Is Excel alike dealing with sensorEDGE's aggregated IO-Link sensor data - as the real-time processing platform e.g. 'Streamsheets' is offering supporting it - possible?

Yes this is possible since the sensorEDGE solution is providing the IO-Link-sensor data on MQTT over an Internet hosted MQTT broker.

STEP 1:

For a simple test sign up for a trial playground account under https://cedalo.com/pro-streamsheets/trial-signup/ and confirm your email address.

STEP 7:

Watch the JSON coded payload of the incoming messages in the payload window to the left (update rate depends on your configured sensorEDGE data update rate)

STEP 8:

a. Draw a line chart on your sheet using the icon Image Added

b. From the payload window drag and drop any value you want to monitor to your sheet. The example shows the object "Temperature" and its value right next to it.

c. To draw a chart of a value a helper function such as TIMEAGGREGATE() is neccessary.

Use this function in any other sheet's data cell as shown below. Specify the original value of interest as source, the period and the AggregationMethod as paramters of the function. The examples shows "B2,60,1".

d. For your chart specify the sheet's data cell you want to get displayed. The example shows data cell "B3"
