All methods for communication via UDP broadcast
Provides communication via UDP/IP in both directions.
Is derived from UdpBase.
Example
The example includes a Broadcast UDP client. If a telegram arrives at input 1 (PIN_I_DATA), it is sent via UDP. Via inputs 2 (PIN_I_IP) and 3 (PIN_I_PORT) the broadcast IP and port are determined.
