The 3500/22M Transient Data Interface (TDI) is the interface between the 3500 monitoring System and the Bentley Nevada System 1TM machine management software. TDI separates the functions of 3500/20 framework interface modules (RIM) and communication handlers such as TDXnet. The TDI operates in the RIM slot of the 3500/22M frame and is used in conjunction with the M series monitor (3500/40M, 3500/42M, etc.) to continuously collect steady-state and transient waveform data and transmit the data to the main computer software over Ethernet. TDI has standard static data acquisition, but enables the disk to capture transient or dynamic data using an optional channel. In addition to integrating the functionality of the communication handler into the 3500 framework, TDI offers several improvements over previous communication handlers. TDI provides general functionality to the framework, but is not part of the critical monitoring channel and does not affect the correct and routine operation of the overall monitoring system. Each frame pleads for a TDI or RIM. The TDI occupies only one slot in the frame and must be located in a slot next to the power module. Regarding triple module redundancy (TMR) applications, the 3500 system begs the TMR mode of TDI. In addition to the functions of standard TDI, TMR TDI also has a “monitor channel comparison function”. After the installation function of selecting the monitor option, the 3500TMR configuration performs the monitoring voting function. In this way, TMR TDI continuously compares the output of three redundant monitors.
