UDP stands for User Datagram Protocol. UDP allows arbitrary messages to be encapsulated within a data packet and sent to any computer in the world that is connected to the Internet, whose address is known, and which is running suitable software that can make sense of it. What this means is that UDP allows a SPLat fitted with a SitePlayer to initiate a data transfer. Web pages, by comparison, must be “pulled”, i.e. a remote computer can only receive a web page by asking for it. UDP messages can be “pushed”, i.e. sent without any prompting. That makes them more suitable for “reporting by exception” such as you would use for alarms or emergencies.

It is important to note the “running suitable software” condition in the above paragraph. To put together a UDP based system you will need to have suitable software in the destination computer. You will also need to generate the appropriate UDP messages in the SitePlayer (please refer to the SitePlayer software manual).

The SPLat TSP instruction set supports UDP with an instruction called TSPSendUV.
