Visualization and Data Project

Visualization, data project, file, or “data-set” — these terms refer to the method of organizing data points to facilitate easy access. This organization allows data points to be grouped into collections, charts, and screens in any way necessary to simplify the operation of technical equipment and the evaluation of data.

Mervis offers three primary ways to display data within a project:

• Table View: A tabular display where individual data points are listed row-by-row and can be organized into groups.
• Graph View: Charts that use pre-defined templates to determine how data and lists of points are displayed, or which users can configure on-the-fly during standard operation.
• Schema View: Schematic displays consisting of pre-created graphical screens that mix live data with visual elements and embedded charts.

Creating a data project or visualization is generally straightforward if the delivery of the I&C (BMS) system follows the recommended standards.

The following core materials are required:

• Complete list of all available data points in the system:
  • This must include descriptions, locations, units, data types, possible values, and the range of values for writable points.
  • It is best practice to start with a complete overview of all points and then trim it down based on user needs, rather than trying to add points later.
• Documentation of technology or building topology:
  • For example, DWG schematics that can be used to create floor plans and system layouts.
• Data logging definitions:
  • It must be determined which part of the system handles data trending. If this is managed by the visualization, you must specify the logging period, precision (decimal places), and logging algorithms (e.g., on change, periodic).
• User list:
  • Every user should have their own login credentials so that access rights can be set appropriately and user actions can be audited.
• Alarm settings:
  • Identification of which data point values should be monitored, who should receive alarm notifications, and the required delay times for those alerts.
