Set up for Alarms to Execute Commands
Use the following procedure to set up alarms to execute commands:
1. Use the “Set up Alarms to Execute Commands” menu items (see table below) to
define up to 3 sets of alarm actions. Each alarm action set consists of a pair of
commands, one to be executed when an alarm is activated and one to be executed
when the alarm is cleared. Defining the alarm action set makes the command pair
available to assign to an alarm.
2. To assign a command action set to a process measurement alarm, you must have
set up the measurement (see Chapter 4) and have assigned an alarm to the
measurement (see page 6-5). Then the alarm action set will be added to the list of
alarm indicators in the “Set up Alarm” menu items.
3. To assign a command action set to a fault, warning, or mode alarm, use the menu
items described in the “Assign Relays to Fault, Warning and Mode Alarms”
section on page 6-6.
Note: Write down each of the command action sets as you specify them. Due to
the limited display space, the “alarm indicated by” selection in the “Set up
alarm” menu item can not display the full command name. The alarm
action sets are referred to as “#1 act on ALM action,” and so forth.
