Having issues with an Edge MC data source.
The Edge MC is picking up machine status changes from an OPC server. These status tags are linked to Tulip Machine Attributes - and the attributes drive the Machine State. The Edge MC seems stable, and OPC data is flowing - however every now and again an attribute value ‘gets stuck’.
For example a machine will quite happily be reporting status changes (Running, Stopping, Stopped, Idle etc) but will then get stuck on a single status (eg Running) for a long period of time.
On investigation, the underlying OPC tag value has changed, but the Tulip attribute is stuck on an old value. If I remap the attribute to the same tag, the the attribute value refreshes and is accurate again. It is although the tag/ attribute becomes frozen/ non-responsive.
Has anyone seen this behaviour? Is there anything I need to do with the Edge MC to stop values getting stuck? I do not thing the issue lies elsewhere beyond the Edge MC (or perhaps Tulip itself) as the underlying opc tags data is changing as expected.
Any ideas welcomed.
