New series bridges gap to control networks
September 1st 2004

Rockwell Automation introduces the Entek XM series of intelligent measurement modules, designed to increase uptime and reduce maintenance costs through machinery monitoring and protection.

The XM series is a range of intelligent measurement, relay and communications modules that collect real-time condition monitoring data and can be mounted locally on key parts of rotating machinery. XM series modules may be applied as a standalone system or integrated with existing plant information and control systems via standard industrial networks without using proprietary instrument racks, back-planes or networks.

XM modules reduce installation time and cost because they use the DeviceNet open control network architecture, that reduces the complexity of the wiring scheme. As a result, the XM series makes continuous machinery monitoring and protection systems more cost effective to install and maintain and bring these advantages to a much wider range of applications.

XM modules can be distributed around the plant, meaning they can be located close to the machinery with no need for special cabinets or power supplies. A single network cable is then all that is needed to connect them.

Using a standard DeviceNet scanner card, the controller continuously scans the XM modules for data, alarm and relay status. Message prioritisation ensures that changes to alarm or relay status is immediately sent to the network controller.

The modules can be quickly configured to handle analogue inputs from a variety of sensors. Inputs accepted include eddy current probe, standard integrated piezo electric (EPE) accelerometer or any voltage output measurement device such as velocity or pressure transducers.

The modular design means the series is scalable, and it can grow to cover additional machines.
