Hello there,

I have to send my variables that are in a GVL block to an external management system.

These variables must be able to be written, same with another group of GVLs that must be read

I give an example with TIA PORTAL from siemens
On TIA PORTAL I can go to the properties of a DB, uncheck the compressed variables and the various offsets of the variables appear.
I communicate the slot and rack data and my job is done, the owner of the management software is able to communicate and take variables and write without problems.

Here on codesys I have seen that on properties of a GVL block I can uncheck the compressed variables, but how can I get them?

I don't see any offset of the variables, I can't see any racks and slots, surely there is another method, can you tell me?

Thank you very much
