AC500 PROFINET in bus topology

A ring structure in AC500 PROFINET is only allowed with the usage of special 3rd party switches supporting ring structure.

According to requirements, topologies can be combined and mixed.

An easy controller-device-system consists of a controller CM579-PNIO and a certain quantity of CI50x-PNIO (if necessary expanded with S500 expansion modules). A typical constellation is described in the part “PROFINET configuration example”.
