Note
Other configuration variants as of FW version V3.0 of the CPU 1518HF-4 PN
As of FW version V3.0, the HF system supports additional functions and configuration
variants:
• System redundancy R1
• HF CPUs do not have to be part of a PROFINET ring or MRP domain.
This makes additional topology variants possible, such as line topology, combined
topology, or setup without additional devices.
