[BUG-14364] Remote Vision Client displays stale tags after lose and regaining of network connectivity

We have a remote Ignition Gateway that if we lose internet connectivity to it and then regain connection, then the tags will have stale quality in the Vision Client and cause overlays on Components binded to OPC Tags even though the Gateway shows good quality with these tags.

The steps that can taken to recreate the issue are below:

1. Launch a Vision Client on a machine that is remote from the Ignition Gateway.
2. Disconnect Internet on the machine with the Vision Client in order to lose connection to the Ignition Gateway.
3. Reconnect Internet on the machine with the Vision Client.
4. Overlays for stale tag quality do not go away.

However, it does work as expected from my VM, and the Tags resume good quality after reconnecting to the Gateway. I’m not sure why it only works from my VM and never from my Base Machine, but I have logs from the client console from both the VM and my Base Machine.
After analyzing the logs, I found that there is one line that really sticks out in the client console on my VM (works) that isn’t on the one from my Base Machine (doesn’t work):

15:27:48.253 [ClientExecEngine-4] WARN tags.subscriptions - Subcription crc mismatch, will resubscribe.

I am not sure if missing that is the meat of the issue so I will paste the logs from the Client Console from both Vision Clients and the information about my base machine, my VM, and the Ignition Server.

Ignition Server Info:
OS - Microsoft Windows Server 2016 Datacenter
Ignition Version - 8.0.2 (b2019060511)
Base Machine Info:
OS - Microsoft Windows 10 Pro

Hi emcconell,

Was able to duplicate the above issue where the vision clients on the remote vision client remain stale after losing the internet connectivity and regaining it. I found the workaround was to log out of the remote client and then log in at which point the red overlay was longer be displayed. However, will write an internal ticket to track this issue.

Thanks,
Anthony

Anthony,

Thank you for creating a ticket to resolve this issue, and I look forward to hearing about the solution.

Best,
Eddie

I can’t wait either. I just discovered this today when a tech tripped the breaker on one of our industrial switches. The hmi still worked but had the red overlay after network reconnect.

Hi damean.thomas

Did you try the workaround I suggested where you log in and out of the client when you regain connectivity? hopefully you can do that in the mean time as you wait for a fix.

Yes I did. It was a bit troubling until you understand it. Is this connected to the problems in ignition 8 vision where tags go stale for a second on window changes?

Hi damean.thomas

I believe might be connected but we working hard to resolve the issue as soon as possible.
Thanks for your patience.

Anthony

This issue was fixed in the 8.0.3 Nightly build that was uploaded today (7/16).

This issue occurs for Vision clients on 8.0.14. I noticed this bug was fixed in 8.1.0 (Bug 323), but 8.1 is still a release candidate and not a stable release. Any nightly build planned to fix this bug for 8.0.16?

Logging out and logging back in fixes the issue, but that isn’t really an option for HMIs on the factory floor since it takes too much time and many TV display controls are inaccessible to personnel on the factory floor. This would require us to monitor every single client and manually log out/log in on hundreds of screens.

I too have been seeing this behavior on 8.0.15 where a client shows stale information overlay and a log in/log out / screen change will correct it.
This information is used on some non-interactive displays so the operators cannot access any controls to rectify. Is there any patch that will address this behavior?

Hi,
We have this issue using 8.0.16

We are having this issue still as well on version 8.0.14. Any updates?

We are also still having this issue on 8.0.15.
Any news on a fix for the bug or is it worth upgrading to 8.1?

Upgrade to 8.1.1. It completely resolved this issue for us as well as other stability issues. Best upgrade we’ve ever made with Ignition.
