17.2 Operation Mode in PROFIBUS:
HRVS-DN supports both DPV0 and DPV1.
DPV0 (Cyclic) allows:
o Start and shutdown.
o Read parameters (write parameters are not allowed via DPV0).
DPV1 allows:
o Everything that DPV0 allows
o Change the cyclic parameters that display via DPV0.
o Write to registers.
17.3 Description of the DPV0 (Cyclic) Frame:
From the Profibus controller to the HRVS-DN two bytes (16 bits) are transferred.
From the HRVS-DN to the controller 40 bytes are transferred.
