Hey All,
We have been having some EN2T modules (all same, up to date, firmware) experience communication drops. Odd thing is that RSLinx and HMIs stop communicating, but Producer-Consumer comms, ping, and Web Interface all still work.
We have a set of cells that this has happened to multiple times, and other sets of cells that have not experienced this at all. All have the same EN2T modules and firmware. The switches are also all configured correctly and do not show any errors.
I went into the web interface and noticed that the TCP connections were at their max (128) and then looked into the encapsulation sessions and noticed that each of the 5 HMIs had about 15-20 identical entries, which filled up the connections to its max.
A hard reset of the EN2T (pull out and reseat) corrects the problem and my TCP connections are back down to normal levels (25).
Any idea if the multiple entries for the HMIs is a cause or result of the problem? If it's the cause, any idea how it happens? Any ideas are appreciated.
Thanks!
