Triconex Tricon控制系统简介：

Tricon控制系统的主要特点Tricon是一种具有高容错性的可编程和过程控制技术。

其特点如下：

提供三模块冗余结构（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。还有一个硬件/软件架构，用于对输入和输出进行“投票”。能够承受恶劣的工业环境。

可在现场安装，并可在现场在线安装和维修模块级，而不干扰现场布线。

支持多达118个I/O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Tricon以及TCP/IP网络上的外部主机。

可以支持距离大型机12公里的远程I/O模块。

使用基于Windows NT系统的编程软件开发和调试控制程序。

输入和输出模块中的智能功能，以减少主处理器的工作量。每个I/O模块有三个微处理器。输入模块的微处理器过滤并修复输入，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，并可以诊断现场线路问题。

提供在线诊断和维修能力。

可在Tricon启动和运行时执行常规维护，而不中断控制过程。

为I/O模块提供“热备用”支持，可用于无法及时提供服务的某些关键情况。

Brief introduction of Triconex Tricon control system;

Tricon is a programmable and process control technology with high fault tolerance.

Its characteristics are as follows:

A three-module redundancy structure (TMR) is provided, which has three identical sub-circuits, and each sub-circuit performs independent control. There is also a hardware/software architecture for "voting" on inputs and outputs. Able to withstand harsh industrial environment.

It can be installed in the field, and the module level can be installed and maintained online in the field without disturbing the field wiring.

Support up to 118 I/O modules (analog and digital) and optional communication modules. The communication module may

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

Can support remote I/O modules 12 kilometers away from the mainframe.

Use the programming software based on Windows NT system to develop and debug the control program.

Intelligent functions in input and output modules to reduce the workload of the main processor. Each I/O module has three microprocessors. The microprocessor of the input module filters and repairs the input and diagnoses the hardware fault on the module. The output module microprocessor provides information for the voting of output data, checks the validity of the output state through the feedback loop voltage at the output end, and can diagnose the field line problem.

Provide online diagnosis and maintenance capabilities.

Routine maintenance can be performed while Tricon is up and running without interrupting the control process.

Provide "hot standby" support for I/O modules, which can be used in some key situations where services cannot be provided in time.
