Hello,

Now, I'm face a error when migrate WinCC Flexible program to TIA Portal V15.1.

When compile my migrate project, this error occurred " The parameter of a function is not available for trigger m70, event 'Value change'. Tags of this data type are not allowed for this parameter.,,,12:40:35 AM "

Once, this error not occurred in TIA Portal V13 when compile this project. However, in my project, I use TP1500 Comfort V2 (6av2124-0qc02-0ax1), this hardware can not declared in TIAportal V13. So, I use TIAportal V15.1.

Anyone, can solve me this error. I need your help.

Thank you all.

Hi Tin,

Welcome to the forum!

This field must not have a TAG, but it is a configuration field. 

Ok. Disable this Event in my project. It's fine.

When I read the Event Manual, I known that it was to change the HMI device status (Online, Offline & Load/Transfer). In project, I did not see that this function being used.

I don't know why I did not get this error with V13?
