Wide-area SCADA Architecture |
As described in the Remote Datalogging section, the network-centric nature of Ignition makes it easy to access data across a wide area network. Additional key features such as retargeting make it possible to blend complete systems hosted at different locations into one seamless architecture.
Each location operates independently, but when combined with a secure inter-location network (such as a VPN over the internet), any location can securely interact with the other locations. There are many possible layers of security, included encrypted communication and the ability to adjust authentication access for each location. For example, users from remote sites may be allowed to only view data, and not modify or control machinery. Conversely, if desired, a central operator may be allowed to control aspects of each location. |
