In order to meet the client’s requirements, we set up hub-and-spoke architecture. The hub houses all screens and non-transferable artifacts and the spokes house local tags and a set of screens to use for local redundancy. From a hub-based client, users are able to view any site to any level of granularity. If the connection to the hub is disrupted, the spokes still have access to their local screens and data. The GAN (gateway area network) allows Ignition to use remote tag providers which allow for such decentralization of tags, while also allowing all the sites to be centralized to one area. Alarm state is passed through the GAN for dissemination by the central server.
Ignition has allowed the client to upgrade its SCADA system without upgrading the legacy hardware. The flexibility and intelligent scripting driving our data collection for the client’s accounting system has mitigated both connectivity issues and the frequency of collected errors, drastically reducing the requirement for human intervention. Our communications metrics provide actionable information on underperforming devices which in turn allows the administrators to target devices for reconfiguration or replacement. The metrics can also provide valuable comparisons of the effectiveness of configuration changes to the communication network. Kymera standardized the data and display of the assets and together with the GAN architecture the client is now able to visualize the entire system from one client.
