Hello Everyone.
I have a Chocolate tempering machine That have a Micrologix 1400 CPU and a Panelview 7 HMI.
I'am trying to create a PLC logic where when one of the HMI String display value goes above 0.2 Celsius than the setpoint turn on a output.

The actual value tag of HMI is {::[Beta]N23:0}/10 and
The setpoint value tag of HMI is {::[Beta]F31:3}

The issue is actual value tag of HMI ( {::[Beta]N23:0}/10 ) is not present in PLC program. Do you guys have any idea why?
please note that there are no other PLCs or HMIs in the system.

An easy mistake to make. In FTView, the "Tag / Expression" field often contains math operators which can look like address syntax elements.

Thanks for posting the followup !
