TRICONEX 3351  模拟输入模块

Tricon是一种高容错的可编程和过程控制技术。TRICONEX 3351  模拟输入模块其特点如下:提供三模冗余结构(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。还有一个专用的硬件/软件架构,用于对输入和输出进行能够忍受恶劣的工业环境。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。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网络中的外部主可以支持距离大型机最远12公里的远程I/O模块。TRICONEX 3351  模拟输入模块使用基于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可减少主处理器的工作负荷。每个/O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。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。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 。

Tricon is a highly error tolerant programmable and process control technology. The characteristics of TRICONEX 3351 analog input module are as follows: the third mock examination Redundancy (TMR) is provided, with three identical sub circuits, and each sub circuit performs independent control. There is also a dedicated hardware/software architecture for input and output that can withstand harsh industrial environments. It can be installed on-site and can be installed and repaired at the module level online without interfering with on-site wiring. Supports up to 118 I/O modules (analog and digital) and optional communication modules. The communication module can be connected to Modbus: host and slave devices, or Foxboro and Honeywell distributed control systems (DCS), other Tricons in peer-to-peer networks, and external hosts in TCP/IP networks can support remote I/O modules up to 12 kilometers away from the mainframe. The TRICONEX 3351 analog input module uses programming software based on the Windows NT system to develop and debug control programs. The intelligent functions in the input and output modules can reduce the workload of the main processor. Each/O module has three microprocessors. The microprocessor of the input module filters and repairs inputs, and diagnoses hardware faults on the module. 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. Provide comprehensive online diagnosis and repair capabilities. When Tricon starts and runs, daily maintenance can be carried out without interrupting the control process. Provide "hot standby" support for I/O modules, which can be used in emergency situations where services cannot be provided in a timely manner.
