10.3 PROFINET IO PKW Header
The PKW header is used to communicate with the LaserSpeed Pro internal database. The PKW re-
quest/response bytes appear in the first 8 bytes of PROFINET I/O data. The meaning of the PKW header
bytes is the same for requests (from the master) and responses (from the gauge).
The PKW header is used to get or set gauge settings, calibration information, or specific internal measure-
ment data values.
The PKW header is exactly 8 bytes, and appears before the I/O data. The PKW header format is the same
for the output data (requests from the master) and input data (responses from the gauge). All values are in
little-endian format.
