The Right module on your picture is an output module.
It must be DO1 and not DI1

I know, it is just an example... terminal block was too big to fit on picture nomicons/grin

Ok, I found out that element is indeed replaced, but I have to reopen project to see changes. So far I have found no way how to update it in application. Anyway it works great, reloading is minor inconvenience.

That is a solution, unfortunately even with help of google translator I don't have slightest idea how to achieve it.
From what I've seen so far this is greatest issue of this program. It is best freeware for schematics by far, but quite inaccessible for non French speaker and newcomers in general.

Hello. In picture module on left is Custom master - Coil type. On right module is Slave, switch state: Other type. I'm happy with Slave having reference to master and Master having no switches references. But is there any way how to make reference to Slave in Master element, when Slave is not a switch like on picture? I mean directly in element, not using refmaster.emt and refslave.emt in folio.

Maybe I'm idiot, but both options - "make both elements coexist and "overwrite existing element" - have same result. New element is new and old elements stays same, not updated.
