10 Communication
10.1 Communication interfaces
F6 / S6 devices offer the following communication interfaces.
▪ A serial diagnostic interface for the connection with diagnostic tools (e.g.
COMBIVIS) or an F6 operator.
▪ One CANopen fieldbus interface
▪ One real-time Ethernet interface
Depending on the control board, EtherCAT (control type P), EtherCAT or VARAN (control
type K) or EtherCAT, PROFINET, POWERLINK and EtherNet / IP are available on the
real-time Ethernet interface (control type A).
The diagnostic interface is always available parallel to the fieldbus interface. It can be
changed between CAN interface and real-time Ethernet interface.
Parallel operation of CAN and real-time Ethernet interface is not possible.
➢ The different versions of the real-time Ethernet interface
in control type K are based on different hardware.
Therefore the selection of the real-time Ethernet proto-
col must be observed when ordering.
