Provides configured external communications for the Tricon controller architecture.
Product Identification
TCM4355X identifies a Triconex Tricon Communication Module used in the communication architecture of a Tricon safety controller. The module is configuration-sensitive and must be matched to the approved controller release and TriStation project.
Independent ISASecure certification records identify TCM 4355X within a certified Tricon communication-module scope. Schneider Electric documentation for exact technical details is access-controlled, so unsupported port counts or protocol claims are intentionally omitted.

Functions
Exchanges data only through the protocols and ports enabled in the approved project and firmware.
Reports module and link diagnostics to the Tricon maintenance environment.
Supports lifecycle maintenance when hardware and firmware baselines remain controlled.
Applications
- Safety instrumented systems where the approved Tricon architecture specifies TCM4355X.
- Communication replacement during a planned maintenance window with configuration and firmware evidence available.
- Controller-network upgrades that retain validated safety boundaries and cybersecurity controls.
- Spare verification requiring the exact TCM4355X label rather than a generic TCM description.
Lifecycle
- Export or print the TriStation hardware and communication configuration before removal.
- Record module firmware, chassis position, cable destinations, network addresses and partner systems.
- Follow Schneider Electric procedures for online replacement only when the controller state and project permit it.
- After installation, verify diagnostics, every configured link, data quality, time behavior and the safety-system management-of-change record.

FAQ
What information is required to quote TCM4355X?
Provide the complete module label, Tricon system release, TriStation version, firmware, chassis position and configured network interfaces.
Can another Tricon TCM replace TCM4355X?
Not from the shared family name alone; hardware support, firmware, project configuration and certified system scope must be checked.
Why are generic protocol lists omitted for TCM4355X?
The exact enabled interfaces depend on controlled Schneider Electric documentation and project configuration; guessing them could create an unsafe integration decision.
How should communications be tested after fitting TCM4355X?
Test every configured peer, data direction, update behavior, diagnostics and failure response under the approved site validation plan.
What cybersecurity evidence should accompany TCM4355X maintenance?
Retain firmware provenance, approved network diagram, access settings, change authorization and results from the post-maintenance communication test.
