Hi Guys,
I have had this working at one point and I have no clue what has changed that has stopped my step 7 from being able to connect via Ethernet/Profinet whatever you want to call it, to a CPU 315 2pn/dp processor. I have tried creating a NAT and a bridge from VMware 12.5 to my windows 7 ultimate VM with Siemens step 7 5.5 SP4 installed and every time I go to accessible nodes I get nothing. I have verified it is not the PLC as I have connected a PG laptop to it that we have on hand and it has no problems seeing the PLC. The other thing I do not understand is I can ping the IP address of the PLC but when I open step 7 and hit accessible nodes nothing comes up. I am pretty sure that this protocol uses MAC addresses to communicate but does anyone have a better detailed explanation of exactly how it works?
Also I have tried every configuration I can think of. I set a IP address on the host machine that had a subnet that could communicate to the PLC then NAT that into the VM. Tried Bridging the connection with setting a IP address on the same subnet as the PLC on both the host and VM. Tried just setting the IP address in the VM and just setting the IP address on the host using DHCP other wise. Nothing seems to work. I also turned off all other adapters (wireless card) as this is on a Laptop, that did not work either.
If anyone has detailed pics/configs of the host LAN adapter, the VM LAN adapter, the PG/PC interface, and the settings for the adapter in the VM I would greatly appreciate it
Been at this issue for about a half a day and it worked at one point months ago connecting to a similar CPU.
Thanks,
PG
