\*\* Summary\*\*

Be able to see the current value of the register variables in the IO Setup tab.

\*\* What is it?\*\*

\*\* Why is it needed?\*\*  
It would help during commissioning when programming with the PLC. Currently what I do is to create a script with all the variables and read them continuously. After that I can see their value in the program tab variable list.

It would be nice to have this by default in Polyscope
