TRICONEX英维思3721模拟输入控制模块工业通信

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。

Its characteristics are as follows:

Provides a three-module redundant structure (TMR) with three identical subcircuits, each performing an independent degree of control. There is also a hardware/software architecture for "voting" on inputs and outputs. Able to withstand harsh industrial environments.

It can be installed in the field, and module levels can be installed and serviced online in the field without interfering with field wiring.

Up to 118 I/O modules (analog and digital) and optional communication modules are supported. Communication module can

Connect to Modbus hosts and slave devices, or to Foxboro and Honeywell Distributed Control Systems (DCS), other Tricons in peer-to-peer networks, and external hosts on TCP/IP networks.

It can support remote I/O modules up to 12 km from the mainframe.

Develop and debug control programs using programming software based on Windows NT systems.

Intelligent functions in input and output modules to reduce the workload of the main processor. Each I/O 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 status by the feedback loop voltage at the output, and can diagnose field line problems.
