In "DP/ MC (Equidistant)" mode, a global control telegram is sent. The global control telegram is always sent at the beginning of a cycle. The MC slave devices can synchronize with this broadcast global control telegram, which is sent at the beginning of a PROFIBUS-MC cycle. In this way it is possible to synchronize drive control loops exactly with an NC task. PROFIBUS-MC has a constant PROFIBUS cycle with only a few microseconds of jitter.
