I have 13 panels (all EA7) on two separate lines and on separate data networks.

Several of these screens do the occasion Black/White screen crash. No permanent fix has been found

First line:

I was nearly finished gathering this data when I considered that Hardware and BootLoader could be of some importance.

If it is, please reply to this thread.

I will also check to verify dedicated power supplies on each panel.

One thing to note: On StaC11 - StaC15, If the screensaver is active when I request a screen change, the screen blinks ON and then back off.

I send multiple requests and usually the screen comes on and stays on. ??

(I need to double-check the OSDate/Runtime and SystemScreen info above.)

If it is important, I can get the pertinent info on the PAC cpu's in the lines.

I do not remember the details, but I did find an issue at one time where the "start screensaver " appeared to overlay a screensaver on top of a screensaver. In other words, if the screen had been inactive for long enough to have the screensaver triggered 3 times, then I would have to tap the screen 3 times to get the screensaver to release the screen. This project was using the PLC to turn the screensaver on.

Interesting, but I am letting the cmore timeout feature do this for me, maybe it is timing out multiple times.... Maybe this is causing the panel to crash.

I am trying to WAKE the screen.

I let it sleep until either a touch or a request from the master PAC. When the operator scans a barcode tag below the screen (in preparation to an automated setup) the screen should wake and GOTOSCRN should call the correct screen. It does wake, but the sleeps again. So, the multiple WAKE (GOTOSCRN) requests.

The wireless barcode scanner is connected to the RJ12 Serial port of the MASTER PAC. The master's task is to coordinate all DATA from the 5 stations to a DATAWORX install. So Master tells the stations ' PAC to tell the screen to wake.

Sorry If I led you to think that I was putting it to sleep.

My panel with issues also included item(s) that were outside the view-able area.

(I use a text entry object with a USB bar-code scanner as an input and leave it outside the viewing area for aesthetics).

Only time I experienced the white screen when I was using the 120v adapter to power the panel. I since then do not use them. I power up from a separate 24v power supply, other then want I use for the rest of the machine. I have not had any issues. I think they may have fixed that problem, but I still use a separate power supply for my HMI. Actually I only use the separate power supply if I am going to have lots of relays or a contactor. I know, cost more but it has been working for me.

Interesting, I installed those EA_AC pods because of AD tech recommendation to try to stop the black/white screens.

Historically, I have NOT installed dedicated power supplies (until AD tech recommendation for this issue) except in cases with contactors/relays, etc.
