Appendix A CIP Objects
Dynamix AC
Measurement Object
The AC Measurement Object (class code 0x390) defines configuration of an
AC overall measurement by selecting source, smoothing constants, and
definition of measurement units. Two instances are linked to each available
transducer channel.
The second instance in each case relates to a secondary overall measurement
(B) with another source, measurement units, and potentially different
detection method to the primary overall. Example, primary: mm/s RMS,
secondary: g peak. Currently, other instance attributes are common to the pair
of instances/measurements. However, work to support the setting of
independent time constants for overall (0) and overall (1) ('A and B') is
ongoing.
The gSE application supports only one overall measurement per
channel, Overall (0).
The Dynamic pressure application is FFT band focused/optimized so
does not support either of the overall measurements.
gSE Mode In gSE mode:
Use the HP filter setting as required (typically 100, 200, 500, 1000, 2000, or 5000 Hz
but not restricted to these values)
Use the LP filter setting to indicate the required FFT FMAX (typically 25, 100, 200, 300,
or 1000 Hz but again not limited to these values)
Based on the preceding information, the module automatically implements suitable
decimation - the configured decimation is ignored.
The settings for gSE results in the filters being unusually set (HP > LP) - this setting is
normal for gSE measurements.
Aeroderivative mode When an Aeroderivativemode has been selected, the roll off the LP and HP filters are
automatically increased from the standard -24 dB to the -60 dB required for that
application.
