DIGIVEX Motion - PROFIBUS 1. PROFIBUS-DP GENERAL DEFINITIONS 1.1 Definition PROFIBUS (PROcess FIeld BUS) is an international open field bus standard. It is defined by international standards EN 50170 and/or IEC 61158, and has a wide range of applications in manufacturing and industrial process automation.
DIGIVEX Motion - PROFIBUS A line bus structure is used to connect up all the devices. It is possible to interconnect up to 32 subscribers (masters or slaves) in one segment. The bus is terminated at the beginning and the end of each segment by an active terminal. Voltage must always be applied to both bus terminals for the bus to work correctly.

DIGIVEX Motion - PROFIBUS 2. COMMUNICATING WITH DIGIVEX Motion Technical specifications Connection to the PROFIBUS bus is carried out using a 9-pin Sub-D plug in compliance with the PROFIBUS standard. All RS485 interface connections are protected against short-circuiting and have galvanic insulation. The PROFIBUS interface supports transmission speeds of between 9.6 kbauds and 12 MBauds.
DIGIVEX Motion - PROFIBUS 2.1 Cyclical data transmission DIGIVEX Motion is controlled through the cyclical PROFIBUS-DP channel. Moreover, this same channel can be used for exchanging parameters. The structure of useful data for the cyclical channel is defined in the PROFIDrive Profile version 2.0, and is called PPO (Parameter Process Data Object).

DIGIVEX Motion - PROFIBUS • The complete request must be sent in one telegram; telegrams cannot be split. The same applies to the responses. • As regards response telegrams containing parameter values, the drive will always reply giving the actual value in the event that the response telegrams are repeated. •...
DIGIVEX Motion - PROFIBUS 2.6 DPV1-Profidrive V3.0 mechanism for processing parameters This mechanism is supported by the range S7-400 which has the latest firmware as well as the PME, Parvex Motion Explorer, tool through the PROFIBUS PC interfaces. It has the advantage of reducing the cycle time since the PKW cyclical exchange is no longer required to occasionally access the parameters.
