Port type

For any changes of input ports and relays of I/O devices a corresponding event will be generated:
13.
Finally, you can also
Modify
and
Delete
selected I/O devices via the right-click mouse menu.

16.2 Generic I/O devices
It is also possible to add other TCP/IP based systems to an Observer system as I/O devices. In order to
do that an I/O device of the
Type
"Generic TCP" has to be added as described above. The
corresponding system or device then has to be configured to send TCP messages to the Observer
server's port 10100 with the following syntax:
statechange,<DEVICE_ID>,<IO_PORT_ID>,<IO_PORT_VALUE>
So for example changing the value of the first port of an I/O device with ID=1001 to "0" would require
the following TCP message:
statechange,1001,1,0
