hello
i am using S7 300 PLC, i am unable to figure out how to send data to the plc through rs232 cable i'll be glad if you can help me with this.
in my plc there is one port used for downloading the program. i am wondering if i can use the same serial port to communicater with the plc while it is running the program (to pass parameters to it)
