CMU module

The CMU module is displayed below a CMU node in the plant tree. Allocation of sensors creates the link between the plant configuration and the CMU.

Next to the module, you can see whether it is a HSp (high speed, e.g. a vibration sensor) or an LSp module (low speed, e.g. a temperature sensor). HSp modules are always plugged into the backplane bus on the CMU as this is the only place that the high sampling rates up to 40 kHz per channel are possible. The LSp modules are set to ibaNet750 Analog and ibaNet750 Digital in the CMU templates, and these modules are not enabled by default. The ibaNet750 device is an external fieldbus system, which can be connected to the CMU using fiber optics and is compatible with the WAGO 750/753 I/O system. Further information about ibaNet750 can be found on the iba website (http://www.iba-ag.com/).
