I'm fairly new to the PLC world. We are adding a pc to a line at my work the pc is to track good/bad parts and up/down time of the machine maybe late keep track of alarms. The pc will only be receiving data not sending any data to the PLC . Do I have to add the pc to the hardware configuration? Or is there another way to send the data to the pc from the PLC? The PLC is a s300 programmed is step7 5.6. And will be hooked up to the PLC with Ethernet.
