u Send subscribe/unsubscribe requests with "callback” parameter ("ws:///myTopic").
w ifm IoT-Core sends notifications about existing WebSocket connections to the myTopic topic.
Example: Using WebSockets
Task: The current values of the following parameters are to be sent regularly to the myTopic data sink
via an existing WebSocket connection:
• Product name of the IO-Link device at IO-Link port 2
• Cyclic IO-Link input data of the IO-Link device at IO-Link port 2
• Operating temperature of the IO-Link master.
Solution: 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.
