Experiencing problem with PR1 and Groov View with random freezing.
System overview - PR1/Groov View/Touch Screen Monitor
Problem:
System will be running fine for while then lock-in. I/O units will remain active resulting in product overload.
System restart - majority of the time the restart will reset everything and the system will run again for a while, other occasions all will startup but when booting the the menu in Groov View the touch screen will not allow input. Repeated restart, occasionally two or three times the system will work.
Also issues like these are often best handled by support where they can get the right logs and engineers on the job… But yeah, knowing what version firmware you are running is the critical start with this one.
Busy setting up remote access today to the controller, currently stand-alone 1150km away from me. Then we can involve support.
I am on a path to isolate a possible cause and will have feedback from the site this afternoon.
Problem occurred twice yesterday, made a slight change and they managed to produce the whole day. Busy monitoring today then we could possibly guide and focus on a specific area.
Once done I will log a support ticket and engage on that platform.
Hi, when this happened was the PR1 touch screen frozen or it responded to touch? (I know you said it got frozen sometimes after reset, but exactly when this happened?) Was it visible on the network or responded to pings?
Hi Beno, would like to continue this thread with support team. To confirm, if I want to bring this under the eye of support , do I simply send suppot@opto22.com a email
Yes, that’s the right thing to do.
Drop them an email (you have it correct) and they will assign a ticket number and work the issue till its resolved.
Thanks for the insight, this one is still a new install, 4 trends,aprox 10 points. Started its hanging shortly after install. Will develop this through support channel and update once resolved.
Some useful general advice when running external touchscreens with EPIC, is when the customer is complaining that the groov-EPIC appears to be “frozen” and not responding to commands, it is well worth checking USB touchscreen cabling and connectors and even pull the HDMI cable and USB cables out of the PR1 to force it to revert to using its own integrated touchscreen. If it works, then the problem is not actually the fault of the groov-EPIC
Also worth checking if any of your application software has wrongly configured the USB port and is using the same as the connection to the external touchscreen. First one to connect gets control of the port.
Once we figured out that the USB touchscreen controller on the external monitor was the source of the problem and on another occasion a 4 port USB hub in the middle had managed to lock itself up, as no touchscreen commands were being received from the external touchscreen monitor.
Probably not the case in this incident, but well worth eliminating suspects when these things occur.
The problem is that the touch-screen I am using starts up at the same time as the Epic. After a minimal amount of time it sees no input on the HDMI and goes into sleep mode (no setup in touch-screen to deactivate this function).
By the time the Epic reaches the stage it is ready, and try’s to initialize the display and USB (around the 2min20 mark) it fails to correctly achieve this as a result of the touch-screen having a nap.
No configuration problems or cabling concerns.
The work-around that has been successfully deployed at this stage is wiring the touch-screen supply through a relay which is activated by the Epic using a startup chart. So, when the epic is ready, it switches on the touch screen and keeps it on as required.
