Enable this alert for loops where the
execution is critical. If the AO or DO
block is not scheduled, or scheduled
incorrectly, it will trigger an alert after the
Timeout Alert Point has been exceeded.
Set the Timeout Alert Point to a value
between
a. 30 seconds and
b. the maximum time before a user
should be notified. The minimum number
depends on the time it takes for a host to
download a configuration to the device.
Shutdown can be enabled if it is desired
to move the valve to the Zero Power
Condition at the same time that the alert
is generated.
