Enable
A bit-wise enable for the Normal CM Data.
Waveform averaging is only a valid selection if or when the Normal CM data
source is set to the Alternate path and that is configured for synchronous
sample generation. Refer also to the Channel Set up Object.
The Normal CM Data enable affects not only the data available via this object,
but the data available to the Trend, Alarm and Transient Data objects:
Normal CM Data enable control, enables the type of dynamic data available to
the downstream Objects In the downstream storage objects, dynamic data
storage can be disabled per channel
(Trend/Data Manager) or by SU/CD (Transient) Normal (Live) Data is still
available if dynamic data storage is disabled in the Trend/Data Manager (and
Trans i e nt )
Source Selection
The Normal CM data can be taken before any filtering (1), from the alternate
path (4) or from a choice of two locations (2, 3) on the main signal processing
path.
Measurement Units
Actual selection of Measurement engineering units are a subset of the master
engineering units list. It is based on active measurement application for the
applicable measurement channel (related to sensor type and signal processing).

Index Description
0x01 (1) Pre-Filter - Before application-specific filters
0x02 (2) Mid-Filter - Selected mid Filter identifies inclusion of application Low Pass Filter
0x03 (3) Post-Filter - Selected post Filter identifies inclusion of both application Low and High
Pass Filter including potentially enabled integration stage.
0x04 (4) Alternate path - A CM, alternate processing, path available when so configured in the
Channel Set Up Object
