Communication
10.3 Communication via PROFINET IO
Example
The following diagram shows a configuration example of a drive with three 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:
1. Using parameter p8929 = 2, define that data from two control systems should be received
2. Using parameters p9601.3 = p9801.3 = 1, enable PROFIsafe for axes 1 and 2.
3. Configure the PROFINET communication in HW Config (see Section "Configuring the

via the PROFINET interface.
controllers").
When the system boots, using p8929 = 2, the drive system identifies that PROFINET
telegrams are expected from two control systems, and establishes the communication
corresponding to the configuration in HW Config.
