FAQ & Expert Procurement Guide

What is the advantage of using the Fiber Optic port on the 3411 over the RJ45 ports?

The fiber interface provides complete electrical isolation and is immune to EMI, making it superior for long-distance runs.

Does the 3411 TCM support simultaneous Modbus and Ethernet/IP traffic?

Yes, the module handles multiple industrial protocols concurrently on the same physical network infrastructure.

How do I address a persistent "Fault" LED on the module faceplate?

Check the TriStation diagnostic buffer; this often points to a configuration mismatch or peer-to-peer heartbeat failure.

Is this module hot-swappable in a running Tricon system?

Yes, the 3411 supports hot-swapping in chassis with designated spare slots or redundant configurations.

Selection Guidance: Can I replace an older 4351B module with this 3411?

The 3411 is a modern TCM; verify your Triconex system version and firmware compatibility before upgrading.
