e!****pit -Wago app socket library - UDP broadcast

[eibe]

Hi.

Does anyone know how to use the Wago APP socket lilbrary functions for UDP broadcast?
I have tried to use the fbUdpPacketClient function to broadcast data, but it does not transmit.
Do I have to open a socket / connection first with another fb?

Any example or explanation of the functions in this library would be greatly appreciated.

UDP is an unconnected socket then you do not need to open a connection previously, the packet is sent directly to the desired IP and port.

All subnets have a broadcast IP address and it's the last (the one with all unmasked bits set to 1), if your subnet is for example 192.168.1.0 with 255.255.255.0 mask to broadcast a packet send it to 192.168.1.255

Hope it will help.
