WagoAppPowerMeasurement sample app Unresolved reference when using 750-495 function blocks

CODESYS
1

I’m trying to push a program that uses the function block for the 75x-495 module included in the library WagoAppPowerMeasurement but when I instanciate the block FbConfigurationAndStatus_495 I have a error message telling that there is 1 unresolved reference.

It is also happening when i’m use the block FbConfigurationAndStatus_495_040_010.

After the download, the plc falls in error state and logs me out.

Here is what I have in the messages window :
[FATAL ERROR] Unresolved reference: ‘FUIODRVCALCULATESLOTNUMBER’

And Here is what I have when i read the logs from the plc :

Could not link external function FUIODRVCALCULATESLOTNUMBER

Does anybody have a clue of what is wrong?

Hello,
What is the PLC, Firmware and codesys number ?
It seem you have a miss match libraries / Firmware.

Hi,

It was indeed a firmware vs library issue and seems to be fixed right now.

We were also not using the blocks like it should, but wago support put me in the good trail!

Thanks for your reply,

Francois
