Hi, I have been doing quite a bit of research on ethernet/IP and believe my idea will work but I'd like to get some second opinions. We have about 30 powerflex 70 drives with 20-Comm-er cards in them all Daisy chained creating a linear network. The first drive is connected to an unmanaged switch which has 4 additional drives connected to it separately. The switch is connected directly to the enbt card in our chassis. The last drive in my linear network is not connected to anything expect the drive before it. Everything works A-Okay until we need to turn one drive off. Everything downstream loses communications and the whole machine stops. I know this and try to use the local motor disconnect but somehow some of the older guys in our plant can't seem to get this.
So, doing research, I have come up with an idea.
-gettinf a 1783-ETAP and connecting the first drive to port 1 and the last drive to port 2 and then plugging port 3 into my unmanaged Ethernet switch. I will set the ETAP as the ring supervisor. I believe my ring will work but will it work how I want it by going through a switch?
Also, do the 20-Comm-er cards automatically detect a ring network or is there configuring that needs to be done?
I'm attaching some pictures of this clusterfu*k we've got going on. The 30 drives in a row is what I'm wanting to convert to ring. And the other larger drives are the others connecting to unmanaged Ethernet switch. And the chassis is where they are communicating to.
Any help would be appreciated!
Thanks!
