Application

The CPU 1518HF-4 PN is the CPU with an extremely large program and data memory for applications which have higher requirements for availability compared with standard and fail-safe CPUs.
It is suitable for both standard and safety-critical applications up to SIL3 / PLe.

The CPU can be used as PROFINET IO controller. The integrated PROFINET IO RT interface is designed as a 2-port switch, enabling a ring topology to be set up in the system. The additional integrated PROFINET interfaces with separate IP addresses can be used for network separation, for example.
