Description:

The 3500 Transient Data Interface (TDI) is the interface between the 3500 monitoring system and Bently Nevada’s System 1® machinery management software. The TDI combines the capability of a 3500/20 Rack Interface Module with the data collection capability of a communication processor such as TDXnet. TDI operates in the RIM slot of a 3500 rack in conjunction with the M series monitors (3500/40M, 3500/42M, etc.) to continuously collect steady state and transient waveform data and pass this data through an Ethernet link to the host software. Static data capture is standard with the TDI, however using an optional Channel Enabling Disk will allow dynamic or transient data to be captured as well. TDI has made improvements in several areas over previous communication processors in addition to incorporating the Communication Processor function within the 3500 rack.

TDI provides certain functions common to the entire rack, however the TDI is not part of the critical monitoring path and has no effect on the proper, normal operation of the overall monitor system. One TDI or RIM is required per rack. The TDI occupies only a single slot in the rack and is always located in Slot 1 (next to the power supplies).

For Triple Modular Redundant (TMR) applications, the 3500 System requires a TMR version of the TDI. In addition to all the standard TDI functions, the TMR TDI also performs “monitor channel comparison”. The 3500 TMR configuration executes monitoring voting using the setup specified in the monitor options. Using this method, the TMR TDI continually compares the outputs from three (3) redundant monitors. If the TMR detects that the information from one of those monitors is no longer equivalent (within a configured percent) to the remaining two, it will flag the monitor as being in error and place an event in the System Event List.

Used to place 3500 rack in either “RUN” mode or “PROGRAM” mode. RUN mode allows for normal operation of the rack and locks out configuration changes. PROGAM mode allows for normal operation of the rack and also allows for local or remote rack configuration. The key can be removed from rack in either position, allowing switch to remain in either RUN or PROGRAM position. Locking switch in the RUN position allows you to restrict unauthorized rack reconfiguration. Locking switch in PROGRAM position allows remote reconfiguration of a rack at any time.

Relay to indicate when the 3500 rack is operating normally or when a fault has been detected within the rack. User can select either an “OPEN” or “CLOSED” contact to annunciate a NOT OK condition. This relay always operates as “Normally Energized”.

This disk is used to enable the number of channels of dynamic data that the TDI will support; dynamic data refers to the ability to collect waveforms. There are two levels of dynamic data: Steady-State points are channels that collect waveform data either due to a software command or due to an alarm event, and therefore support current values, scheduled waveform capture, and alarm data capture. Transient points provide all the function of a Steady-State point with the additional capabilities of waveform collection due to parameter variations such as machine speed.
