• the IP addresses entered refer to actors with the role of interlock with respect to the current role
• the protections for which selectivity must be actuated by setting a mask, must be selected for each
interlock actor entered. Thus set, the function will now be indicated as logic in the following text so
as to distinguish it from the standard function, now also indicated as hardware in the following text
• thus selected, the protections add to those of the hardware S, I, 2I, MCR, G, D-Backward and D-Forward
• hardware selectivity only, or both hardware and logic selectivity can be selected
• diagnosis can be set, for each interlock release, to ascertain whether there is consistency between
the hardware and logic selectivity information
• a mask can be set for the purpose of identifying those protections whose received selectivity
information must be re-transmitted, regardless of whether the actor is in the alarm status. The
mask is only applicable to logic selectivity information
