We have been having problems with one of our panelview plus 7 – 1000 hmi screens. When pressing the GO TO screen button the system will continue showing the current screen for a few seconds before switching to the new screen. The problem is pretty consistent when switching to any screen. The HMI is from 2015 using a runtime v7.0 program. The freezes/hang ups are not critical but a significant annoyance.
I’m wondering if this is more likely a panelview hardware issue, a networking issue, or something else?
If I get an opportunity when the line is down I plan to swap out panelviews with a spare to see if the issue follows to help narrow it down. Reserving line time for an annoyance issue is difficult.
If I do narrow it down to a panelview issue is there anything that can be tried before buying a new hmi?
Some additional details:
- When I launch a copy of the hmi and run it on my laptop the screen changes respond instantly which leads me to think it is not a network problem.
-We have the same program and theoretically the same networking on nine lines in the facility. Only one line is giving us problems.
-Each screen shows the system time taken from the panelview system/time variable. This number typically counts up each second but every 30 seconds or so will stall and jump ahead 3 seconds. These stalls are independent of the screen change delays.
-Each screen also shows the machine phase 0-360 read from the plc. This number updates consistently even when the hmi hangs up.
-It seems that if the button to change the screen is pressed multiple times rapidly the screen takes longer to update. For example pressing once changes the screen in three seconds. Rapidly clicking the button can make it take 8-10 seconds. It acts like if you were hitting refresh constantly on a slow loading website.
