForce without any Parameters does not exist.

This Function has and need 7 parameters, which should be correct set. please look in the manual or the link which I added.

If it doesn't work with correct parameters, Open the global C-Editor select Options → regenerate Header and Compile all Functions.

If this doesn't help creat a new service request:

Thank you for your answer.
It compiled!!!

I will try to now make it work as well, but the changes are high that someone needs to bottle feed be the parameter values like to a baby goat.

Please do not refer me to "how to program in C in short 5678 pages manual".
But how do I read the return value of the function?
