The udp_receive node
This node listens on an udp socket and awaits data in a special format, which is defined
by the parser parameter, the parser will then try to convert the data to faxe format and emit the
result.
If the changed option is given, the node will only emit on changed values (crc32 checksum comparison).
The udp listener is protected against flooding with the {active, once} inet option.
Example
def parser = 'parser_robot_plc_v1'
|udp_recv()
.ip('212.14.149.8')
.port(9715)
.parser(parser)
.as('data')
