Industrial data networks requirements and industrial bus systems requirements in particular are extensive and constantly expanding. Industrial Ethernet is the established backbone technology to meet these needs. Our Industrial Ethernet capabilities provide outstanding functionality and flexibility — even over long distances — and can accommodate your changing requirements.
Communications processors allow integration of SIMATIC - also in complex systems - over Industrial Ethernet/PROFINET. With their own processors, they relieve the CPU of communications tasks and facilitate additional connections. The CP 343-1 is designed for use in SIMATIC S7-300, and the CP 443-1 is used for S7-400. The CP 343-1 Advanced and CP443-1 Advanced provide integrated network isolation between the control level (Gigabit) and the field level (Fast Ethernet or PROFINET) incl. IP routing. The CP 443-1 Advanced also enables smaller local networks to be configured thanks to the integrated 4-port switch. The CPs can communicate using different protocols, such as ISO, TCP/IP, UDP, S7 communication, and they can be used as PN IO Controller or IO Device.
