T8110B ICS Trusted TMR Processor

T8110B 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.

• 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.

 

There are eleven status LEDs on the Processor Front Panel; three Healthy, one Active, one Standby, one Educated, one Run, one Inhibit, one System Healthy, and two User. The Healthy indicators are controlled directly by each module slice. All LEDs are controlled by the FPU. The FPU receives data from each of the module slices. The Front Panel Unit (FPU) performs a 2oo3 vote on each data bit from the slices and sets the indicators accordingly.

 

 

1.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.

2.Complex I/O Equipment Definition：All Trusted Systems require a Processor definition in the I/O Connection Table. 

3.Inter-Module Bus：Each Processor FCR contains a Bus Interface to the Inter-Module Bus. The triplicated Inter-Module Bus provides communication interconnection between modules in the Trusted Controller Chassis, at a data transfer rate of up to 150 Mbaud.

4.Isolation：All signals exchanged between FCRs are protected to prevent the propagation of faults between independently powered FCRs. The Front Panel diagnostics port is electrically isolated from the Front Panel FCR. The Processor and Front Panel FCR provide electrical isolation for the 24 Vdc power feed in addition to the POWER WARNING signal.

Before installation, visually inspect the module for damage. Ensure that the module housing appears undamaged and inspect the I/O connector at the back of the module for bent pins. If the module appears damaged or any pins are bent, do not install the module. Do not try to straighten bent pins. Return the module for replacement.

Ensure that the module is of the correct type.

Record the module type, revision and serial number before installation.

 

To install the module:

1. Ensure that the field cable assembly is installed and correctly located.

2. Release the ejector tabs on the module using the release key. Ensure that the ejector tabs are fully open.

3. Holding the ejectors, carefully insert the module into the intended slot.

4. As soon as the Front Panel LEDs illuminate, push the module fully home by pressing on the top and bottom of the module fascia. The module should be inserted promptly to ensure that it connects to the Interface Adapter before reading the licenses.

5. Close the module ejectors, ensuring that they click into their locked position.

 

The module should mount into the chassis with a minimum of resistance. If the module does not mount easily, do not force it. Remove the module and check it for bent or damaged pins. If the pins have not been damaged, try reinstalling the module.
