4.1.4 HTTP - Reading diagnostics infos from device

For diagnostics and the error memory the following applies:

GET /diagnosis

Requests the status of the diagnostics memory. The Web-IO

returns:

diagnosis;0000;00000000;00000000;00000000

The 4-place value indicates the number of stored messages.

For the three 8-place hexadecimal values each set bit

represents one of the possible messages.

GET /diagnosisx

“x” specifies the index for the currently stored message. The

Web-IO returns the corresponding message text. “x” may not

be greater than the number of currently present messages.

GET /diaglistx

Returns the messages for the individual message bits (max.

64).

Deletes the message memory:

GET /diagclear

Example with Browser:

http://<IP address>/diagnosis

4.2 Polling via UDP

Open a UDP connection to the IP address of your device or to

the Net-ID as a broadcase to Port 42279 (preset, can be

changed).

Send one of the above expressions to the device and the latter

will return the measured value on the port you are using.

When using multiple devices it may be practical when

broadcasing messages to have the name and IP address

of the device included. To do this, enable „GET Header
