1.1.1. Explanations about PROFIBUS-DP

PROFIBUS-DP is the variant for sensors/actors, when a higher

process response is required. PROFIBUS-DP connects the central

automation devices, like for example programmable logic controllers,

via a fast serial connection using decentral input and output devices,

sensors and actors such as controllers.

The main task of the PROFIBUS-DP system is the fast cyclic data

exchange between the central automation device (master) and the

peripherial devices (slaves); see figure "standard structure".

The explanation of the PROFIBUS-DP functions of the Lenze

controller can be obtained from the paragraph "Operating mode

PROFIBUS-DP" (page 35).
