Hello,
I've recently installed wireshark on my DA server (Wonderware). I have a network will alot of micrologix PLC's. Since installing wireshark I can see that the micrologix are constantly sending out gratuitous ARPs. I did a little research on this and it sounds like gratuitous ARP's should only happen on startup of the PLC. But it looks like the micrologix is routinely sending them out. Does anyone know anything about this?
