Tricon控制系统的主要特点
Tricon是一种高容错的可编程和过程控制技术。
其特点如下:
A.提供三模几余结构(TMR ),具有三个相同的子电路，每个子电路执行独立程度的控制。还有一个专用的硬件/软件架构，用于对输入和输出进行“表决”

3351

能够忍受恶劣的工业环境.C.它可以在现场安装，并且可以在不干扰现场布线的情况下在现场在线安装和修复模块级。D.支持多达118个I/0模块(模拟和数字)和可选通信模块。通信模块可以连接到Modbus主机和从属设备，或连接到Foxboro和Honeywell分布式控制系统DCS)，对等网络中的其他Tricons，以及TCP/IP网络中的外部主机。
E.可以支持距离大型机最远12公里的远程I/O模块。F.使用基于Windows NT系统的编程软件开发和调试控制程序。G.输入和输出模块中的智能功能可减少主处理器的工作负荷。每个/0模块有三个微处理器。输入模块的微处理器过滤和修复输入，并诊断模块上的硬件故障。输出模块微处理器为输出数据的表决提供信息，通过输出端的反馈回路电压检查输出状态的有效性，并能诊断场线问题。
H.提供全面的在线诊断和修复能力。
Tricon启动和运行时，可以进行日常维护，而不会中断控制过程J.为I/O模块提供“热备用”支持，可用于某些无法及时提供服务的紧急情况。

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 multi-remainder structure (TMR) with three identical subcircuits, each performing an independent degree of control. There is also a dedicated hardware/software architecture for “voting” on 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. Supports up to 118 I/0 modules (analog and digital) and optional communication modules. Communication modules can be connected to Modbus hosts and slave devices, or to Foxboro and Honeywell Distributed Control System DCS), other Tricons in peer-to-peer networks, and external hosts in TCP/IP networks.
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 /0 module has three microprocessors. The input module’s microprocessor filters and repairs the input and diagnoses hardware failures on the module. 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.
When Tricon is up and running, routine maintenance can be performed without interrupting the control process. Provides “hot standby” support for I/O modules, which can be used in certain emergency situations where service cannot be provided in time.
