Hi,
In a distributed solution we have made an architecture where the main servers are running in a virtual environment. But some remote sites are connected with 4g and on these sites we have a local computer with a platform deployed with application objects, an OMI application and an OI server connected to a local PLC. This platform is part of the same galaxy and the System Management Server is the GR node.
The plan was that if the 4g connection goes down the objects and OMI application and OI server would continue to run locally and historian data would be buffered in store forward. However what we experience when the connection goes down is that OMI gets bad quality on all attributes. However, objects are having good quality on its attributes, so it seems the issue is OMI getting data via PCS from the objects.
So the question is: Is OMI reliant on connection with the GR node/System Management Server to be able to run? Is there a way to make this "island mode" work in case of lost connection. Or do we need to make a separate galaxy with a local System Management Server for it to work?
