• The DO Timer column refers to the time [in seconds] that the Digital Output is to be active. The DO
Timer box will display “n/a” when Digital I/O is selected.
Alarm Events Panel (Digital Output Only)
The color of the response channel in the “Alarm Events” panel indicates the limit/alarm status that will
cause the switch to change status, i.e., from Opened to Closed, or visa versa. Click on a channel number
until the desired limit color is displayed. If the relay is normally Opened when monitored data causes the
specified limit/alarm, the relay will change to Closed for the duration specified by the timer; then it will
return to the normally Opened status.
Note that you can have the system count the number of consecutive alarms and change the relay status
when that number of alarms is reached.
Action Performed Panel (Digital Input Only)
This panel consists of a pull-down list that allows you to select one of several “actions” for Digital Input
applications.
Possible actions are:
• Store Snapshot
• Change Acquisition State
• Change Limit Check State
• Increment Serial Number
• Increment Serial Number and Reset Peak Hold
When you click the Save button, any of the unchecked check boxes for relay channels
will close and stay closed until the condition is met for that relay channel. If you have
something that will actuate when the channel closes, it will do so as soon as you click the
Save button.
