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 and the simulation enable has been set within the module’s
configuration in the system.ini file.
3.3. Sequence of Events Configuration
Each Boolean Input Variable can be configured for automatic Sequence of Events (SOE) logging. This
applies to the Input 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 the
box for Sequence of Events to enable the variable for automatic SOE logging.
During operation, the input module automatically reports time-stamped change of state information for
the input 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 input 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 4-20 mA Isolated Analogue Input Module T8433 are contained in PD-8082B.
Certain characteristics apply to the entire module and are considered Module Configurable Items.
Other characteristics apply to individual input 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.
