Platforms

The framework is hosted on a wide range of platforms, from small embedded controllers to high-end servers.

JACE controllers

The simplest configuration consists of a single JACE (host) controller.

This dedicated host platform provides integrated control, supervision, and network management services for a network of building monitoring and control devices.

Multiple host controllers may be combined in a distributed network that includes a Supervisor PC (laptop or desktop) to provide a variety of control and reporting functions.

Controllers host a station and a daemon process, but not Workbench. They typically run QNX as their operating system.

Supervisor

A computer, workstation or server-class machine connected to the network is called a Supervisor. This device is a network PC that acts as a server for multiple controllers. A station runs in the Supervisor computer. The daemon and Workbench may also run in the Supervisor computer.

A Supervisor running Workbench has the tools to:

  • Provision (install and update) software modules on multi-controller systems
  • Integrate support for standard RDBMS (MS SQL, Oracle, Mysql, Hsql, etc.)
  • Serve as a platform for enterprise applications
  • Provide central database storage for the attached controllers
  • Serve as an archive destination / repository for log and alarm data
  • Serve as a central server (a single IP address) for delivering graphics and aggregated data
