Gateway Crash When Browsing Siemens Symbolic PLC

Ignition 8.3 Early Access
1

Hi all,

We have a Siemens S7-1500 communicating using the new driver.
There are a handfull of tags communicating successfully with the driver.
When we browse the device to add a tag from scratch (I.e. Add tags popup, hit refresh so no folders are open), during drill down of the folders, the whole gateway crashes.

Looking at the logs:

I have the hs_err_pid5260.log but am unsure the best way to share it.

The error is quite repeatable, so can provide any additional information /logging as required! :slight_smile:
Its always the frame [AGLink40_x64.dll+0x235982] when it crashes.

This may be vaguely related to [null, Bad_NotConnected(“Communication with the data source is defined, but not established...] as we're also having this issue, however with it crashing the gateway I didn't want to hijack the thread :smile:

Thanks!
Alex

Thanks for reaching out!

You can share any relevant logs to this Dropbox link, maybe in a zip named similar to your forum user name, so that I can more easily keep things apart.

Some logs that might be helpful are the siemens related loggers in the gateway, but they'll need to be set to Debug to catch anything useful.

Any info about the specific of the folder (and its contents) you were trying to drill into would also be very helpful. It sounds likely that there is an issue when trying to browse a specific node in the problematic folder. If you can share what it looks like on the PLC, that would be useful.

Thanks very much!
I've uploaded what I can, and included a few notes to try and help :blush:

Thanks Alex! I suspect this will be enough for me to reproduce the issue. I'll reach back out once I have anything.
