4. Under Alarm Lists, specify:
Clear Lists on Powerup
Select this option to clear all entries in Alarm Lists
when the terminal is reset or power cycled.
Size
Specify the maximum number of alarms to store in
the Alarm List. Select a value between 1 and 100.
The default is 25.
The maximum number of alarms actually stored
depends on nonvolatile RAM available in terminal.
5. Under Print Items, select the data to print with alarm text when:
•
Print Alarm button is pressed
•
Alarm is configured to automatically print when triggered
•
Print Alarm List button is pressed
The print items are:
•
alarm date
•

The items are printed in the order listed, with the alarm text
appended to the items.
To print alarms, your terminal must be equipped with an RS-232
printer port.
6. Under Time Values specify:
ACK Hold Time
Length of time the terminal holds the trigger value at
the address defined by the Acknowledge tag. The
hold time should exceed the scan time of the
controller to ensure that it is read at least once.
Hold time values are 0, 50, 250, 500, 750, or 1,000
milliseconds. The initial default is 500.
Snapshot Timeout
Length of time the terminal waits for the controller to
complete I/O scans when an alarm is triggered.
If the message contains embedded variables, the
controller may have to complete several scans.
Variables appear in the alarm message as ???? until
the data is read. If the data is not read before the
timeout occurs, the variable appears as **** .
The timeout is entered in seconds. The initial
default is 2 seconds.
