8.6 Reading the Process and Diagnostic Data
You have the option to read the process and diagnostic data for the LioN-
P modules using the integrated web server. The web server provides the
data in standardized JSON format. The data is accessed via the website. The
relevant address is:
http://[IP address]/data.jsn
In higher programming languages, the process and diagnostic data is read via
HTTP requests. The following example uses the GET command in an HTTP
request to obtain the data:
HTTP request:
GET /data.jsn HTTP/1.1
HTTP response:
HTTP/1.1 200 OK
Server: servX
Content-Length: 73
