Description
The 3500/22M Transient Data Interface (TDI) is the interface
between the 3500 monitoring system and compatible
software (System 1 Condition Monitoring and Diagnostic
software and 3500 System Configuration software). The TDI
combines the function of a 3500/20 Rack Interface Module(RIM) with the data collection capability of a communication
processor such as TDXnet.
The TDI resides in the slot adjacent to the power supplies of a3500 rack. It interfaces with M series monitors (3500/40M,3500/42M, etc.) to continuously collect steady state andtransient dynamic (waveform) data and pass this data
through an Ethernet link to the host software. Refer to theCompatibility section at the end of this document for moreinformation.
Static data capture capability is standard with the TDI.
However, using an optional Channel Enabling Disk will allow
the TDI to capture dynamic and high-resolution transient
data as well. The TDI incorporates the communication
processor function within the 3500 rack.
Although the TDI provides certain functions common to theentire rack, it is not part of the critical monitoring path andhas no effect on the proper, normal operation of the overallmonitor system for automatic machinery protection. Every
3500 rack requires one TDI or RIM, which always occupies
Slot 1 (next to the power supplies).

Configuration
Keylock

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

Alarm Data Collection

Both versions of the TDI I/O Module now include
a 2-pin connector for connecting Signal
Common to a single point Instrument Groundfor the rack. When this is done, the selector
switch on the side of the Power Input Module(PIM) must be slid in the direction of the arrow
marked "HP" to isolate Signal Common fromchassis (safety) ground.

Pre- and post-alarm data

3500 22M Dynamic Data Enabling
Disk

Network Requirements

This disk enables the number of channels ofdynamic data (i.e., the ability to collectwaveforms) that the TDI will support. There are
two levels of dynamic data. Steady-State
points are channels that collect waveform data
due either to a software command or to an
alarm event, and therefore support current
values, scheduled waveform capture, andalarm data capture. Transient points provide all
the function of a Steady-State point with theadditional capability of waveform collection
due to parameter variations such as machine
speed.

For complete information on network
requirements, refer to the 3500 Hardening
Guide [document 106M9733]. This document
can be requested at BNTechsupport.com.
