详细介绍


3700A   模拟输入模块

一、Tricon的特点
为了保证在任何时候系统都有高的完整性,TRICON-sis系统有如下特点:备有三重组合式冗余结构,三个完全相同的系统分支的每一个都能独 立地执行控制程序。而且备有专用的硬件/软件机制,可对输入和输出进行"表决”。能耐受严酷的工业环境。能够现场安装,可以在控制器在线使用状态下进行模件一级的修理工作。I/O模件的更换不会打乱现场布线。能支持多达118个I/O模件(模拟的和数字的)和选装的通讯模件,该模件可以与Modbus主机和从属机连接,或者和FoxboroHoneywell分布控制系统(DCS)、其它在Peer- -to- Peer网络内的各个TRICON、 以吸在802.3网络 上的外部主机相连接。备有组合的支持, 可以支持位于远离主机架2公里(1.2英里)以内的远距I / O模件。
一-可以执行控制程序,该程序按继电器梯级逻辑写成并由一独立的称作TRISTATION的工作站进行演变和调试。
一-在输入和输出模件内备有 智能功能,以使主处理器的工作负荷得以减轻,每个/O模件都有三个微处理器。输入模件的微处理器对输入进行过滤和解调,并诊断模件上的硬件故障。输出模件微处理器为输出数据的表决提供信息、检查来自输出终端的环回数据以使输出能后有效、并能诊断现场线路的问题。
一提供总体的在线诊断, 并犋有自适应修理能力。
一-可以在TRICON正常运行中进行常规维护而不干扰被控的过程。
一可支持 “热插备件”I/O模件在关键时候的使用,在不可能立即进行维修的情况下应急。

1、 Characteristics of Tricon
In order to ensure the highest integrity of the system at all times, the TRICON sis system has the following characteristics: it has a triple combined redundant structure, and each of the three identical system branches can independently execute control programs. And it is equipped with dedicated hardware/software mechanisms, Can 'vote' on inputs and outputs. Can withstand harsh industrial environments. Can be installed on-site and perform module level repair work while the controller is in online use. Replacement of I/O modules does not disrupt field wiring. Can support up to 118 I/O modules (analog and digital) and optional communication modules, which can be connected to Modbus hosts and slaves, or FoxboroHoneywell distributed control system (DCS) Other TRICONs within the Peer to Peer network are connected to external hosts attached to the 802.3 network. Equipped with combination support, it can support remote I/O modules located within 2 kilometers (1.2 miles) away from the main frame.
One can execute a control program, which is written according to relay cascade logic and is evolved and debugged by an independent workstation called TRISTATION.
There are intelligent functions within the input and output modules to reduce the workload of the main processor. Each/O module has three microprocessors. The microprocessor of the input module filters and demodulates the input, and diagnoses hardware faults on the module. The output module microprocessor provides information for the voting of output data, checks the loopback data from the output terminal to ensure that the output is finally effective, and can diagnose on-site circuit problems.
Provide overall online diagnosis and possess adaptive repair capabilities.
One can perform routine maintenance during the normal operation of TRICON without interfering with the controlled process.
One can support the use of "hot swappable spare parts" I/O modules at critical times, in emergency situations where immediate maintenance is not possible.
