I am using a cpu319f-3 pn/dp plc..For some unknown reason I have lost P1R and P2R. I cannot ping the plc or browse the node. I have tried the cable, that didnt help. I have the dc5v light green and stop flashing. I there any way possible to reset the plc to default status to get these back. I am also running threw a scalance x224. I can see the scalance and the hmi but not the plc to set the ip address. I cant get the mac to come up..
