T8110 Processor Module Trusted TMR | ICS Triplex

Configured for high-integrity logic execution in Trusted TMR systems, the ICS Triplex T8110 (T8110 Processor Module) provides direct physical and electrical execution. The module serves as the primary controller for TMR chassis architectures, managing application execution, I/O scan cycles, and inter-module bus communication within deterministic safety loops.

Hardware Specifications

SIS Triple Modular Redundancy (TMR) Architecture

The T8110 utilizes a triple modular redundancy (TMR) 2oo3 architecture to ensure continuous fail-safe state execution. Through this redundant framework, the module performs real-time voting on inputs and cross-checks processor states to identify and isolate faults without interrupting the control process. Galvanic isolation is implemented across the triple-redundant Inter-Module Bus to prevent electrical noise from propagating between chassis slots, ensuring that the integrity of the safety logic is maintained even in the presence of localized hardware failures.

Frequently Asked Questions

Q: Can the T8110 be hot-swapped while the system is under power?

A: The T8110 is designed for hot-swap capability within the T8100 chassis. It is required to place the processor node in a maintenance mode via the engineering workstation prior to physical removal to ensure the TMR system correctly handles the temporary loss of the processing channel.

Q: What are the requirements for memory integrity verification?

A: The T8110 employs ECC-protected DRAM and checksum-validated EPROM to ensure logic and data integrity. Upon power-up or system reset, the module performs an internal diagnostic check on its FLASH and NVRAM segments; discrepancies in these memory areas will prevent the processor from entering a run state.

Field Installation Guidelines

1. Verify that the T8100 chassis backplane power is stable and within the 20 VDC to 32 VDC range before installation.
2. Align the T8110 module carefully with the chassis guide rails to avoid damaging the high-density backplane connectors.
3. Once seated, ensure the front-panel captive screws are tightened to establish a robust ground connection to the chassis frame.
4. Confirm that the Inter-Module Bus termination is correctly installed at the end of the bus chain to prevent signal reflections and data communication errors.
5. After physical installation, perform a status check via the configuration software to ensure the processor has synchronized with the redundant TMR counterparts and is reporting a healthy status.
