Scenario and conditions

  1. is it possible to have condition for switching ON a relay?
    ie, if relay 1 is ON and relay 6 (an other module) is ON then switch relay 3 ON?

I think it’s not possible, so a piece of software is needed, right?

  1. So, if I want to use VMB8PB or VMB4PD to act with condition, the relay should react to virtual addresses of PC messages…
    ie, VMB4PD = address 2, if push button 1 is pressed, I want to activate Relay 3 if relay 1 is ON.
    VMB4RY = address 3 should react to simulated VMB4PD address 4, right ?
