How to use node-red to read real time data from Siemens IOT2050 and store it in the CSV file with time stamp, is there any function code being suggested?

Hello @GAOJY11 and welcome to the forum.

How much have you already achieved -  
Have you managed to get data from the IOT2050 into Node-red?  
Have you discovered and experimented with the Write File node?  
Have you clearly defined the structure of the "CSV file with time stamp"?

1.Managed to get the data from the IOT2050 into Node-red.  
2. I haven't tried it out but I try to work on the csv instead of the write file node.  
3. still working on it

Please show us an example of the data as it comes in to Node-red (use a Debug node) and the CSV file you want to create from it.

I am sure someone will be able to help you get from the input to CSV.
