Key features of the Tricon control system
Tricon is a highly fault-tolerant programmable and process control technology.
Its characteristics are as follows:
A. Provide a three-mode redundant structure (TMR) with three identical subcircuits, each performing an independent degree of control. There is also a dedicated hardware/software architecture for tabulating inputs and outputs
Able to endure harsh industrial environments.
C. It can be installed in the field, and module levels can be installed and repaired online in the field without interfering with the field wiring.
D. Support up to 118 /O modules (analog and digital) and optional communication modules. Communication module can
Connect to Modbus hosts and slave devices, or to Foxboro and Honeywell Distributed Control Systems (DCS), other Tricons in peer-to-peer networks, and external masters in TCP/IP networks
Airplane.
E. Can support remote I/O modules up to 12 km from the mainframe.
F. Develop and debug control programs using programming software based on Windows NT systems.
G. Intelligent functions in the input and output modules reduce the workload of the main processor. Each I/O module has three microprocessors. The input module's microprocessor filters and repairs the input, and diagnoses the module on it
The hardware is faulty. The output module microprocessor provides information for the voting of the output data, checks the validity of the output state by the feedback loop voltage at the output, and can diagnose field line problems.
H. Provide comprehensive online diagnostic and repair capabilities.
1. When Tricon is up and running, routine maintenance can be carried out without interrupting the control process.
J. Provide "hot backup" support for I/O modules, which can be used in certain emergency situations where service cannot be provided in time.
