TCP UDP module


I have been asked about the UDP and TCP Drivers-module. What difference there is over the Modbus module? :scratch:

There’s a huge difference. The only thing they have in common is that they happen to use TCP, just like any other ethernet driver.

The TCP/UDP module does not implement any protocol. They are meant to connect to devices like barcode scanners, which upon receiving a connection, simply stream data back over the connection as it becomes available. You setup some simple options on what size or character constitutes a message barrier and a field, and that’s it.
