Communication via PROFINET
You can either communicate via Ethernet using the inverter, or integrate the inverter in a
PROFINET network.
● The inverter as an Ethernet station (Page 371)
● PROFINET IO operation (Page 87)
In PROFINET IO operation, the inverter supports the following functions:
– RT
– IRT
The inverter transmits the clock synchronism but does not support clock synchronism.
– MRP
Media redundancy, impulsed with 200 ms
Requirement: Ring topology
– MRPD
Media redundancy, impulse-free
Requirement: IRT and the ring topology created in the control
– Diagnostic alarm
in accordance with the fault classes specified in the PROFIdrive profile. See Activating
diagnostics via the control (Page 90).
– Device replacement without removable medium
Requirement: Topology created in the control
– Shared device
only in the case of control units with fail-safe functions (see Safety function manual)
