actual Profibus bit rate is
automatically set by the
Profibus master and can
be up to 12 Mbit/s.)

1) In continuous mode the size depends of the biggest configured data offset
of a data item to be send to the master. In request mode the size is 8 bytes.
2) In continuous mode the size depends of the biggest configured data offset
of a data to be read from the master. In request mode the size is 8 bytes.
3) When configuring the Profibus master system, the lengths of these
buffers are needed. The device calculates the lengths according the Profibus
data and profile configuration and the values define the in/out module to be
configured for the Profibus master.
4) If the value is "", Profibus protocol has not been selected or the device
has not restarted after protocol change or there is a communication problem
between the main CPU and the Profibus ASIC.
