Overview Manuals Applications Connectivity Firmware & Updates Compatibility

Features:

  • Adds copper Ethernet and serial communication paths to a Tricon controller.
  • Separates plant-network services from the safety execution channels.
  • Provides onboard status and communication diagnostics for maintenance.
The product is the original 4351 TCM generation and must be identified independently from the A and B revisions.

It carries selected control data to external hosts while maintaining the Tricon fault-tolerant controller architecture.

System release, COM-slot rules, IP addressing, serial configuration and firmware generation must all match the existing project.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Connects supervisory hosts and engineering workstations to a Tricon system over copper media.
  • Exposes approved controller data to plant information and maintenance networks.
  • Replaces an installed first-generation 4351 without introducing a later incompatible TCM family.
  • Copper Ethernet interfaces provide the plant-network connection for this TCM generation.
  • Serial communication remains available for supported host and maintenance functions.
  • Cable media, port assignment and network segmentation must follow the original cabinet design.
  • TCM capability depends on firmware that is compatible with the controller system release.
  • A replacement should be checked for approved firmware before the project configuration is restored.
  • Updates must follow the Tricon maintenance procedure and preserve the validated network settings.
  • Model 4351 belongs to an earlier TCM generation than 4351A, 4351B, 4352A and 4352B.
  • Mixed installation of those generations in one Tricon system is specifically prohibited.
  • The communication slot and connected chassis must satisfy the documented Tricon layout rules.
Description
Triconex 4351 is a copper-media Tricon Communication Module from the earlier TCM hardware family. It combines Ethernet services with serial controller connectivity for plant hosts and engineering access. The original 4351 generation combines copper Ethernet and serial connectivity in the Tricon communication position for controller-to-host data exchange.

The module transfers selected controller data without disturbing the triplicated safety execution path. TCM firmware and system software establish the supported protocols, address behavior and diagnostic functions. Its IEEE 802.3 network path and system communication bus let supervisory applications reach controller data without assigning the module a field-I/O role.

Do not mix 4351/4352 hardware with later 4351A, 4351B, 4352A or 4352B modules in one Tricon system. Confirm release compatibility, copper network interfaces, COM-slot placement and downloaded configuration before exchange. Release compatibility determines whether the original TCM hardware is valid, and chassis-two installations may require the documented 9001 I/O-COMM cable path.

Technical notes
4351 cannot coexist with later 4351A/B or 4352A/B TCM generations in the same system; verify controller release before installation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which model-specific capability belongs to 4351?
The exact 4351 model and its original copper TCM generation distinguish it from 4351A and 4351B successors.
How should 4351 be paired with the surrounding system hardware?
Check the Tricon software release, COM-slot population, I/O-COMM cabling and Ethernet network design.
Where is 4351 normally deployed in an industrial installation?
It provides approved plant-host and engineering connectivity while the main processors execute safety logic.
How does Apter Power confirm sourcing for 4351?
Apter Power can confirm labeling, revision, firmware condition and current lead time against the project requirement.
What commissioning record should be reviewed during a 4351 swap?
Record IP addressing, port settings and firmware, then ensure no incompatible later-generation TCM remains in the system.
Which ordering inputs help prepare a firm 4351 quotation?
Supply the module revision, controller version, chassis position, required interfaces, quantity and shipping destination.
