Hello,
First time siemens user here. How do I connect to my new S7-300 plc for the first time via ethernet?
Right now I have a setup:
|Computer|<------->|Switch|<------->|CPU 315-2PN/DP|
I have no idea where to get started. The only thing I've tried is setting an IP address from NetPro in the PN-IO properties and it did not work.
edit: I just found where to edit the ethernet node based on the mac address (Simatic Manager -> PLC Menu -> Edit Ethernet Node. My problem now is that I can't browse for a MAC address. It gives me the error: "A network problem has occurred. Please check the networking of the network adapter you selected as the online interface and repeat the action." I'm not sure where you set this. My PC does have 2 network adapters installed, so maybe this is why the problem is occurring.
edit 2: I just figured out that I had to add my desktop computer to the hardware netpro config. I was able to successfully change the IP address of the controller. However, I am unable to make a download. I get (13:4337) "Unable to establish a connection to the module CPU315-2 PN/DP(1) (R0/S2) in the station SIMATIC 300 station.
Also, I have just pulled the CPU from the rest of my IO so that I can sit it on my desk. Obviously, I wont be able to use any IO, but will this be a problem? I just want to download to it and set up my comms to my HMI.
Thanks!
