AUI data path
The 15-pin connector carries a 10 Mbps AUI link from the ACM to the DNBI.

Triconex 4609 Advanced Communication Module
Controller data exchange through Nodebus and TS/TSAA links
SECTION 01
Product Description
The Triconex 4609 is an Advanced Communication Module for Tricon v10.x or earlier systems. It links a Tricon controller with a Foxboro I/A system through Nodebus connections and provides a separate TS/TSAA network port for TriStation and TSAA data exchange.
On the Nodebus side, the 4609 provides a BNC connection for RG-58 cable, a 15-pin AUI connection to the DNBI and a 9-pin RS-423 control-bus connection to the DNBI. The two 10 Mbps data connections and the 2400-baud control link serve different parts of the I/A interface rather than one shared connector.
Front-panel status on the 4609 separates module condition from network activity. Pass, Fault and Active report the module, ONLINE and SBRDY report the Nodebus state, and TX/RX indicators show traffic for the individual ports.

SECTION 03
Foxboro I/A Nodebus Interface
The 4609 divides Nodebus data and control connections across dedicated connectors leading to the DNBI and I/A network.
Control-bus path
The 9-pin RS-423 connection carries the 2400-baud Nodebus control relationship with the DNBI.
Coaxial network path
BNC connectors provide the RG-58 network interfaces assigned to Nodebus and TS/TSAA traffic.
SECTION 04
ACM Status and Data Exchange
The 4609 exposes module health, Nodebus readiness and per-port traffic as separate front-panel states.
Module condition
PASS, FAULT and ACTIVE indicate whether the ACM has passed diagnostics and is active in the controller.
Nodebus state
ONLINE shows the Nodebus connection state, while SBRDY reports spare readiness.
Traffic visibility
TX and RX indicators identify transmitted and received data for each monitored communication port.
SECTION 05
Common Questions
What system does Triconex 4609 connect to?
The 4609 interfaces a Tricon controller with a Foxboro I/A system. Its Nodebus connectors lead through the DNBI connection path. The ACM presents the Tricon controller as a safety node on the I/A Series Nodebus rather than as a general Ethernet device.
What is the purpose of the 15-pin connector on Triconex 4609?
It is the AUI cable connection to the DNBI. That data path operates at 10 Mbps. The AUI and control-bus cables therefore connect to different DNBI interfaces and should not be interchanged.
What uses the 9-pin Nodebus connector on Triconex 4609?
The 9-pin RS-423 connector carries the control-bus connection to the DNBI. Its listed communication rate is 2400 baud. Its lower rate and control purpose distinguish it from the 10 Mbps Nodebus data connection.
Does Triconex 4609 provide a separate TS/TSAA port?
Yes. A BNC connector on the module connects the TS/TSAA network using RG-58 50-ohm cable. That BNC path is separate from the DNBI AUI and RS-423 connections used by the Nodebus interface.
How are Triconex 4609 network and module states distinguished?
PASS, FAULT and ACTIVE describe module condition. ONLINE, SBRDY, TX and RX expose Nodebus readiness and port activity. Reading the indicator groups separately helps distinguish a module fault from an inactive or disconnected network path.
Which Tricon versions support Triconex 4609?
The module is listed for Tricon v10.x or earlier systems. This version boundary should be checked before selecting the communication hardware. The controller system version and the existing communication-module combination should both be reviewed before installation.
