Triconex 3105 Tricon v9/v10 Communication Module
The Triconex 3105, also cataloged as the 3105 Communication Module, operates as a dedicated hardware component for deterministic data exchange and protocol translation within Tricon v9 and v10 control chassis platforms. The module bridges internal chassis communication paths with external HMIs, DCS platforms, and field networks across dual Ethernet and serial channels.

Triple Modular Redundancy (TMR) 2oo3 Architecture Integration
The module operates within the Triple Modular Redundancy (TMR) framework to maintain fault-tolerant communication without degrading safety loop performance. Triplicated internal processing channels interface with the 2oo3 voting architecture of the main processors to validate incoming network commands before execution. Galvanic isolation across all communication ports protects internal processing nodes from ground potential shifts and external field transients. In the event of a channel line fault, internal diagnostic logic activates fail-safe state execution, seamlessly switching active data throughput to redundant serial or Ethernet paths without interrupting chassis background logic.
Frequently Asked Questions
Q: Does the Triconex 3105 support hot-swapping within an active Tricon chassis?
A: Yes, the module can be removed and replaced under active chassis backplane power without tripping the safety system or disrupting CPU logic execution.
Q: How does the module handle simultaneous Ethernet and serial protocol transactions?
A: The onboard dual processor channels process Modbus TCP/IP and Modbus RTU protocols concurrently on separate execution threads, maintaining deterministic scan times across all active ports.
Q: Is an external power supply required to operate field communication interfaces?
A: No, all internal processing circuits and isolated communication port drivers draw operating power directly from the Tricon chassis backplane bus, consuming less than 10 W.
Field Installation Guidelines
Ensure main chassis power is stable and ESD grounding wrist straps are connected prior to handling the module. Align the card edge guides with the targeted slot in the Tricon chassis and slide the assembly inward until the backplane connectors seat completely. Tighten the top and bottom retaining screws to secure the chassis connection and ground grounding tabs.
Route serial and Ethernet communication cables in dedicated low-voltage instrument trays, maintaining a minimum physical separation distance of 200 mm from high-voltage AC conductors and motor power cables. Connect cable drain shields to a single point low-impedance safety earth ground at the cabinet entry gland. Verify that operating ambient temperatures around the rack remain between 0 deg C and +60 deg C to prevent thermal buildup.
