Integral interfaces:

• Ethernet
  The integral Ethernet interfaces (10/100/1000 Mbit/s) can be used for IT communication and for data exchange with PLCs such as SIMATIC S7 (with "SOFTNET S7" software packages).
• PROFIBUS
  The isolated PROFIBUS interface (12 Mbit/s) can be used for connecting distributed field devices or for connecting to SIMATIC S7 (with "SOFTNET for PROFIBUS" software package).
• PROFINET
  The three (IRT-enabled) PROFINET ports can be used to connect distributed I/O, SIMATIC S7 and drives. The switching-enabled ports of the CP1616-compatible PROFINET option support linear bus and tree topologies (WinAC RTX from Version 2008). Alternatively, the interface can be used as a standard Windows interface.
• Further interfaces
  For connecting additional I/O devices, 2 free slots for PCI or PCIe modules, 5 USB 3.0 (Universal Serial Bus) interfaces, and one serial interface are available.
