Binary Inputs (BI)
All binary inputs (BI) points have the following features:
●
Support Change of State (COS) reporting based on current state.
●
Support Change of State (COS) reporting based on alarm condition.
●
Support Change of State (COS) reporting based on override status.
●
Always considered reliable.
●
Overriding is supported from the standpoint that the “Override Active” bit will be set and the value reported to
the N2 network will be the overridden value. However, the value in the drive remains unchanged. Therefore,
the N2 system should be set up to disallow overriding BI point or have an alarm condition activated when a BI
point is overridden.
