Example: Read several parameter values of the IO-Link master simultaneously
33840
Task:
The following current values are to be read by the IO-Link master: temperature, serial number
Solution:
Read the current parameter values using the getdatamulti service (data point temperature:
/processdatamaster/temperature; data point serial number: /deviceinfo/serialnumber)
Request object:
{
"code":"request",
"cid":4711,
"adr":"/getdatamulti",
"data":{"datatosend":["/processdatamaster/temperature","/deviceinfo/serialnumber"]
}
}
Return object:
{
"cid":4711,
"data":{"processdatamaster/temperature":{"code":200,"data":44},
"deviceinfo/serialnumber":{"code":200,"data":"000174210147"}},
"code":200
}
