Bently Nevada Machinery Condition Monitoring

149831 Rev. AF

Description
The 149744 Trendmaster Dynamic Scanning Module (DSM) is acompact rack-based data acquisition system that is fully
integrated with System 1 software. The DSM rack has a total of
5 card slots. The first slot is dedicated for communications
and will accept either the copper or fiber Ethernet card. The
second slot is reserved. The 3rd to 5th slots are TIM Input cardor reserved.
The TIM input card connects to Bently Nevada TIM and proTIMmodules. Each TIM input card provides 2 TIM lines, and each
TIM line supports up to 254 channels. Input cards offer highresolution sampling with onboard real-time processing.
Onboard processing is the key to the powerful and efficientfeatures available with the DSM platform. Because each input
card can process data locally, the DSM can return postprocessed variables to the host computer and reduce therequired network bandwidth. If the host computer requires
raw data, the DSM can also return waveforms and spectrums.

Modbus Communications Capability
The introduction of a Modbus digital interface now permits
DSMs to communicate directly with process control andautomation systems without the need for additional
hardware. This capability provides a low-cost entry-level
alternative to System 1 that uses the basic trending andalarming functionality that is integral to existing processcontrol systems. All DSMs now include Modbus over TCP/IP
capability and require only the DSM Modbus Exporter software
to configure all the DSM inputs and define the Modbus
interface. The DSM requires the Modbus Serial to Ethernet
Bridge for RS232/485 Modbus communication. See theaccessory section of this datasheet for the Modbus Exporter
