Hello everyone who reads this. This week I've got Weidmüller PLC for testing. This thing has got Node-RED preinstalled which I'm not familiar with, just heard a lot of times that people use this environment to do a lot of things. The goal is to use this PLC for Building management system/automation. The problem that I got right now is with the logs. Please can anyone tell me how to log files directly into PC hard drive? For example .csv file with time+temperature parameters.
PLC is connected directly trough ethernet cable to a laptop.
I've tried my first ever flow to build up a .csv log file and getting this error - "failed to append to file: Error: EACCES: permission denied, open 'C:\RED_Logs\Temperature.csv"
Please can anyone give me a bit of guidance how to solve this?
Thank you
Heres my flow:
