Device Types

The type/instance model is the foundation of Consystence. A device type is a reusable template that defines everything needed to monitor and control a class of equipment — tags, UI, alarms, commands, and AI context. A device instance is that template deployed to a real piece of equipment at a site.

If you've used Rockwell AOIs, Ignition UDTs, or NuGet packages, the mental model is similar: author once, deploy everywhere, version and update independently.

In this section

  • Type System — the type/instance/library/marketplace hierarchy, file formats, and the full equipment scope.
  • Creating Types — walk through building a device type from manifest to faceplate.
  • Tag Schema — data types, access levels, units, ranges, tag mappings, and the resolution chain.
  • Alarms & Commands — alarm definitions, command definitions, and worked examples.
  • Marketplace — browse, install, publish, and version device types.
