67
Selects the action type that will happen when an out-of-limit condition occurs. 3 types are available: Major alarm,
Minor alarm, and Command (CMD). On CMD, no alarm will be triggered. Use this Action when you want to take
actions without triggering any alarms.
4 –
QUALIFIER AND QUALIFIER STATE or DATA
Qualifying element (operand) which can be any input, output, flag, timer, SNMP GET, Logic Gate, etc. Essentially
any ID in the Cortex can be used to mute or unmute the input to prevent it from taking any action. When the Qualifier
is active, the input will be monitored and be able to generate alarms. When the qualifier is non-active (or normal),
the input will be muted and it will not be able to generate an alarm. To invert the Qualifier’s level, simply put a ! in
front of its ID. For example, use !1D01 to invert it. Leave the Qualifier field blank for a “don’t care” condition.
STATE (default setting): the State (Normal or Active) of the input being qualified can change only when the Qualifier
is active. Readings from the input (Current Value) continue to be updated periodically independently from the
Qualifier state.
DATA : Same as the STATE mode, but in this case the readings from the input (Current Value) remain frozen at
their latest values, as long as the Qualifier is not active. This mode is used like a “Sample-and-Hold” for the readings
from the input.
5 – SOURCE ID
The identifier of the input on which activity monitoring will be performed (Metering, Status, etc…)
6 – CONTROLLED OUTPUT
Outputs to be controlled (on/off) based on the state of this input. The two output types allowed are relays (both
physical and virtual) and SNMP SETs. For the relays, adding a P suffix will Pulse the relay (ex: 1R01P), L will Latch
it and R will Release it.
7 – ALARM MODE – CONSECUTIVE or CUMULATIVE
Method used for the time-based activity / inactivity alarms of the Status inputs. The calculation method takes into
account the Maximum Activity Time value and/or Maximum Inactivity Time value (see #7 and #8 below).
CONSECUTIVE (default): Timer counts the amount of time the input has been at its current level. It resets every
time the input level toggles.
CUMULATIVE: Timer cumulates the amount of time the input is active. An alarm is set if this cumulated time
exceeds the threshold (more detail below).
8 –
MAXIMUM ACTIVITY TIME
Total amount of active time that must be reached by the counter before the Timer is turned on. A time value of 0 to
9999 minutes can be set. Default setting is 0, for which no automatic action will happen.
9 – ENABLE
Enable / disable the input. Useful to deactivate an input, without losing all its settings, when the input is causing
intermittent problems or nuisance alarms.
10 – SYSTEM LOG
Log (or not) the input’s activity in the System Log. Useful when inputs do not need to be logged, but are required
for day-to-day operation.
11 – COUNTER
The counter starts counting as soon as an input becomes active, and stop counting when it becomes inactive.
LOG DAILY ACTIVE TIME
Log the daily active time in the System Log.
RESET AT MIDNIGHT
Reset counter at midnight every day.
12 – RESET COUNTER
Manual counter reset.
13 – RESET TRIGGER
Operand-based automatic reset. Reset can be generated automatically by any input ID in the Cortex.
14 – LAST RESET
Date and time at which the last reset occurred.
15 – REFRESH / READ
Refresh / read the screen content.
16 – SAVE / WRITE
