For the controller that is intended to send data to ibaPDA, you have to set up a UDP communication. The destination address is the IP address of the ibaPDA server. You have to declare the destination port within the defined port range in ibaPDA (see General interface settings).

The default destination port range defined in ibaPDA is 5010 – 5017. The maximum supported length of the UDP data is 4096 bytes. ibaPDA rejects longer messages.

The controller should cyclically send a message with a fixed layout to the ibaPDA system using a fixed destination port. If more than one message with a different content is needed, the same destination IP address must be used, but to another destination port within the defined range.

Each UDP connection is uniquely identified on the ibaPDA side by the "Destination port number" and "Source IP address". This means that one controller can send several messages to the same ibaPDA even using a destination port already used by other controllers.
