Bently Nevada 3500/20 Enhanced bond phase module

The 3500 transient data interface (TDI) is the interface between the 3500 monitoring system and the Bently Nevada system 1 mechanical management software. TDI combines the functions of 3500/20 rack interface modules (RIMS) and communication processors such as tdxnet. The TDI runs in the rim slot of the 3500 rack and works with M series monitors (3500/40m, 3500/42m, etc.) to continuously collect steady-state and transient waveform data and transmit the data to the host computer software via Ethernet. TDI has standard static data acquisition, but uses optional channel enabled disks, and can also collect transient or dynamic data. Compared with the previous communication processors, TDI has several other improvements besides integrating the functions of the communication processor into the 3500 rack. TDI provides general functions for the framework, but it is not an integral part of the key monitoring channel and does not affect the correct and routine operation of the entire monitoring system. Each frame requires a TDI or rim. The TDI occupies only one slot in the frame and must be located in one slot (next to the power module). For triple modular redundancy (TMR) applications, 3500 systems require TDI in the form of TMR. In addition to the functions of the standard TDI, the TMR TDI also has a “monitor channel comparison function”. The 3500tmr configuration performs the monitoring voting function by selecting the installation function of the monitor option. In this way, the TMR TDI continuously compares the outputs of the three redundant monitors. If the TMR TDI detects that the output information of one monitor is not equal to that of the other two monitors (within the configured percentage), it will send an error indication to the monitor.
