hello dear friends.

...

In the machine cpu 317 2pn/dp and hmi tp1200 and 6 profinet festo valve

have been used on profinet network. i took backup from the plc and

nodes could be seen in "accessible nodes" but there isn't any profinet

device in hardware configuration. why?

best regards.

Split first question to Backup of HMI over switch.

Hello,

can it be that you haven't install the PROFINET GSDML Files for the Festo valves in HWConfig?

Regards
