Controlling the Web-IO with TCP/UDP Sockets
So that under UDP a message can be automatically received
when states change, the Web-IO provides a variety of various
alarm conditions.
i
A detailed description of how to use these alarm
possibilities can be found in the
Alarms section
Include a header
The Web-IO can if needed precede the sent string with a header
containing the IP address and the name.
To enable a header, go to Config >> Basic Settings >> HTTP and
select GET Header enable . Clicking on Logout and Save
activates sending of the header.
Example:
. The IP address of the Web-IO is 172.16.232.17.
. „W&T Web-IO 12xDigital“ was entered as the device name
under
Config >> Device >> Text „“.
. GET /input?PW=& was used by the application to poll the
inputs.
The Web-IO returns:
172.16.232.6;W&T Web-IO 12xDigital;input;0000
If GET Header enable was activated, the header precedes all data
sent by the Web-IO.
