The FCR Status channel reports the fault status of the active and standby modules. The value is bit-
packed as shown below, the least significant byte is used with the most significant 8-bits set to zero:

The ‘Primary Module is active’ channel is set to non-zero if the primary module is the current active
module, i.e. the active module is in the chassis and slot numbers defined within the OEM parameters.
The ‘Active Module is simulated’ channel is set to non-zero if the active module is being simulated, this
will only be set if the module is not present or the simulation enable has been set within the module’s
configuration in the system.ini file.
3.3. Sequence of Events Configuration
Each Boolean Output Variable can be configured for automatic Sequence of Events (SOE) logging.
This applies to the Output Status and Line Fault Status variables. A Boolean variable is configured for
SOE during the variable definition in the Data Dictionary Editor. To select SOE, press the Extended
Button in the Boolean Variable Definition Dialog Box to open the Extended Definition Dialog. Then
check to box for Sequence of Events to enable the variable for automatic SOE logging.
During operation, the output module automatically reports time-stamped change of state information
for the output data. The TMR Processor automatically logs change of state for configured SOE
variables into the system SOE Log. The SOE Log can be monitored and retrieved using the SOE and
Process Historian Package running on the EWS. This software package is described in PD-8013.
3.4. SYSTEM.INI File Configuration
There are many operating characteristics of the output module that can be customised for a particular
application. The System Configuration Manager is a tool that allows the user to configure the specific
operating characteristics for each module. Descriptions of the items that may be configured for the
Trusted
TM 24/48V dc Digital Output Module T8461 are contained in PD-8082B.
Certain characteristics apply to the entire module and are considered Module Configurable Items.
Other characteristics apply to individual output channels and are considered Channel Configurable
Items. There are specific default settings for each of the configurable items. If the default settings are
appropriate for a given application, then customization of the module definition in the System
Configuration Manager is not required.
In order for De-energising short circuit detection to function a template is required. The template will
allow individual channels to be set to either detect or not a short circuit (less than a nominal 30 ohms
for Level 1 hardware builds or a nominal 17 ohms for level 2 builds).
