Nova’s visualization system allows you to create HTML5-based pages to display your process status. Integration with Software Toolbox’s Symbol Factory provides Nova with a rich set of scalable SVG symbols, all of which can be recolored according to your process data. The rich editor operates entirely within your web browser, and pages can even be edited from the device manager. Tabular primitives allow the display of multiple tags with just a few clicks, and can even take a JSON array or object and construct a table based on its contents. This last feature allows a PLC UDT or the results of a SQL query to be displayed with a single primitive.
Nova’s pages can be displayed either on a kiosk-mode browser on the device on which the platform is executing, or on any other web browser connecting to the device. Each connection has its own user interface context, so switching to another page locally will not impact remote users. By constructing disjoint sets of pages and links, different users can be given access to distinct data, or to distinct views of the process. Data from other sources such as webcams or the on-board Grafana server can be embedded within pages, as can documents such as PDF instruction manuals. And because Nova’s uses HTML5 and vector graphics, the display page automatically scale to fit the target device, allowing that design once, view anywhere experience.
