Four operation modes of class I master station and four work states of the slave station in Profibus-DP field bus control system were presented.Taking the DP system as the object to design the MS0communication program
and the design procedure of the master station
slave station and interrupt program were given.Three working stages of DP system from start to entering normal data exchange were summarized.Test results and message analysis verified this communication program's correctness.
