MWM’s new RAM for gas generator sets

29 September 2022

Caterpillar Energy Solutions announced that its new MWM RAM (Remote Asset Monitoring) online status monitoring system is now available for MWM gas generator sets with the TPEM (Total Plant & Energy Management) digital power plant control. MWM RAM is suitable for all gas types and gas applications.


MWM gas generator sets are delivered ready for MWM RAM activation while existing plants can be upgraded with a retrofit kit, the company said.

Secure digital monitoring of CHP plant operation in real time around the clock from any location is possible with the MWM online status monitoring system. MWM RAM also enables the generation of reports with the output, operating hours, as well as the current and historical performance.

All plant parameters, such as the engine and generator data as well as information about plant peripherals, can be displayed and up to 1000 parameters can be logged and displayed. The user interface provides access to the data collected over a period of 13 months, enabling the operator to conduct detailed analyses.

“The combination of MWM RAM with the digital power plant control TPEM enables our customers to improve the operation of their plants,” said Uwe Sternstein, head of Service & Spare Parts at Caterpillar Energy Solutions. “Using this solution, they can optimize the maintenance and servicing of the gas generator set, even remotely.”

To gain access to all benefits, all that needs to be done is to activate RAM online. No additional installation work, hardware, or complex wiring is required.

The system incorporates multilayer security mechanisms to enhance protection against unauthorized access. Regular online updates make sure the entire system is secure and up to date, the company said.

Connectivity options include the existing TPEM Ethernet connection or a cellular connection. In this way, several gas generator sets or the entire fleet can easily be remotely supported and monitored.

MWM gas generator sets are delivered RAM-ready, equipped with TPEM CC (Control Cabinet) factory fit. By default, the TPEM CC is equipped with the needed PLE telematics device. As it is fully integrated in the TPEM control cabinet, no further wiring is required. The TPEM Ethernet connection is used for the communication with the RAM servers or a cellular module is available as an option. The easy online activation of RAM eliminates the need for work on site and additional traveling.

Existing TPEM control cabinets can be upgraded with a retrofit kit, which are suitable for all existing TPEM control cabinets and contain all required cabling and terminals.
