Automatic baud rate recognition
The Profibus DP address is set via the display of the device.
For an optimum adaptation to the process control system, the process representation input (feedback
signals) can be configured as desired.
Profibus DP according to IEC 61158 and IEC 61784
Line (fieldbus) structure. When using repeaters, tree structures can also be implemented. Coupling and
uncoupling of devices during operation without affecting other devices is possible.
