9853-610 模拟量输出端子板

描述

9853-610 模拟量输出端子板

TRICONEX的特点

为了保证在任何时候系统都有最高的完整性，

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、以及在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。

—-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。

—-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I/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最后有效、并能诊断现场线路的问题。

—-提供总体的在线诊断，并具有自适应修理能力。

—-可以在TRICONEX正常运行中进行常规维护而不干扰被控的过程。

—-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。

Features of TRICONEX

To ensure the highest system integrity at all times,

With a triple combined redundancy structure, each of the three identical system branches can execute the control program independently. There is also a dedicated hardware/software mechanism to “vote” on inputs and outputs. Withstand harsh industrial environments. It can be installed in the field and can be repaired at the module level when the controller is in online use. I/O module replacement does not disrupt the field wiring. Supports up to 118 I/O modules (analog and digital) and optional communication modules that can be connected to Modbus hosts and slaves. Or connect to FoxboroHoneywell Distributed Control System (DCS), other Tricons within the peer-to-peer network, and external hosts on the 802.3 network.

– Combined support for remote I/O modules located up to 2 km (1.2 mi) from the main frame.

A control program can be executed that is written in relay cascade logic and is evolved and debugged by an independent workstation called TRISTATION.

Intelligent functions are built into the input and output modules to reduce the workload of the main processor, and each I/O module has three microprocessors. The input module’s microprocessor filters and demodulates the input and diagnoses hardware failures on the module. The output module microprocessor provides information for voting on the output data, checks the loopback data from the output terminal to make the output final valid, and can diagnose problems with the field line.

— Provides total online diagnostics with adaptive repair capabilities.

Routine maintenance can be performed during normal TRICONEX operation without interfering with controlled processes.

– Supports the use of “hot swappable Spare parts” I/O modules at critical times, in cases where immediate repair is not possible.
