Connection to an ML1100 by ethernet - and it says ‘CONNECTED’. However, in the quick client and in add tag under the designer, when I click on the object for this device, it pauses, but no data files show up.
In the log, I get:
[ML1100] Browse Request request failed due to TIMEOUT
I have a packet sniffer running, here is an example of the network traffic. We have the three-way TCP handshake to port 44818, then the ENIP Req and Rsp packets. That’s it. If I go to browse, it repeats the Req/Rsp and then that’s it. I also see some keep-alives, but I didn’t feel it necessary to display those.
