I have a customer system running a PR1 with a local I/O rack. Periodiacally, Groov View will losely lose connection to the I/O tags in groov view. When this happens I am no longer able to open the local I/O drop-down in the tag tree.
The I/O rack is configured in pac Control as local loopback and is the only I/O rack for this controller. The I/O rack shows good communication to the strategy when I open it in debug mode. This has happened a few times, a few months apart, with no obvious cause. The I/O rack will still be communicating to the controller, and any strategy tags in Groov View will still be connected, it’s only the Groov View local I/O tags that disconnect. So far the only way to make it restore is to restart the controller. I noticed the firmware on the controller is 3.5.1 and will be updating to 3.6.0 in hopes this will fix the issue.
When its disconnected, whats the yellow triangle show when you click on it?
Whats the local I/O show for device health, both now (when its Ok) and when its disconnected?.
Are you using ‘localhost’ or 127.0.0.1?
Have you tested connecting some groov View tags to the strategy and some to the local I/O?
When it disconnects next and after you have got the information, try just restarting groov View via its groov Manage menu rather than restarting the whole controller. If that works or not is a good data point.
When it next happens, view and grab the groov View logs.
I will have to respond to this more fully if it happens again. For now,
2.device health shows an average scan of 14ms with a max of 65ms
3.“localhost”
4.groov View tags connected to strategy work fine, while local I/O does not
Just to be clear, on point 4… Connect some tags to the I/O in the strategy. I understand there is a subtle difference between strategy tags and the I/O point tag names.
Hence trying both I/O tag names and the local I/O device.
