PLATE 1186323 - Caterpillar

Failure Mode Identifier (FMI)
The "Failure Mode Identifier" (FMI) configures what type of failure an event will represent. A technician can configure any FMI for any SPN, but discretion must be used. Certain combinations may not be useful. That is, the OCP may not be configured to display or trigger a response for certain combinations of SPN and FMI. As an example, a fuel level SPN with a "Condition Exists" FMI is not meaningful. The "OCP" can be configured to display or react to only low fuel level or high fuel level warnings or shutdowns.Configuring Relay Outputs
Illustration 8 g02279879All eight relay outputs have identical parameters and options. The configuration for "Relay Output #1" is shown in Illustration 8. To configure the DIO to trigger an output that is based on an event, on the data link related to a specific SPN, the SPN must be selected while the following dialog is open. Refer to Illustration 8.The "trigger condition" is a list of conditions that will trigger an output. For the conditions labeled "specific event", the relay will be activated upon receiving a category of events. The events can be either a single FMI or a set of FMIs. The event must be an FMI for the SPN that is selected.For the conditions that are labeled "General Event", the relay will be activated upon receiving a category of events. The events can be either a single FMI or a set of FMIs for any SPN. In the "General Event" application, the DIO module will ignore the entry in the SPN parameter.If the "Disabled" condition is chosen, the relay output will not be active for any condition.The Suspect Parameter Number (SPN) is a choice from a predetermined list of SPN's that are supported by the DIO module. If you wish to configure the DIO to trigger an output based on an event on the data link related to a specific SPN, the SPN must be selected here.
