Internal System Interface Module Triconex EM 2291

The EcoStruxure Triconex Safety Intelligent Enclosure (SIE) provides

an integrated solution designed to be mounted close to field instrumentation to reduce cabling

The SIE includes Tricon™ CX Universal Input/Output (UIO) modules, power supplies,

and External Termination Panels (ETPs) that are pre-installed and tested,

and can be connected to a wide range of field devices.

The factory-manufactured SIE supports Schneider Electric’s Flexible Lean Execution strategy,

which shortens project schedules and reduces the risk of startup delays.

The Safety Intelligent Enclosure (SIE) consists of a

wall-mounted stainless steel cabinet, Tricon CX I/O

Expansion Chassis, Universal Input/Output (UIO)

modules, power supplies, fans, and termination panels.

Each TCM supports an aggregated data rate of 460.8 Kb/s for all four serial ports.

Tricon programs use variable names as identifiers, while Modbus devices use numeric

addresses called aliases.

Therefore, each Tricon variable name must be assigned an alias that will be read by

or written to the Modbus device.

An alias is a five-digit number that represents the Modbus message type and the address

of the variable in the Ticon. An alias number is assigned in the TriStation.

Any standard Modbus device can communicate with Tricon via TCM, provided an alias is

assigned to the Tricon variable.

The alias number must also be used when the host accesses the Tricon through other

communication modules.

Each TCM contains two network ports - NET 1 and NET 2. Models 4351A and 4353 have

two copper Ethernet (802.3) ports and Models 4352A and 4354 have two fiber optic Ethernet ports.

NET 1 and NET 2 support TCP/IP, Modbus TCP/IP Slave/Master, TSAA, TriStation,

The NET 1 also supports the Peer-to-Peer and Peer-to-Peer Time Synchronization protocols.

A single Tricon system supports up to four TCMs, which must reside in two logical slots.

Different TCM models cannot be mixed in a logical slot.

Each Tricon system supports a total of 32 Modbus masters or slaves, including network and serial ports.

The hot standby feature does not apply to TCMs, but you can replace a defective

TCM while the controller is online.
