Attribute Semantics
Enabled Instances
The enable/disable state of the 32 instances, is available bit-wise from a
DWORD, where at a bit level.
Disabled instances return error 0x08 (Service Not supported) when disabled
instances are addressed with common services.
When 1, attribute 23 sets tacho source.
17 Get V Data Source SINT The Module Control Object, attributes
73, 80, 87, and 94, sets the data source
for FFT bands.
Fixed at 0
