3. Application

3.1. Module Configuration

There is no configuration required to the physical output 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 output

module after applications are downloaded and during Active/Standby changeover.

The

IEC1131 TOOLSET provides the main interface to configure the output module. Details of the

configuration tools and configuration sequence is provided in PD-8082B. There are three procedures

necessary to configure the output module. These are:

1. Define the necessary I/O variables for the field output 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

System Configuration Manager, define custom LED indicator modes,

per-channel shutdown states, and other module settings.
