Data exchange on the PROFIBUS
Control System
Example of a slave with
PROFIBUS FieldBusPlug
* The quantities of bytes/words are defined by the connected device.
** Block parameters are transferred during power-up.
The PDP22 (PROFIBUS DP-V1) allows to suppress the block parameter transfer (executed e.g.
during power-up) setting the appropriate parameter. This parameter is not sent to the device and
cannot be set via the device.
In the Control Builder AC500 used for the CPU AC500, the parameter is 'Ignore Block Parameters' or
'Use Block Parameters' respectively in the PDP22 parameter part.

Commands and monitoring signals
The transfer of commands and monitoring signals is the essential task of the field bus and the connected
units. They control and inform mainly about the process, e.g. start a motor and inform if it runs correctly,
and are the same for DP-V0 and DP-V1.
Command and monitoring telegrams represent the cyclic data transfer.
