Overview
The Triconex 4409 Safety Manager Module (SMM) provides an interface between a Tricon safety instrumented system and the Honeywell Universal Control Network (UCN) used by the TDC-3000 Distributed Control System. It transfers Tricon process data, alarms and diagnostic information to Honeywell operator stations. Furthermore, it supports peer-to-peer communication, time synchronization and hot-spare operation.
Communication and Network Functions
The 4409 connects the Tricon controller to the Honeywell UCN through two isolated, AC-coupled UCN ports. With a data rate of 5 MBytes per second, the module communicates process information at the full network data rate.
The SMM presents the Tricon controller as a safety node on the UCN. It also transmits aliased process data, system variables and diagnostic information in display formats familiar to Honeywell operators.
Its communication functions include:
- Process data exchange: Reads and writes aliased Tricon data in response to DCS requests.
- Alarm handling: Processes Tricon controller alarms and forwards them to configured DCS destinations, including operator consoles and printers.
- Diagnostic reporting: Reads controller diagnostic information for display through the DCS.
- Sequence of Events: Transfers Tricon event data to Universal Stations for display or History Modules for recording.
- Time synchronization: Receives time synchronization from the DCS master clock.
- Peer-to-peer communication: Shares process data between Tricon controllers equipped with SMM modules, allowing downstream controllers to respond to significant process changes.
Safety and Communication Protection
The 4409 provides write protection to prevent TDC-3000 sources from changing the Tricon controller. This function helps maintain the configured controller settings while allowing the DCS to access process data and diagnostic information.
In addition, the module supports hot-spare capability for continued communication with Honeywell networks. Its status indicators provide information about module operation, UCN activity, transmission and spare readiness.
