- TDI 带有内置的静态数据捕获功能。但是，通道启用磁盘是一种可选设备，使TDI也能够记录动态和高分辨率瞬态数据。3500机架包含TDI的通信处理功能。
- 3500/22M 系列瞬态数据接口将 3500 监控系统连接到本特利内华达的 System 1 机械管理软件。TDI 将 3500/20 机架接口模块的功能与 TDXnet 等通信处理器的数据收集功能相结合。
- TDI 与 M 系列监视器（3500/3500M、40/3500M 等）一起在 42 机架的 RIM 插槽中工作，以连续捕获稳态和瞬态波形数据，并通过以太网链路将其传输到主机软件。默认情况下，TDI 捕获静态数据，但安装额外的通道启用磁盘也可以记录动态或瞬态数据。
- 除了在 3500 机架中实现通信处理器功能外，TDI 还在多个方面比以前的通信处理器进行了增强。
- TDI 执行整个机架共享的某些功能;然而，TDI不是关键监测通道的一部分，对整个监测系统的正确、正常性能没有影响。每个机架需要一个 TDI 或 RIM。TDI 仅占用机架中的一个插槽，并且始终处于 Slo t 1 中。（在电源旁边）。
- 3500 系统需要 TMR 版本的 TDI 用于三重模块化冗余 （TMR） 应用。TMR TDI 除了执行所有常规 TDI 功能外，还执行“监控通道比较”。监控投票由 3500 TMR 配置利用监控选项中提供的安排进行。使用这种方式，TMR TDI实时比较三个冗余监视器的输出。
- 如果 TMR 确定来自其中一个监视器的信息不再等于（在指定的百分比内）来自其他两个监视器的信息，它将标记该监视器为错误，并在系统事件列表中记录事件。

TDI comes with built-in static data capture function. However, channel enabled disks are an optional device that enables TDI to also record dynamic and high-resolution transient data. The 3500 rack contains communication processing functions for TDI.
The 3500/22M series transient data interface connects the 3500 monitoring system to Bently Nevada’s System 1 mechanical management software. TDI combines the functions of the 3500/20 rack interface module with the data collection functions of communication processors such as TDXnet.
TDI works together with M-series monitors (3500/3500M, 40/3500M, etc.) in the RIM slot of the 42 rack to continuously capture steady-state and transient waveform data, and transmit it to the host software through an Ethernet link. By default, TDI captures static data, but installing additional channel enabled disks can also record dynamic or transient data.
In addition to implementing communication processor functionality in the 3500 rack, TDI has also been enhanced in multiple aspects compared to previous communication processors.
TDI performs certain functions shared across the entire rack; However, TDI is not a part of the critical monitoring channel and has no impact on the correct and normal performance of the entire monitoring system. Each rack requires a TDI or RIM. TDI only occupies one slot in the rack and is always in Slot 1. (next to the power supply).
The 3500 system requires a TMR version of TDI for Triple Modular Redundancy (TMR) applications. TMR TDI not only performs all regular TDI functions, but also performs “monitoring channel comparison”. The monitoring voting is carried out using the arrangements provided in the monitoring options in the 3500 TMR configuration. Using this method, TMR TDI compares the outputs of three redundant monitors in real-time.
If TMR determines that the information from one monitor is no longer equal (within the specified percentage) to the information from the other two monitors, it will mark that monitor as an error and record the event in the system event list.
