Rittal adds CANbus connectivity to its Computer Multi Control monitoring system

05 October 2011

Rittal has introduced CMC III, the third and completely re-designed generation of its Computer Multi Control (CMC) monitoring systems featuring Controller Area Network (CAN) bus connectivity integrated within the central processing unit and in Rittal's intelligent sensors. The adoption of fieldbus as opposed to traditional I/O greatly simplifies wiring requirements and associated clutter.

Rittal has also taken a new direction with its environmentalsensors. Two most important functions, the temperature sensor for the cold air intake at the front of the server and an infrared sensor, which monitors whether the enclosure door is open or closed, are already integrated in the central processing unit as defaults.

Completely revised, the CMC III enclosure now requires far less expensive space in the server rack. Just one-third of a height unit is enough space for the third generation CMC's processing unit. In addition, the new power pack is housed in an identical enclosure, which is easily installed in the same height unit and connected via cable. Power supply via Power over Ethernet (PoE) is also possible.

With the CMC III, network integration, as well as configuration and commissioning, are performed comfortably with a laptop and a USB port. Users can choose between TCP/IPv4 and TCP/IPv6 as network protocols. Working with RiZone IT infrastructure management software and the Microsoft System Center Operations Manager, CMC III is capable of initiating automated counter-measures. Emergency situations can be resolved quickly without human intervention, while responsible members of staff are alerted by text message or e-mail.
