Highest PROFIBUS address (HSA)
Outputs the highest PROFIBUS address of an active device. PROFIBUS addresses greater
than HSA are permitted for passive devices, but only up to 126.
Profile
Depending on the connected device types and the protocols used, different profiles are
available on the PROFIBUS. The profiles differ with respect to their setting options and
calculation of the bus parameters.
The PROFIBUS subnet will only work properly if the bus parameters of all devices have the
same values.
