The main characteristics of the Tricon control system

Tricon is a highly error tolerant programmable and process control technology.

Its characteristics are as follows:

A. The third mock examination redundant structure (TMR) is provided, which has three identical sub circuits, and each sub circuit performs independent control. There is also a dedicated hardware/Software architecture for "tabulating" inputs and outputs

Able to tolerate harsh industrial environments.

C. It can be installed on-site and can be installed and repaired at the module level online without interfering with on-site wiring.

D. Supports up to 118/O modules (analog and digital) and optional communication modules. The communication module can

Connect to Modbus hosts and slave devices, or connect to Foxboro and Honeywell distributed control systems (DCS), other Tricons in peer-to-peer networks, and external hosts in TCP/IP networks

Machine.

E. It can support remote I/O modules up to 12 kilometers away from the mainframe.

F. Develop and debug control programs using programming software based on the Windows NT system.

G. The intelligent functions in the input and output modules can reduce the workload of the main processor. Each I/O module has three microprocessors. The microprocessor of the input module filters and repairs inputs, and diagnoses faults on the module

Hardware failure. The output module microprocessor provides information for the voting of output data, checks the effectiveness of output status through the feedback circuit voltage at the output end, and can diagnose field line problems.

H. Provide comprehensive online diagnosis and repair capabilities.

1. When Tricon starts and runs, daily maintenance can be carried out without interrupting the control process.

J. Provide "hot standby" support for I/O modules, which can be used in certain emergency situations where services cannot be provided in a timely manner.
