Signal blocking facility

Signal blocking facility

Hi,
Some protection relays support a facility to block message in monitor direction and also in command direction. It will be useful in test conditions of substation because operator could prevent from sending signal to server and SCADA from protection devices but some relays do not have it.
Is there capability in zenon to define a similar blocking facility for devices that do not have above functionality independent of their protocols, for example preventing from polling selected device manually?
Thanks
