5.6.3 Profibus-DP, slave DSQC 352
General The unit can be operated as a slave for a Profibus-DP system.
Supply The Profibus does not need any external power feed. All the robot cells are connected to the
trunk cable through a special D-sub connector which works as a very short drop cable.
Because of this the profibus will work correctly even if a robot cell is turned off.
Technical data Also see the Profibus-DP specification, Internation Standard DIN E 19245 part 3.

Communication
concept
The Profibus-DP system is able to communicate with a number of external devices, depend-
ing on the number of process words occupied by each unit. The robot may be equipped with
one or two DSQC 352. The Profibus-DP inputs and outputs are accessible in the robot as
general inputs and outputs.
