3301 TRICONEX 控制器卡件

3301 TRICONEX 控制器卡件每个TMR数字输入模块都有三组隔离的电子设备，称为通道，它们独立处理模块的现场数据。每个通道将处理后的数据放在一个数组中，并根据请求将该数组传输到与该通道相关联的MP。MPs在将数据传递给应用程序之前对其进行表决。DI模块包括每个通道的完整、持续的诊断。如果诊断程序在任何通道上检测到故障，故障指示灯会亮起并激活系统警报。故障指示器识别通道故障，而不是整个模块故。D模块持续验证系统检测向相反状态转变的能力。D|模块保证在出现单个故障时正常运行，并且在出现多个故障时也能继续正常运行。D模块支持热备用模块。每个DI模块都是机械锁定的，以防止在已配置的基板中安装不当。3301型D|模块可用于以下基板:2301型，用于曲型应用。D1外部终端基板，用于高乐应用中的固态然器输入外部终端面板，或9573-610型DI危险场所外部终端面板

3301 TRICONEX Controller Card Each TMR digital input module has three separate sets of electronics, called channels, that independently process the module’s field data. Each channel places the processed data in an array and transfers that array to the MP associated with that channel upon request. MPs votes on the data before passing it to the application. The DI module includes complete, continuous diagnostics for each channel. If the diagnostic detects a fault on any channel, the fault indicator lights up and activates the system alert. The fault indicator identifies the channel fault, not the entire module fault. The D module continuously validates the system’s ability to detect transitions to the opposite state. The D| module is guaranteed to function in the event of a single failure and to continue to function in the event of multiple failures. The D module supports the hot standby module. Each DI module is mechanically locked to prevent improper installation in the configured substrate. The Model 3301 D| module is available on the following substrates: Model 2301 for curved applications. D1 External terminal substrate for solid-state input external terminal panels in Gauller applications, or Type 9573-610 DI hazardous site external terminal panels
Key features of the Tricon control system
Tricon is a highly fault-tolerant programmable and process control technology
Its characteristics are as follows:
A, provides a three-mode multi-remainder structure (TMR) with three identical subcircuits, each performing an independent degree of control. There is also a dedicated hardware/software architecture for “voting” on inputs and outputs
Able to endure harsh industrial environments.
C. It can be installed in the field and module level D can be installed and repaired online in the field without interfering with the field wiring. Up to 118 I/O modules (analog and digital) and optional communication modules are supported. Communication modules can be connected to Modbus hosts and slave devices, or to Foxboro and Honeywel Distributed control Systems (DCS), other Tricons in peer-to-peer networks, and external hosts in TCP/IP networks.
E. Can support remote I/O modules up to 12 km from the mainframe.
F. Develop and debug control programs using programming software based on Windows NT systems. G. Intelligent functions in the input and output modules reduce the workload of the main processor. Each /0 module has three microprocessors. The input module’s microprocessor filters and repairs the input and diagnoses hardware failures on the module, the output module’s microprocessor provides information for voting on the output data, checks the validity of the output state by the feedback loop voltage at the output, and can diagnose field line problems.
H. Provide comprehensive online diagnostic and repair capabilities.
When Tricon is up and running, routine maintenance can be performed without interrupting the control process.
J. Provide “hot backup” support for I/O modules, which can be used in certain emergency situations where service cannot be provided in time.

Tricon控制系统的主要特点
Tricon是一种高容错的可编程和过程控制技术
其特点如下:
A,提供三模几余结构(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“表决”
能够忍受恶劣的工业环境.
C.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D.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Honeywel分布式控制系统(DCS)，对等网络中的其他Tricons，以及TCP/IP网络中的外部主机。
E.可以支持距离大型机最远12公里的远程I/O模块。
F.使用基于Windows NT系统的编程软件开发和调试控制程序。G.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/0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。
H.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.
J.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。
