TRICONEX DI3301 英维思 SIS系统备件 数据通信模块

数字输入模块每个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,并且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。

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 a channel fault, not an entire module fault.

The DI module continuously validates the system's ability to detect transitions to the opposite state. The DI module is guaranteed to function properly in the event of a single failure and continue to function properly in the event of multiple failures. The DI module supports the hot standby module.
