Description

BENTLY 3500/20 125744-02
The Rack Interface Module (RIM) is the primary interface to the
3500 rack. It supports a proprietary protocol used to
configure the rack and retrieve machinery information. The
RIM must be located in slot 1 of the rack (next to the power
supplies).
The RIM supports compatible Bently Nevada external
communications processors such as TDXnet, TDIX, and DDIX.
While the RIM provides certain functions common to the
entire rack, the RIM is not part of the critical monitoring path
and has no effect on the proper, normal operation of the
overall monitoring system. One RIM is required per rack.
For Triple Modular Redundant (TMR) applications, the 3500
System requires a TMR version of the RIM. In addition to all the
standard RIM functions, the TMR RIM also performs “monitor
channel comparison.” The 3500 TMR configuration
implements monitor voting using the setup specified in the
monitor options. Using this method, the TMR RIM continually
compares the outputs from three (3) redundant monitors. If
the TMR RIM detects that the information from one of those
monitors is no longer within a configured percentof the
information of the other two monitors, it will flag that the
monitor is in error and place an event in the System Event List.
