Communication
10.3 Communication via PROFINET IO
Example
The following diagram shows a configuration example of a drive with 3 axes. The A-CPU
sends standard telegram 105 for axis 1 and standard telegram 102 for axis 2. The F-CPU
sends PROFIsafe telegram 30 for axis 1 and axis 3.

Configuration
To configure the connection, proceed as follows:
● Using parameter p8929 = 2, define that data from 2 control systems should be received
● Using parameters p9601.3 = p9801.3 = 1, enable PROFIsafe for axes 1 and 2.
● Configure the PROFINET communication in HW Config (see Section "Configuring the
● When the system boots, using p8929 = 2, the drive system identifies that PROFINET
Note
When booting, the drive system first requires the configuration data of A-CPU and then
establishes a cyclic communication to this CPU taking into account the PROFIsafe telegrams
expected.
As soon as the drive system has received the configuration data of the F-CPU, then cyclic
communication is also established here and PROFIsafe telegrams are taken into
consideration.

controls").
telegrams are expected from 2 control systems, and establishes the communication
corresponding to the configuration in HW Config.
