Triconex 3624 Digital Output Module

HIM (Hiway Interface Module, Model 4509): connects Tricon with Honeywell TDC 3000 (via Hiway gateway and LCN) or TDC 2000 (via Data Hiway), supporting communication between high-level devices on LCN/Data Hiway and Tricon; 2 isolated Data Hiway channels, baud rate of 250 kbps, equivalent to 4 extended Data Hiway port addresses, providing 8 Hiway addresses, data refresh<0.5 seconds; Support hot standby, power load<10 watts, isolated 500 VDC, with multiple status indicator lights.

ACM (Advanced Communication Module, Model 4609): connects Tricon with Foxboro I/A Series system as a secure node on Nodebus, transmitting process information at full network rate, and transferring Tricon alias data and diagnostic information to the operation station in a format familiar to Foxboro operators; Support critical I/O point processing, alarm processing and propagation, alias data read and write, Tricon diagnostic read, write protection, I/A Series time synchronization, and hot standby function; BNC supports TriStation, TSAA protocol, and user applications; Multiple ports (BNC, 15 pin D-type AUI, 9-pin RS-423 Nodebus control port, etc.), some ports have a speed of 10 Mbps, the Nodebus control port is 2400 baud, the power load is 20 watts, isolated 500 VDC, and equipped with multiple status indicator lights.

Communication Protocol and Application

Support agreement: TriStation、Modbus（RTU/ASCII/TCP）、TCP/IP、ICMP、SNTP、TSAA、Trimble GPS、 Peer to Peer, peer-to-peer time synchronization, Jet Direct (network printing), etc.

Triconex protocol: Peer to peer protocol (exchanging security and process information between Tricons), time synchronization protocol (maintaining Tricon time consistency in the network), TriStation protocol (master-slave communication between TriStation PC and Tricon, one slave per communication), TSAA protocol (master-slave communication between external hosts and Tricon, used for developing control or monitoring applications).

Triconex applications: TriStation 1131 (for developing, testing, and monitoring Tricon applications), Event Sequence (SOE, for retrieving Tricon events in the network for maintenance and downtime analysis), Enhanced Diagnostic Monitor (for monitoring Tricon hardware and application status), DDE Server (for allowing Windows DDE clients such as Excel to read and write Tricon alias data), OPC Server for Triconex (for allowing OPC clients to read and write Tricon program variables, some modules rely on external Matrikon OPC Server, and some models will have embedded OPC Server).

Network redundancy and configuration rules

Module/Media Redundancy: Install two communication modules (TCM/NCM/ACM) in the same logical slot and connect network nodes with two sets of cables to address issues such as cable breakage and port failures.

External host redundancy: The backup external host is connected to the network, and in the event of a primary host failure, the control program can be restarted on the backup host. All Triconex applications can be loaded onto the primary and backup hosts.

Configuration rule: TriStation PC needs to communicate with Tricon through TCM/EICM/NCM/ACM, and at least one such module needs to be installed in the main Chassis or Chassis 2; Some modules (such as EICM, ACM) have a limit on the number of logical slots, and some modules (such as NCM, TCM) cannot coexist in the same system; If Chassis 2 is equipped with a communication module, it requires an I/O COMM cable (9001 model) instead of a standard I/O bus cable to directly connect to the main Chassis. Chassis 2 can be an I/O expansion Chassis or a main RXM Chassis.

TriStation 1131 Development Platform and Programming

TriStation 1131 Developer’s Workbench

Positioning and compatibility: an integrated tool for developing, testing, and documenting Tricon's safety and critical process control applications, compliant with the IEC 61131 international standard and following the Microsoft Windows graphical user interface guidelines; Different versions have different compatibility, such as v4.1.433 and above being compatible with Tricon 9.5.x-10.1. x, v4.1 supporting Windows NT/2000/XP, v4.0 only supporting Windows NT/2000 (only verifying Windows 2000), and versions below v4.0 only supporting Windows NT.

Core function: Provides three IEC 61131-3 language editors: Function Block Diagram (FBD), Ladder Diagram (LD), and Structured Text (ST), with optional CEMPLE language editor (supporting causal matrix method); Can create programs, functions, function blocks, define controller configurations, declare tag names, test applications in simulators, download and monitor applications.

V4.1 new feature: compatible with Windows 2000/XP; Support the setup of new analog input, digital output, and Tricon communication modules; Automatically save backup project files after downloading, which can be used for recovery; Support writing intermediate ST code to files; The enhanced diagnostic monitor has become an independent application since v4.1.435.

Project Elements and Programming Languages

Project elements: program (highest level executable logic element, one project can support hundreds), function (produces a single result, data is not retained), function block (produces one or more results, needs instantiation, data is retained), data type (defines variable size and characteristics, such as BOOL, DINT, REAL), library (including IEC 61131-3 standard library, Triconex library, Tricon library, user can create custom libraries).
