Integral interfaces:

• 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 for coupling to the SIMATIC S7 (with the "SOFTNET for PROFIBUS" software package).
• PROFINET
  The PROFINET interface can be used for connecting distributed field devices or for controlling drives.
• Further interfaces
  For connecting additional I/O devices, up to three free slots are available for PCI-104 modules (with expansion frames), as well as 4 high-speed USB interfaces and two serial interfaces
