Using a digital input configured with the feature DIF.2001 -
“Command for resetting
alarms
”. When the input becomes active, the controller executes a reset of all
anomalies.
When the controller performs an anomaly reset, it also activates for one second the
outputs configured with the function DOF.3151 -
“Reset of the anomalies”.
This helps in
using the reset command of the controller for resetting alarms on external devices.
All anomalies are being recorded (each with its own code) in the events log.
There are some functions available for configuring the digital outputs related to anomalies:
•
DOF.4001 -
“Warnings”. The output is “active” if there is at least one warning or one
latched warning active.
•
DOF.4003 -
“Deactivations”. The output is “active” if there is at least one deactivation
active.
•
DOF.4004 -
“Alarms”. The output is “active” if there is at least one alarm (block) active.
•
DOF.4005 -
“Alarms and deactivations”. The output is “active” if there is at least one
alarm (block) or one deactivation active.
In addition, the controller makes available the anomalies statuses for the AND/OR logics by
means of the following internal statuses:
•
ST.006 - "Alarms acknowledgment in progress".
•
ST.007 - " Alarms reset in progress".
•
ST.008 - "Warnings".
•
ST.009 - "Latched warnings".
•
ST.010 - "Deactivations".
•
ST.011 - "Alarms".
•
ST.012 - "Not recognized warnings".
•
ST.013 - "Not recognized latched warnings".
•
ST.014 - " Not recognized deactivations".
•
ST.015 - " Not recognized alarms".
NOTE:
since we cannot define in advance neither which digital or analogue inputs (those from
the controller or from the additional modules) will be used, nor what function will they perform,
the list below refers, as an example, to the parameters of the first configurable input. The
symbol
(*)
or the
indication “or equivalent for the other inputs” next to a parameter show that
the same varies according to the input configured.
