■ The CPU has an integrated Ethernet communication processor.
■ The connection happens via an integrated 2-port switch (X3/X4).
■ Via Ethernet (default: 192.168.1.1, ‘MAC1’) you have access to:
– Programming / remote maintenance of the CPU.
– Web-based management WBM of the CPU.
– OPC UA communication of the CPU.
■ In the optionally available ‘PROFINET IO controller
’ operating mode, you can connect
your PROFINET devices here.
■ In the optionally available ‘PROFINET I-Device’ operating mode, you can connect your
CPU as I-Device to a PROFINET IO controller here.
The interface is reserved for future extensions.
