The only connection you can make with this device is a slave connection on the OPB; click in the leftmost white bus square to establish this connection (a lowercase 's' will appear in the box).
The objective of the research is to design a multifunctional and universalizable slave interface for PROFIBUS DP, so an ordinary device can be connected on this bus conveniently.
In distributed measurement and control system with bus structure, master slave communication may be replaced by race communication, when real time and burst are needed.
