Good morning all
I am a student at the University
I am working in a project that requires communication between arduino with ENC28J60 via ethernet, a switch and a seimens s7-1200 plc.
i programmed my arduino to send data to plc without problem i read the data in the plc everything is fine but i don't know how to do the reverse (send data from plc to arduino). if anyone can help me please that would be great
Thanks
Start by checking the S7 manuai about how to select and send data. Check what type of output the S7 serial is as well as baudrate
