Power Chart not showing loss of connection to Remote Tag Provider

Hi everyone,

I’m currently troubleshooting a behavior in a distributed Ignition architecture and want to see if there’s a way for handling the powerchart when a data source goes offline.

The Setup:

Central Gateway: Full Ignition install hosting the main Perspective project.
Field : Ignition Edge nodes handling local OPC acquisition and acting as Remote Tag Providers (RTP) to the Central Gateway.
Historian: Data is being logged via the Edge nodes.

The Problem: When the Gateway Network connection between the Central Gateway and an Edge node drops, the Power Chart on the Central Gateway continues to display the last received value. The trend essentially "freezes".

From an operator's perspective, there is no clear visual indication that the data is stale/absent. A flat line for a temperature or pressure sensor could be misinterpreted as a stable process when, in reality, the data source is simply unavailable.

Any insights on how to prevent this would be greatly helpful.

Ignition Platform	v`8.1.47`

Ignition Edge Platform	v`8.1.48`

You should note what version of Ignition (Full & Edge) you are using.
