Ethernet The two integrated Gigabit Ethernet interfaces (10/100/1000 Mbit/s) can be used for IT communication and for data exchange with programmable controllers such as SIMATIC S7 (with the "SOFTNET S7" software package).
PROFIBUS The optional floating PROFIBUS interface (12 Mbit/s) can be used to connect distributed field devices or to interface to the SIMATIC S7 (with the "SOFTNET for PROFIBUS" software packages).
PROFINET The optional PROFINET interface can be used for connecting distributed field devices or for controlling drives.
