4. Application
There is no automated tool for application conversion from Regent to Trusted, and the applications are
very different. However, it is possible to copy the functionality with the resulting programs looking
similar to the original programs. Use the following steps to ease the process.
In this section, ‘Winterpret’ is used as the name of the Regent application tool. Its predecessor was
PDS, which is still in use on the older Regent systems. The presentation is different but the core
functionality is similar.
A copy of Winterpret (or PDS) will be necessary to read the Regent configuration. This does not need
to be the same issue as used before, but must be loaded with the same extra packages.
4.1. System Configuration
The System.INI file for a Trusted-Regent hybrid is very simple. Insert a T8160 TMR Interface into the
chassis, and insert another T8160 in its companion slot to the right. This allows the system to black-
start with the T8160 in either slot. By convention, slots 1 and 2 are used.
Insert T8151 communications interfaces into the chassis. By convention, slots 7 and 8 are used.
This leaves four slots spare for Trusted I/O modules and interfaces to future Trusted expansion I/O
chassis, which will have a much smaller panel space than the corresponding Regent I/O equivalent.
Configure the communications interface parameters. Replicate the serial port settings from Regent
(baud rate, bits and parity). For Modbus slaves, enable slaves on the ports as appropriate. For Modbus
Master, create a Modbus Master and define its slaves and messages as in the Regent application. For
further information, refer to product description PD-T8151B.
4.2. Toolset I/O Connection Table
The first step is to build the I/O connection table. Add definitions for modules in the Trusted chassis
first.
ttmrp Trusted processor Only one definition required
ttmri_ii TMR Interface One ttmri_ii definition covers both module positions
There is no need to add definitions for the communications interfaces. If the TMR Interface was not
placed in the left-hand slot of the eight narrow slots in the Trusted processor chassis, correct the Slot
number on each of the two boards of the ttmri_ii definition.
Now add the definitions for each Regent I/O module. It is recommended to place these definitions in
the order that they appear in the chassis and slots, but the only real constraint is that 7491 multiplexer
modules must be defined before their multiplexer I/O. Product description PD-T8160 describes each
definition. These definitions each provide connection boards for variables used in the application.
Each definition for a Regent module must be set up with the following parameters:
TICS_CHASSIS and _SLOT The chassis number (1) and the slot number (usually 1) of the
T8160 TMR Interface. (It helps here if the T8160 is in the default position, chassis 1 slot 1).
REGENT_CHASSIS and _SLOT The position of the Regent module; the first I/O chassis is
chassis 1.
There will be further parameters for the second and third module position in definitions applying to
multiple module sets.
Copy these parameters to the entry points on each board.
