Water Temperature parameter, you would then get an alert every time the ignition was switched off and the engine’s ECU stopped transmitting data.
8.3.7.3.1 Trigger Configuration
Figure 260 – Trigger Configuration – Data Unavailable Alert
Alert Set Delay – If a valid value for the parameter being monitored is continually not received or has an invalid value for the amount of time specified in this field, the alert will become active.
Alert Clear Delay – The parameter being monitored must continually be received with a valid value for longer than the time in this field in order for the alert to become inactive.
8.3.7.4 Trigger Type is On Alert
As opposed to high and low alerts that are associated with analog input signals (i.e., many different possible input values), there are also switch alerts that are associated with a binary input value (sometimes called on or off, yes or no, enabled or disabled, set or reset, active or inactive). The switch alert is similar to the high and low alert except that there are no set or reset points. The mere fact that the switch is seen as On causes the alert to become an active alert (assuming the Set Delay is set to zero). Likewise, if the switch being monitored is seen as false (i.e., binary 0), then the alert becomes inactive (assuming the Clear Delay is set to zero). If the delays are not programmed to zero, then the switch must remain On for the Set Delay before the alert becomes active, and must remain Off for the Clear Delay before the alert becomes inactive.
