5.1 Data management
The controllere consists of different units:
This manual exclusively describes the following subject:
•
The optional
fieldbus interface
Profibus DP operates independently and exchanges data with the
central system via a "Dual port RAM" interface .
For the AS-i controllers with Profibus interface the data management of Profibus DP is handled in the
operating system (firmware) of the device. A special driver in the PLC user program in the controllere
is not required. In the mode Run/Stop the digital and analogue output data is not transferred to the
outputs of the AS-i slaves. Therefore this data must be recopied in the PLC user program of the
controllere.
