I 'm newcomer in PLCs. I want to fetch live data from a s7-300 PLC in a windows based PC. Please suggest me what is the least cost way of doing this.
I have come to known that it is done using OPC server. OPC servers seems to be costly,can i do it without OPC server.
Someone told that it is possible using winc software,is it true?
