The S7-1214 is wired to a Nanobeam(setup as station) and wireless bridged to another NanoBeam(setup as accesspoint) and wired to the S7-1516 and a HMI. I can ping the S7-1214 from the remote side. I can change values from the HMI in the S7-1214 on the remote side. Communication between the PLC's are setup via transfer areas and was working fine, when on the the same wired network, but with the wireless system in between, the PLC-PLC communication is not working. Can anyone tell me what is wrong?

The two ethernet devices are connected in order to symbolize the wireless connection I read that it should be possible to to use wireless lan and profinet io.

If there is any connection displayed please delete it, recompile and download the HWCN to both PLC. Wireless and PROFINET IO is possible , if you use the correct devices and Accesspoints ;) Regards Christoph

The other is that the PLC in the picture have a disturbed sign, so anything is not ok, what exactly you can see in the detail diagnostic in the detailview of the PLC. Regards Christoph
