Safety Manager Module
The Model 4409 Safety Manager
Module (SMM) acts as an interface
between a Tricon controller and a
Honeywell Universal Control Network
(UCN), one of three principal networks
of the TDC-3000 Distributed Control
System. Appearing to the Honeywell
system as a safety node on the UCN, the
SMM communicates process informa
tion at full network data rates for use
anywhere on the TDC-3000. The SMM
transmits Tricon aliased data (including
system variables) and diagnostic infor
mation to operator workstations in
display formats that are familiar to
Honeywell operators.
The SMM makes the following func
tions available to the TDC-3000:
? Handles critical I/O points and
passes results to the DCS
? Processes Tricon alarms and
propagates them to user-defined
DCS destinations (consoles,
printers, etc.)
? Reads/writes aliased data to satisfy
DCS requests
? Reads Tricon diagnostics for display
by the DCS
? Write protection to lock out changes
to the Tricon controller from all
TDC-3000 sources
?
Time synchronization from the DCS
master clock
?
Peer-to-Peer communication for
plants with many Tricon controllers,
each containing an SMM—the DCS
can use shared data to alert
downstream Tricons of significant
process changes
?
Sequence of Events—transmits
Tricon event data to Universal
Stations for display or History
Modules for recording, to help
determine the cause of plant trips
and increase process up-time
? Hot-spare capability for
uninterrupted communication with
Honeywell networks
