Switch incident resolution

Ability to distinguish between multiple contact successive changes:When any two contacts displacement interval is greater than 1
ms,Ability to distinguish between cells (less than 2ms) can be reflected in the SOE.

Signalling scanning speed

All channel scanning cycle time required is 1ms

/

Remote signaling debounce time

All channels use the same debounce time 1ms (can be set)
