TCP/UDP Server
General
The board provides an Ethernet port (RJ45 — connector
J7) which allows accessing all the parameters (registers) of
the module through a TCP or UDP connection.
Here you will find a small comparison table between these
two protocols (non exhaustive):
Features
UDP
TCP
CheckSum (Data integrity)
YES YES
Multiport (data multiplexing)
YES YES
Flow control
NO YES
Acknowledge Data
NO YES
Multipacket order reconstruction
NO YES
Two ports are available using the
TCP protocol
:
Port
#80
for HTTP communication.
Port
#8010
Access to the control port
Only one port is accessible through the
UDP protocol
:
Port
#8010
Access to the control port
You will find a detailed description on the different ports
in the next pages.
Note:
The board allows up to 4 simultaneous TCP connections.
That means for example: that 4 users can connect to the #80
port to see the web page, or 4 users can be connected to the
#8010 port and control the I/Os, or even that two see the page
and two control the I/Os, etc. In UDP protocol there is no
limitation on the number of users connected.
