Description
ICS Triplex 5600633 T8800 Trusted TMR Processor
The ICS Triplex 5600633 (often referred to as the T8800) is a high-integrity controller designed for use within the Trusted Triple Modular Redundant (TMR) system. This TMR Processor is the core intelligence unit of the Trusted platform, specifically engineered for safety-critical applications such as Emergency Shutdown (ESD), Fire and Gas (F&G) detection, and Burner Management Systems (BMS).
Product Introduction
The T8800 (5600633) utilizes a Fault-Tolerant architecture that provides virtually 100% availability for critical control loops. It achieves this through a 2-out-of-3 (2oo3) voting mechanism performed across three independent processing channels. This ensures that even if a hardware failure occurs in one channel, the system continues to operate safely and correctly without interruption. The module is widely used in global oil, gas, and power generation industries to meet SIL 3 (Safety Integrity Level 3) requirements.

Usage Instructions
- Installation: The T8800 module must be inserted into the dedicated controller slots of the Trusted Controller Chassis. Ensure the module is fully seated and the locking levers are engaged.
- Redundancy Setup: For maximum availability, ensure the system is configured as a Triple Modular Redundant unit. The chassis logic will automatically handle the synchronization between the three internal processing slices.
- Programming: Use the TOOLSET software environment (IEC 61131-3 compliant) to develop safety logic. Configuration is typically performed via the redundant Ethernet ports.
- Diagnostics: Monitor the front-panel LED indicators. A “Healthy” status requires all three channel LEDs to be green. Any red LED indicates a fault in a specific slice that requires maintenance.
- Hot-Swapping: The T8800 supports “Hot-Replacement.” In a running system, a faulty processor module can be replaced with a new one; the system will automatically re-educate the new module and return to full TMR status.
Product Q&A
- Q: What is the difference between the 5600633 and newer T8110B processors?
- A: The 5600633 (T8800) is a legacy Trusted processor. While the T8110B is the modern standard, the 5600633 remains essential for maintaining older Trusted installations without requiring a full system redesign.
- Q: Does the module require a separate battery for memory backup?
- A: The Trusted system typically utilizes non-volatile Flash memory for the application program, reducing the reliance on batteries for long-term storage of safety logic.
- Q: How does the “Voting” work?
- A: All three processors execute the same code simultaneously. Their results are compared at the I/O bus level. If one processor disagrees with the other two, it is over-ridden by the majority (2-out-of-3).
