The Trusted TMR processor is the central processing component in a Trusted system. Its triple-modular-redundant architecture is designed to tolerate faults, but spare selection still depends on the exact processor, system release and approved configuration.
EDITORIAL REVIEW · 4 SEPTEMBER 2026
Three processing paths.
One controlled decision.
Understand the voting architecture, then keep procurement evidence, configuration and functional-safety approval connected.
Understand what the Trusted processor does
Rockwell Automation’s product description identifies the Trusted TMR Processor as the main processing component in a Trusted system. It processes I/O data across the Trusted inter-module communications bus and provides system control and monitoring. Browse the Trusted TMR processor system catalogue to organize a parts enquiry, not to define the safety application.
The manufacturer describes a hardware-implemented fault-tolerant architecture and 3-2-0 operation for T8110/T8110B. These are platform characteristics, not proof that a particular processor, configuration or application remains compliant. Always use the applicable safety manual and certificate conditions.
Keep T8110 variants and system context visible
Processor identity
Record T8110, T8110B or other approved variant, full label, hardware revision and installed slot. Do not compress the requirement to “Trusted CPU.”
Application context
Record system release, project configuration, chassis and interfaces, active/standby arrangement and relevant safety documentation.
Manufacturer documents note feature differences between variants; for example, some communications and time-synchronization features are associated with T8110B. That does not mean those features may be used in a safety function without the conditions defined by the manual and certification scope.
Build a controlled spare and recovery plan
A processor spare is useful only when its identity, configuration requirements and acceptance path are understood. Preserve approved application and system records under change control. Record who can assess the replacement, what evidence is needed at receipt and how validation and return to service are authorized.
| Layer | Procurement question | Control point |
|---|---|---|
| Processor | Is the exact approved variant available? | Full identity, revision, condition and inspection evidence. |
| Chassis and interfaces | Does the offered unit belong to this system configuration? | Applicable manuals and approved equipment list. |
| Application | Can the approved project be recovered and validated? | Controlled backup, tool version and responsible personnel. |
| Lifecycle | Is an interim spare or a planned migration more appropriate? | Risk, service information, outage window and project horizon. |
Keep independent supply evidence separate from manufacturer lifecycle support. Use the EOL spare-parts planning guide to compare spare, repair and modernization decisions without inventing a universal support deadline.
Define the commercial evidence before ordering
Full catalogue number and revision.
Declared state and storage history available.
What was checked and what was not.
Quantity, dispatch, destination and terms.
Review Moore Automated’s storage facilities for company context, but require the specific quotation to confirm the actual offered unit. A warehouse image is not evidence that a particular processor is currently available.

Frequently asked questions
What is the Trusted TMR Processor?
It is the main processing component in a Trusted system, providing system control and monitoring and processing I/O data over the inter-module bus.
What does TMR mean here?
Triple modular redundancy uses three processing paths and voting to identify discrepancies and tolerate defined faults.
Are T8110 and T8110B identical?
Do not assume so. Review the exact product description, system release and approved configuration for the installed processor.
Can a processor be replaced without application recovery planning?
No. Keep controlled backups, tool and release information, acceptance criteria and qualified personnel in the recovery plan.
Does SIL 3 wording approve any configuration?
No. Certification applies within defined hardware, software, configuration and application conditions. Review the applicable safety manual and certificate.
What should a sourcing enquiry contain?
Provide the full processor label, system release and arrangement, quantity, condition and evidence requirements, destination and deadline.
Make the Trusted processor enquiry traceable.
Send the exact processor reference, system context and acceptance evidence required. Moore Automated can review commercial sourcing while the site retains safety authority.
