Problem with interlocking

Problem with interlocking

Hi, i want to solve a problem that we have with the interlocking, and perhaps you have an idea. We have several screens that are identical and each screen communicates (its variables) with a different RTU. For each screen we only change the variables with a function but the symbols used are the same.
We want to configure an interlock for several symbols in each screen. (Local status of the RTU) that disables all commands. This is possible for one screen, but for the others (with same symbols) it is not possible to configure a different interlock.
¿How can this be done?
Regards.
