Now there is a plan to take same values from PLC and put them into database. What options I have? As far as I know I can use Modbus or OPC. Can I use something else? Connection through profinet. And based on that do you have any recommendations of programs working on win10 to take the data from PLC and write it in database? The best would be free program. If not free it can be lifetime license (subscription is not an option).

	A rating will be well appreciated.
