I want to implement a device driver protocol to feed data into the Ignition gateway.
I studied the following articles:
Managed Tag Provider
Shows how to implement a Managed Tag Provider, to allow easy control of Ignition tags from an external program or data.
OPC UA Device
Creates an example device in the Gateway. The device will create tags that are visible under the local OPC-UA server.
But I could not find clear differences between ManagedTagProvider and StandardTagProvider!
ManagedTagProvider is the "easy" route. Implementing a standard tag provider is not documented and significantly more difficult.
Has this changed at all with the introduction of 8.3.x?
No, what are you trying to build?
We’re trying to use java to create a standard tag provider that we can then install our tags into when we first install the module. At the moment we have to create the DB connection and then create the tag provider and everything else is automated - we’re now trying to take out the “create the tag provider” manually bit.
