3. Application
3.1. Module Configuration
There is no configuration required to the physical input module. All configurable characteristics of the
module are performed using tools on the EWS and become part of the application or system.ini file
that is loaded into the TMR Processor. The TMR Processor automatically configures the input module
after applications are downloaded and during Active/Standby changeover.
The IEC1131 TOOLSET provides the main interface to configure the input module. Details of the
configuration tools and configuration sequence are provided in PD-8082B Trusted
TM Toolset Suite.
There are three procedures necessary to configure the input module. These are:
1. Define the necessary I/O variables for the field input data and module status data using the
Dictionary Editor of the IEC1131 TOOLSET.
2. Create an I/O module definition in the I/O Connection Editor for each I/O module. The I/O
module definition defines physical information, e.g. Chassis and Slot location, and allows
variables to be connected to the I/O channels of the module.
3. Using the Trusted TM System Configuration Manager, define custom LED indicator modes,
per-channel threshold levels and noise filtering, and other module settings.
3.2. T8433 Complex Equipment Definition

Table 3 Complex Equipment Definition
There are two OEM parameters included in the first rack (THRSHIN Board). These OEM parameters
define the primary module position; declaring the module’s chassis and slot location. There is no need
to define the secondary module position within the IEC1131 TOOLSET. Where systems may be
required to start-up with a module in the secondary position as the active module, e.g. primary module
is not installed when application is started, the secondary module’s position should be declared in the
module definition of the System Configuration Manager.
