The data that is sent with an Advanced CM data request is divided into two
separate sections, the class section, and four instance sections. This process is
similar to how EtherNet/IP classes are constructed with one class instance and
multiple 'instance' instances.
The host sends the following Advanced CM Data Request Parameters as part
of an 0x4B service request.

Data Description
Type
USINT -
USINT Seconds to have ownership of Advanced CM setup.
UINT Set to 0, unless restarting an existing (unexpired) request, where
you' d pass in the Advanced Session Instance from the previous
response.
UINT Used to request synchronized data from multiples modules.
WORD Used to align data to a 32 bit boundary.
SINT Identical control to the control used in the Normal CM Data
Object (0x30A).
SINT Defines the number of samples in the Advanced CM, waveform.
SINT Identical control to the control used in the Normal CM Data
Object (0x30A), but with additional indices. See
page 481.
SINT Identical control to the control used in the Normal CM Data
Object (0x30A).
SINT Allows line/bin values to be returned scaled as Peak, Peak to
Peak, or RMS [0 Peak, 1 Peak to Peak, 2 RMS].
INT Used to align data to a 32 bit boundary.
BYTE A bit-wise enable control.

Object (0x30A).
