4409 SMM TRICONEX Safety Manager Module

The Model 4409 Safety Manager Module (SMM) functions as an interface between a Tricon safety controller (part of a Triconex SIS) and the Honeywell

Universal Control Network (UCN), which is a principal network used in Honeywell’s TDC-3000 Distributed Control Systems.

Q1: What are the performance capabilities of the UCN interface?

The SMM operates at the full data rate of the Universal Control Network, typically around

5 MBytes/sec over the dual isolated ports.

Q2: What version(s) of Tricon or Honeywell systems are supported?

The SMM is referenced in Tricon technical product guides for several versions (for example, Tricon version 9.4) and

 is specifically designed to interface with the Honeywell Universal Control Network (UCN)

of TDC-3000 DCS environments.

Q3: What happens if the SMM fails or loses connection?

If an SMM fails or loses communications, the hot-spare capability allows a standby SMM to take over communication

 functions with minimal or no interruption to the Honeywell network. Redundant UCN ports also

 help mitigate single-point communication path failures.

Q4: Does the Honeywell system have write access to the Tricon controller?

The SMM supports write protection. This feature can lock out write or configuration changes to the Tricon

 controller from any TDC-3000(Honeywell) sources, ensuring that safety logic remains

 secure and under the exclusive control of the Tricon side.
