3500-22M 接口模块  通信处理器的数据收集功能

3500/22M 数据接口模块是 3500 监控系统和兼容软件（系统 1* 状态监控和诊断软件以及 3500 系统配置软件）之间的接口。TDI 结合了 3500/20 机架接口模块 (RIM) 的功能和通信处理器（如 TDXnet）的数据收集功能。

TDI 位于与 3500 机架的电源相邻的插槽中。它与 M 系列监视器（3500/40M、3500/42M 等）连接，以连续收集稳态和瞬态动态（波形）数据，并通过以太网链路将这些数据传递到主机软件。

瞬态数据捕获能力是 TDI 的标准配置。然而，使用可选的通道启用磁盘将允许 TDI 捕获动态和高分辨率瞬态数据。TDI 在 3500 机架中集成了通信处理器功能。

虽然 TDI 提供了整个机架共有的某些功能，但它不是关键监控路径的一部分，并且不会影响用于自动机械保护的整体监控系统的正确、正常运行。每个 3500 机架需要一个 TDI 或 RIM，它们始终占用插槽 1（电源旁边）。

The 3500/22M data interface module is the interface between the 3500 monitoring system and compatible software (System 1* status monitoring and diagnostic software and 3500 system configuration software). The TDI combines the capabilities of a 3500/20 rack interface module (RIM) with the data collection capabilities of a communications processor such as TDXnet.

The TDI is located in a slot adjacent to the power supply of the 3500 rack. It connects with M-series monitors (3500/40M, 3500/42M, etc.) to continuously collect steady-state and transient dynamic (waveform) data and pass this data to the host software via an Ethernet link.

Transient data capture capability is standard in TDI. However, enabling the disk with an optional channel will allow TDI to capture dynamic and high-resolution transient data. TDI integrates communication processor capabilities in 3500 racks.

While TDI provides certain features common to the entire rack, it is not part of the critical monitoring path and does not affect the correct and proper operation of the overall monitoring system for automated mechanical protection. Each 3500 rack requires a TDI or RIM, which always occupy slot 1 (next to the power supply).
