The Model 4409 Safety Manager module (SMM) serves as an interface between the Tricon Controller and the Honeywell Universal Control Network (UCN), one of the three major networks TDC-3000 distributed control systems. Appears on Honeywell systems as secure node SMMS on UCNs to transfer process information at full network data rates for use anywhere on TDC-3000. Multiple myeloma transmits Tricon alias data (including system variables) and diagnostic information to operator workstations in a familiar display format for Honeywell carriers.
The TDC-3000 provides the following functions through the SMM:
• Handle critical I/O points and pass results to DCS
• Handle Tricon alerts and propagate them to user-defined DCS destinations (console, printer, etc.)
• Reads/writes alias data to satisfy DCS requests
• Read Tricon diagnostic display is controlled by DCS
• Write protect, lock changes to the Tricon Controller tdc-3000 source
• Synchronize the master clock from the DCS
• Point-to-point communication has a number of Tricon controllers for plants, each containing a smm-DCS that can use shared data to alert downstream Tricons of significant process changes
• Event Sequence – Transmits Tricon event data to a common display or history station module recording to help determine the cause of plant trips and increase the uptime of the process
• Hot spare capability uninterrupted with Honeywell network
