Hi everyone,
I’d like to confirm my understanding of how Ignition Edge Data Sync (Tag History) behaves after a network outage.
Mu Scenario is:
- Edge collects event-based data (one message per event).
- Tag History and Data Sync are enabled.
- During a connection loss, Edge buffers data locally.
- When the connection is restored, historical values are sent to the Standard Gateway with original timestamps.
On the Standard Gateway:
- A Tag Change Script listens to the synced tag.
- The script parses each incoming value and writes one row per event to a database.
** My question is:** Can you confirm that each replayed historical value will still trigger the Tag Change Script normally, allowing all buffered events to be processed and stored correctly, assuming the script uses event.timestamp and does not rely on real-time logic?
Thanks!
