Rittal CMC monitoring solution

Rittal's monitoring solution, CMC, is now available in version 3 and is suitable for use in control cabinets and enclosures. The major innovation is an integrated OPC (open packaging convention) server, that is compatible with around 99% of the most widely used control console systems.

Also new, is the change to serially connected sensors with CAN buses. The CMC 3 enclosure has also been redesigned to take up less space in the server rack.

It differs from the full version in its smaller number of sensors or CAN-bus connection units and it is not equipped with a SD card slot or a USB port for flash memory sticks.

The company has redesigned its intelligent computer multicontrol (CMC) monitoring system, presenting the third-generation of the system. While the predecessors used the common IT network protocol SNMP, an OPC server, standard in control console technology, is now integrated in the CMC 3.

The system not only checks important data on temperature, humidity and voltage in the enclosure, it also provides opportunities for saving energy.

The two most important functions, the temperature sensor for monitoring enclosure climate control and an infrared sensor, which determine whether the enclosure door is open or closed, are already integrated in the central processing unit as standard.

There are also two digital inputs and one relay output present for small individual monitoring. Furthermore, the system can automatically control the enclosure light and climate control.

Other functions include a bus for measuring energy use. Monitoring humidity, air flow, pressure difference or voltage can also be integrated.

One further innovation is the change to CAN (controller area network) buses. These are integrated in the central processing unit and in the company's intelligent sensors.
