Title: Not getting ValueChanged event for float values
Post by: mlefebvre64 on March 14, 2025, 08:21:34 AM

Seeing a problem I haven't run into before.
Using the EthernetIPSLCMicroCom driver to communicate with an Allen Bradley Micrologix 1400.
The version of AdvancedHMI I am using is AdvancedHMIv399xR1.
The project is in Visual Studio 22. I have added a project into the AdvancedHMI solution that I use to output the values.
 
The problem I'm seeing is I have several BasicLabels addressed to read Integers, Binary, and Long registers that are updating whenever the PLC value changes, but any BasicLabel addressed to a float is not receiving the value or the ValueChanged event.

If I change the BasicLabel to read an Integer value it updates properly.

I compile with just the AdvancedHMI download and it updates in the MainForm from the float address properly.

Any suggestions of what I might look for that would cause only the float values to not update?
Thanks in advance.

mlefebvre64 you should consider switching from AdvancedHMIv399xR1 to Beta version.

bachphi might suggest what version he is using.

Thanks for the replies.
I have used this R1 version several times in the past reading floats successfully.
Wasn't sure if it had anything to do with Visual Studio 2022 which is different from past implementations.
I am putting the value into a long and using format and scale to display it correctly.
Will try a beta version.
Thanks again.
