System Requirements & Architecture

Trusted TMR System Requirements

• One T8111 or T8110 Trusted TMR Processor
• One T8311 Trusted Expander Interface Module (for interface between T8100 controller chassis and CS300 expander chassis)
• One T8151B Trusted Communication Interface (Ethernet interface for engineering workstations, other Trusted systems, or third-party equipment; T8151C conformal coated version is also compatible)
• One T8153 Trusted Communications Interface Adapter (for physical connections to the T8151B module)

Additional System Requirements

• The T8100 Trusted Controller Chassis must be installed in a rack with doors and side panels (doors kept closed during normal operation) to ensure EMC compliance of the 8162 Bridge Module.
• The front door may have a window for LED visibility.
• CS300 equipment must be installed inside the cabinet and correctly earthed (see Physical Installation Design for details).

System Architecture Features

• Three 8162 CS300 Bridge Modules enable connection between the Trusted TMR System and legacy CS300 I/O.
• Approved cabling and accessories are required for system communications:
  • Trusted TMR System carries a T8312 Expander Interface Adaptor.
  • CS300 rack carries a TC-324-02 PCB.
  • One TC-322-02 cable assembly (triple, bidirectional communication link) transmits data between the two components.
  • Cable assemblies are available up to 15m; the system supports cables up to 50m in length.
• The migrated system supports the pre-existing configuration of CS300 I/O modules.
• Communications from legacy CS300 systems to workstations, printers, and distributed control systems must be routed through the T8151 Communications Interface module.

Testing Procedure

Test Steps

1. If testing on a live system: Disconnect the final element associated with the channel under test to prevent spurious actions during the proof test. If not testing on a live system, proceed to Step 2.
2. Disconnect the switched output to the final element, while keeping the 120V AC supply connected and energized. Verify that the tested output reports a STATE value of 3 (No Load).
3. Energize the output channel and verify that the channel STATE remains at 3 (No Load). If the energized output reports STATE 4 (Output Energized) or STATE 5 (Field Short Circuit), the output channel likely has a failed varistor, and the FTA (Field Termination Assembly) must be replaced.
4. De-energize the output, reconnect the final element field connection, and verify that the output reports a STATE value of 2 (Output Deenergized).

Installation Guide

Preparation Steps

1. Gather necessary tools: screwdriver, torque wrench, cable cutter, and wire stripper.
2. Inspect the T8311 module for transportation damage (check housing, connectors, and physical integrity).
3. Verify compatibility with the T8300 chassis (exclusive compatibility) and confirm the module model (ICS Triplex T8311) matches application requirements.
4. Prepare the 20-32Vdc power supply and communication cables (approved for industrial use, compatible with 250Mbps data transfer).
5. Ensure the T8300 chassis is powered off and properly grounded before installation.
6. Confirm all associated modules (T8111/T8110, T8151B, T8153) are correctly configured and ready for integration.

Mounting

1. Locate the appropriate slot in the T8300 chassis for the T8311 module.
2. Align the module with the chassis guide rails and slide it into the slot until it clicks into place.
3. Secure the module to the chassis using the provided mounting screws, tightening to the recommended torque to ensure stability.
4. Ensure adequate ventilation around the module (critical for heat dissipation, as the module dissipates 40W) — maintain a minimum 8cm clearance from other components.

Wiring

1. Power Supply Wiring: Connect the 20-32Vdc power supply to the module’s dedicated power terminals, ensuring correct polarity to avoid damage.
2. Expander Bus Wiring: Connect the module to the expander chassis backplane and Trusted controller chassis (T8100) via the expander bus, following the system wiring diagram.
3. Legacy I/O Wiring: If integrating with CS300 I/O, connect the T8312 Expander Interface Adaptor to the T8311, and the TC-324-02 PCB to the CS300 rack, using the TC-322-02 cable assembly (ensure cable length does not exceed 50m).
4. Shielding: Use shielded cables for all communication and power wiring, connecting the cable shield to the module’s ground terminal to prevent electromagnetic interference and ensure EMC compliance.

Testing & Configuration

1. Power on the T8300 chassis, T8311 module, and associated Trusted components (controller, communication modules).
2. Verify the module’s power status and LED indicators (green = healthy, no fault lights).
3. Perform the communication path integrity test outlined in the “Testing Procedure” section to ensure the bit error rate is within acceptable limits.
4. Verify integration with legacy CS300 I/O modules (if applicable) by checking data transmission between the controller chassis and CS300 expander chassis.
5. Confirm the expander bus data rate (250Mbps) and module clock (50MHz) are operating correctly via the system diagnostics interface.

Usage Notes

• The T8311 is exclusively compatible with the T8300 chassis — do not attempt to install it in other chassis models.
• Ensure adequate ventilation to manage 40W heat dissipation; insufficient cooling may cause overheating and module failure.
• Do not exceed the 20-32Vdc voltage range or 40W maximum load, as this may damage the module.
• Use only approved cabling and accessories (e.g., TC-322-02 cable assembly) for system communications to maintain performance and safety.
• Follow the recommended testing procedure regularly (per IEC61511) to verify communication path integrity and prevent dangerous residual errors or spurious trips.
• The T8311 must be installed in a properly earthed cabinet with closed doors (during normal operation) to ensure EMC compliance.
• When replacing the module, ensure the new module has the same model and certifications to maintain system compatibility and safety integrity.
