PROFINET supports protocol SNMP, very useful for the remote maintenance and the diagnosis network.
PROFINET and pyramid CIM
PROFINET allow an easy integration of very drunk ground (not only PROFIBUS), thanks to the footbridges especially designed for this purpose. PROFINET is a complete standard, which answers all the requirements relating to the implementation of Ethernet in automation. PROFINET meets needs which go from the level ground on the level led.
