<div class="markdown_content"><p>Hello there,</p> <p>I have to send my variables that are in a GVL block to an external management system.</p> <p>These variables must be able to be written, same with another group of GVLs that must be read</p> <p>I give an example with TIA PORTAL from siemens<br/> On TIA PORTAL I can go to the properties of a DB, uncheck the compressed variables and the various offsets of the variables appear.<br/> 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.</p> <p>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? </p> <p>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?</p> <p>Thank you very much</p></div>
