Sending Datasets from Ignition Edge to remote Ignition Server

Ignition
1

Hey all,
We've been designing a system using Ignition Edge to update to a remote server.

Currently, we use several dataset memory tags on an Ignition to store information such as orders and other values. If we set this to store in our historian the dataset is not stored properly, to get this to work we configured several named SQL queries to store these in specific tables in our DB on a normal Ignition.

We are now switching to Ignition Edge, that then sync's the data in a single Ignition. With Edge we won't be able to use named queries and as the historian won't save them properly, how can we ensure these are transmitted properly. The edge will have lots of tags, so we'd ideally like to not configure them as remote tag providers and use named queries on them.

Would MQTT transmission be the only course of action?

You can use system.util.sendRequest() to have the remote system do the work. Depending on the scope required, you may need Edge's compute plug-in.

Oh, that looks useful, would be easy to move the dataset into a dictionary and send that, then use a message handler to write to a dataset/named query into our database.

Thanks!
