Hey guys
I just need to get things clear in my head
If I have a remote ignition gateway and a central cloud based ignition gateway which are connected via VPN in a ‘Hub and Spoke’ config. Connection is via cellular, so not the quickest.
I want to be able to run the same project that is on the remote gateway on the cloud gateway to provide a method of remote monitoring and control.
- Should I connect directly to the remote AB plc via the cloud gateways opc ua using the same tag setup that is on the remote gateway
- Or is it better to add the remote gateways opc to the cloud gateway and browse the device using the same tag structure setup as the remote project.
- As per 2 but expose the remote gateways tag provider to the cloud and drag the tags over to become cloud tags.
Just wondering really what is the most efficient method to minimise the Load on the remote plc. Or is each method above going to have the same result?
Cheers for any guidance
