Description

TRICONEX 3005

Tricon Communication

Module

The Tricon Communication Module

(TCM),which is compatible with only

Tricon v10.0 and later systems,allows

the Tricon to communicate with TriStation 1131,other Tricon or Trident

controllers,Modbus master and slave

devices,and external hosts over

Ethernet networks.

Each TCM contains four serial ports,

two network ports,and one debug port

(for Triconex use).

Each serial port is uniquely addressed

and can be configured as a Modbus

master or slave.Serial Port#1 supports

either the Modbus or the Trimble GPS

interface.Serial Port#4 supports either

the Modbus or the TriStation interface.

Each TCM supports an aggregate data

rate of 460.8 kilobits per second,for all

four serial ports.

Any standard Modbus device can

communicate with the Tricon through

the TCM,provided that aliases are

assigned to the Tricon variables.Alias

numbers must also be used when hostNe

Description

Main Processor Modules

Model 3005 Main Processors(MP)are

available for Tricon v9.6 and later

systems.For detailed specifications,

see the Planning and Installation Guide

for Tricon Systems.

Three MPs must be installed in the

Main Chassis of every Tricon system.

Each MP independently communicates

with its I/O subsystem and executes the

user-written control program..

Sequence of Events(SOE)

and Time Synchronization

During each scan,the MPs inspect

designated discrete variables for state

changes known as events.When an

event occurs,the MPs save the current

variable state and time stamp in the

buffer of an SOE block.

If multiple Tricon systems are

connected by means of NCMs,the time

synchronization capability ensures a

consistent time base for effective SOE

time-stamping.See page 72 for more

information.

Diagnostics

Extensive diagnostics validate the

health of each MP,I/O module and

communication channel.Transient

faults are recorded and masked by the

hardware majority-voting circuit.

Persistent faults are diagnosed and the

errant module is hot-replaced.

MP diagnostics perform these tasks:

●Verify fixed-program memory and

static RAM

●Test all basic processor and floatingpoint instructions and operating

modes

●Validate user memory by means of

the TriBus hardware-voting

circuitry

●Verify the shared memory interface

with each I/O communication

processor and channel

●Verify handshake and interrupt

signals between the CPU,each I/O

communication processor and

channel

●Check each I/O communication

processor and channel

microprocessor,ROM,shared

memory access and oopback of RS485 transceivers

●Verify the TriClock and TriBus

interfaces
