Codesys - Updating Unused Variables

[uminded 0]

Is there a setting somewhere to get the UI to update unused variables? For example, I just need to troubleshoot an Ethernet/IP device I load up an empty project, setup the EDS and I want to view the data.

The bit mapping never updates unless I include it in logic.

The yellow highlighted items are not used in my program so they do not update. They may be diagnostics or error codes though that I want to see but not use.

SOLVED! : In the IO Mapping in the bottom right corner set “Always Update Variables”: Enabled 2 (always in bus cycle task)

Yup!  That is how you do it.

Another way to get values to show up is to just type the variable name somewhere in the code.

 

For example

Input_1;  

It will generate a warning  *This code doesn't do anything, is this intended?   or soemthing.

but who cares about warnings, only errors will stop me!
