Subscribe to the required data using the subscribe service.

Request:
{
"code":"request",
"cid":4711,
"adr":"/timer[1]/counter/datachanged/subscribe",
"data":{
"callback":"ws:///myTopic",
"datatosend":[
"/iolinkmaster/port[2]/iolinkdevice/productname",
"/iolinkmaster/port[2]/iolinkdevice/pdin",
"/processdatamaster/temperature"]}
}
If the notifications are to be transmitted via the existing WebSocket connection, but without a special
data sink, the callback parameter is not required.
