How the Remote Ack All connection works
When this connection changes to a new non-zero value, all unacknowledged alarms are
acknowledged.
Set up the data source to send a new non-zero value to the Remote Ack All connection
each time you want a remote acknowledgement of all alarms to take place.
How the Status Reset connection works
When the application starts, this connection has a value of 0. If a reset alarm status or
clear alarm history button is pressed, this connection is set to 1 for the hold time or for the
duration of the button press, whichever is longer. At the end of this time, the connection is
reset to 0.
The Status Reset connection is also set to 1 if the Remote Status Reset connection changes
to a new non-zero value, and remains set for the hold time.
While the hold time is in effect, the alarm status cannot be reset again. The status of
alarms keeps updating during the hold time.
How the Remote Status Reset connection works
When this connection changes to a new non-zero value, the status of all alarms is reset, as
described on page 9-9. Alarms can be reset using other methods regardless of this
connection’s value.
Set up the data source to send a new non-zero value to the Remote Status Reset
connection each time you want a remote resetting of alarm status to take place.
How the Close Display connection works
When the application starts, this connection has a value of 0. If the alarm display
(assigned in the Alarm Setup editor) closes, this connection is set to 1 for the hold time. At
the end of the hold time, the connection is reset to 0.
If subsequent alarms are generated, the alarm display opens again regardless of the Close
Display connection value or hold time status.
How the Remote Close Display connection works
When this connection changes to a new non-zero value, the alarm display closes. The
alarm display can be closed using other methods regardless of this connection’s value.
Set up the data source to send a new non-zero value to the Remote Close Display
connection each time you want a remote closing of the alarm display to take place.
