ICS TRIPLEX T8110B Trusted TMR Processor

The Trusted® Processor is the main processing component in a Trusted System. It is a powerful,

user-configurable module providing overall system control and monitoring facilities and processes

input and output data received from a variety of analogue and digital Input / Output (I/O) modules

across a Trusted TMR Inter-Module Communications Bus.

The range of applications for the Trusted TMR Processor vary in integrity level and include fire and

gas control, emergency shutdown, monitoring and control, and turbine control.

Features:

• Triple Modular Redundant (TMR), fault tolerant (3-2-0) operation.

• Hardware Implemented Fault Tolerant (HIFT) architecture.

• Dedicated hardware and software test regimes which provide very fast fault recognition and

response times.

• Automatic fault handling without nuisance alarming.

• Time-stamped fault historian.

• Hot replacement (no need to re-load programs).

• Full suite of IEC 61131-3 programming languages.

• Front panel indicators that show module health and status.

• Front panel RS232 serial diagnostics port for system monitoring, configuration and

programming.

• IRIG-B002 and 122 time synchronisation signals (available on T8110B only).

• Active and Standby processor fault and failure contacts.

• Two RS422 / 485 configurable 2 or 4 wire connections (available on T8110B only).

• One RS485 2 wire connection (available on T8110B only).

• TϋV Certified IEC 61508 SIL 3.

Application

Module Configuration

The Trusted TMR Processor requires no hardware configuration.

Every Trusted System requires a System.INI configuration file. Details of how to design this

are given in PD-T8082 (Trusted Toolset Suite). The configuration has a Processor assigned to

the left slot of the Processor chassis by default. The System Configurator allows the

selection of options on ports, IRIG and system functions. The use of the System Configurator

is described in PD-T8082. The options are described below.
