I have downloaded a library for the S7 connection to the Arduino but I don't know how to continue now. and google isn't helping much. I assume I can refer to the LOGO inputs in the arduino now but I have no idea how, anyone done something similar? thanks,

In the LOGO everything is stored in DB1. The offset is depending on the data you want to address. I attached a screenshot. For example if you want to read an input you have to address DB1 with offset between 1024 and 1031. Hope this helps! Best regards Attachment LogoVm.jpg (1165 Downloads)
