Output Module faults are reported to the user through visual indicators on the Front Panel of the Module and through status variables which may be automatically monitored in the application programs and external system communications interfaces. There are generally two types of faults that must be remedied by the user: external wiring and Module faults. External wiring faults require corrective action in the field to repair the fault condition. Module faults require replacement of the Output Module. 5.2. Field Wiring Faults By measuring the output channel voltage and current, the Module automatically detects field wiring and load faults. When a field signal fails open circuit, short circuit or there is no field supply voltage connected, the output status indicator will display the configured LED mode, the corresponding output state will be reported and the line fault status for that channel will be set to ‘1’. All other output channels will be unaffected, except in the case of common cause wiring and supply voltage faults in the field. The field output voltage and current variables can be monitored to determine the actual operating conditions of each output channel. This additional information assists the user in determining the specific type of wiring fault. Once the specific field wiring fault has been identified and corrected, the output status variables and output status indicator will display the normal on/off status of the field device. 5.3. Module Faults Extensive diagnostics provide the automatic detection of Module faults. The TMR architecture of the Output Module and the diagnostics performed verify the validity of all critical circuits. Using the TMR architecture provides a Fault Tolerant method to withstand the first fault occurrence on the Module and continue normal output controls without interruption in the system or process. Faults are reported to the user through the Healthy status indicators on the Front Panel of the Module and through the INFO and HKEEPING variables. Under normal operations all three Healthy Indicators are green. When a fault occurs, one of the Healthy Indicators will be flashing red. It is recommended that this condition is investigated and if the fault is within the Module, it should be replaced. Module replacement activities depend on the type of spare Module configuration chosen when the system was configured and installed. The Module may be configured with a Dedicated Standby Slot or with a SmartSlot for a spare replacement Module. 5. Fault Finding and Maintenance Trusted TMR 24Vdc Digital Output Module – 40 Channel 30 Issue 14 Rockwell Automation Publication ICSTT-RM280N-EN-P 5.4. Companion Slot For a Companion Slot configuration, two adjacent slots in a Trusted Chassis are configured for the same Output Module function. One slot is the primary slot and the other a unique secondary (or spare) slot. The two slots are joined at the rear of the Trusted Chassis with a double-wide I/O Interface Cable that connects both slots to common field wiring terminations. During normal operations, the primary slot contains the Active Module as indicated by the Active indicator on the Front Panel of the Module. The secondary slot is available for a spare Module that will normally be the Standby Module as indicated by the Standby indicator on the Front Panel of the Module. Depending on the installation, a hot-spare Module may already be installed, or a Module blank will be installed in the Standby slot. If a hot-spare Module is already installed, transfer to the Standby Module occurs automatically when a Module fault is detected in the Active Module. If a hot-spare is not installed, the system continues operating from the Active Module until a spare Module is installed. 5.5. SmartSlot For a SmartSlot configuration, the secondary slot is not unique to each primary slot. Instead, a single secondary slot is shared among many primary slots. This technique provides the highest density of Modules to be fitted in a given physical space. At the rear of the Trusted Chassis, a single-wide I/O Cable connects the secondary slot directly to the I/O Cable connected to the failed primary Module. With a spare Module
