TRICONEX 3301 控制器卡件
TRICONEX 3301 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,而不是整个模块故障。DI模块持续验 证系统检测向相反状态转变的能力。DI模块保证在出现单个故障时正常运行,并粗在出现多个故障时也能继续正常运行。DI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DI模块可用于以下基板:2301型, 用于典型应用。DI外部终端基板,用于 高压应用中的固态继电器输入外部终端面板,或9573-610型DI危险场所外部终端面板。第二级网络是控制器之间的通讯,把完成不同任务的三种控制器连在一条总线上,称为控制总线。在控制总线上的不同控制器的数量不受限制。在这一条总线上除三种不同的控制器模件以外,还有DCS网络的接口模件。在控制总线上,控制器之间可以调用数据。使得模拟量和开关量之间的结合很好。控制总线不是每一种DCS系统都有的,可以把各种控制器分别连到DCS网络上。控制器之间的数据调用要通过DCS网络。控制总线的速率情况与I/O总线的情况相类似。通常是几十K到几兆之间。当CPU和存储器的能力比较强时,把开关量的逻辑运算和模拟量的采集功能都在一个控制器中完成。在控制总线上就只有一种形式的控制器。其协议采用载波监听,广播发送,类似以太网的协议。

TRICONEX 3301 controller card Each TMR digital input module has three groups of isolated electronic devices, called channels, which independently process the field data of the module. Each channel puts the processed data in an array and transmits the array to the MP associated with the channel according to the request. MPs votes on the data before passing it to the application. DI module includes complete and continuous diagnosis of each channel. If the diagnostics detects a fault on any channel, the fault indicator lights up and activates the system alarm. The fault indicator identifies the channel fault, not the whole module fault. DI module continuously verifies the ability of the system to detect the transition to the opposite state. DI module can guarantee normal operation in case of single fault, and can continue normal operation in case of multiple faults. DI module supports hot standby module. Each DI module is mechanically locked to prevent improper installation in the configured substrate. Model 3301 DI module can be used for the following substrates: Model 2301 for typical applications. DI external terminal board, used for solid-state relay input external terminal panel in high-voltage application, or 9573-610 DI dangerous place external terminal panel.
The second-level network is the communication between controllers, which connects three controllers that accomplish different tasks on a bus, which is called control bus. The number of different controllers on the control bus is not limited. In addition to three different controller modules, there are also interface modules of DCS network on this bus. On the control bus, data can be called between controllers. So that the combination between analog quantity and switching quantity is very good. The control bus is not available in every DCS system, and various controllers can be connected to the DCS network respectively. The data call between controllers should go through DCS network. The speed of the control bus is similar to that of the I/O bus. Usually it is between tens of k and several megabytes. When the capabilities of CPU and memory are relatively strong, the logical operation of switching value and the acquisition function of analog quantity are completed in one controller. There is only one form of controller on the control bus. Its protocol adopts carrier monitoring, broadcast transmission, similar to Ethernet protocol.
