149744 Trendmaster Dynamic Scanning Module (DSM) Datasheet Bently Nevada Machinery Condition Monitoring Description The 149744 Trendmaster Dynamic Scanning Module (DSM) is a compact 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 card or reserved. The TIM input card connects to Bently Nevada TIM and proTIM modules. 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 efficient features 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 the required 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 and automation systems without the need for additional hardware. This capability provides a low-cost entry-level alternative to System 1 that uses the basic trending and alarming functionality that is integral to existing process control 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 the accessory section of this datasheet for the Modbus Exporter software and Serial to Ethernet Bridge part
