[FONT="]Installed a Panelview + a few months ago. [/FONT][FONT="][FONT="]Used to replace a PV standard that worked for years but was failing.
[/FONT][/FONT][FONT="]This is on a mature DH+ network that has been running fine for several years. App is running version 7.0 of studio and talking to approx 100 tags over 4 SLC5/04s using the 2711-RN6.
After install, everything seemed good but after about a month of operation, we've started to get the communications failing entirely on the PV+ (everything else is fine.)
It's strange, it seems to happen only after a few days of operation.
At some point, the PV+ no longer appears on the DH+ network (check at RSL[FONT="]inx on PC) [/FONT]and all animations go to error on the HMI, even though the comm LED on PV+ is s[FONT="]till [/FONT]green.
When this occurs, we can fix it by cycling power to PV+ and everything comes back - back on DH+ network, animations working, etc.
[/FONT][FONT="][FONT="]After a few days o[FONT="]f running the [/FONT]same cycle repeats.
[/FONT]
From a PC I check [/FONT][FONT="][FONT="][FONT="]DH+ status counters[/FONT][/FONT] counters on RSLinx. No errors.[/FONT]
[FONT="]I think my network is sound (albeit somewhat loaded [FONT="]- ~ [FONT="]half do[FONT="]zen SLC5/04s[FONT="], [FONT="]a DHRIO, a PV[FONT="]std, another PV+[/FONT][/FONT][/FONT][/FONT][/FONT][/FONT]).
I'm hesitant to chase down optimizing the DH+ network issues since that location worked with [FONT="]PV std [/FONT]and still works for a few days after power up. Haven't changed any cabling[FONT="][FONT="].[/FONT]
[/FONT]But wondering if there is some buffering on PV+ module that locks up after so many missed comms and then needs a power down to flush?
[/FONT][FONT="][FONT="]Any ideas or suggestions?
