7.3.6.4 Alarm Mode
Each individual relay can operate in one out of three modes, by setting
the [Alarm Mode] entity to either [PV Monitor], [Remote Control], or [Not
In Use].
7.3.6.4.1 PV Monitor
In [PV Monitor] mode, each individual FII-DO-relay unit can monitor the
Primary Value (PV) or Secondary Value (SV) of another board
connected to the CAN bus, and either activate or deactivate the
associated relay if a certain condition is <True> or <False>.
☛
If [Remote Control] or [Not In Use] mode must be selected, skip to
section 7.3.6.4.4 and 0 respectively.
☛
From the [Alarm Mode] menu, select [PV Monitor].
☛
Select [Monitor Board ID], set proper value.
☛
Select [Monitor Board Instance], set proper value.
☛
Select [Monitor Function Instance], set proper value.
☛
Select [Monitor Source], select either <PV> or <SV>, as desired.
The [Monitor Board ID], [Monitor Board Instance], and [Monitor Function
Instance] entities determine the location of the entity to be scanned.
The behavior of each individual relay in PV Monitor mode is further
controlled by the [Monitor Mode] and the [Status Behavior] entities; see
next.
7.3.6.4.2 Monitor Mode
The [Monitor Mode] entity can either be set to [Remote] or [Local].
If the [Monitor Mode] is set to [Remote], the alarm status of
the scanned PV or SV is monitored. The alarm status is
compared against the value set in the [Remote Threshold
Source] entity. The [Remote Threshold Source] entity can
be set to <HH>, <HA>, <LA>, or <LL>.
Example: If the [Remote Threshold Source] is set to <HH> and a High
High Alarm occurs, the relay will be activated. It will not be activated by
any other alarms.
