PAN ID

Personal Area Network ID. The wireless Personal Area Network ID (PAN ID) is a unique identifier that differentiates one ZFR, or ZFR Pro, wireless network from another.

PFP Panel

Post Fire Purge Panel. A custom-built panel that provides the facility manager the ability to control the building's mechanical system after the smoke or fire event.

PICS

Protocol Implementation Conformance Statement. A document that, along with BIBBs, describes the BACnet services and objects supported by a device on a BACnet network. A PICS/BIBBs document is an ASHRAE requirement to show BACnet protocol compatibility.

Point-to-Point Protocol (PPP)

A protocol for communication between two computers using a serial interface. Typically, a personal computer connected by phone line to a server uses PPP. For example, your Internet service provider may provide you with a PPP connection so that the provider’s server can respond to your requests, pass them on to the Internet, and forward your requested Internet responses back to you. PPP uses IP and is designed to handle other protocols.

Portal

A web portal that is a specially designed website that brings information from diverse sources into one central location. Often, each information source has a dedicated area on the page for displaying information. In many portals, you can customize the contains of their portal page from the available elements.

Potential Problem Areas

The Potential Problem Areas widget provides a single display showing all items in alarm, warning, overridden, out of service, and offline statuses within a space. This display lets you filter and view data that is important to you. From Release 11.0, you can also use this widget to investigate and manage faults that occur on your site, if faults are licensed. You can use the Potential Problem Areas widget as a daily punch list to manage buildings more efficiently.

Preferences

Use these settings to configure how the Site Management Portal UI or Metasys UI behaves, including the sounds and colors, the startup views, alarm priorities, and the presence of links to external applications accessible from within the UI. The Metasys system provides customized preferences for the Site Management Portal UI and Metasys UI. Preferences are divided into two categories: system preferences and user preferences. System preferences apply to all users who log on to the site or device and affect the performance and operation of the system. User preferences apply to a specific user and define how information is displayed in the UI. User preferences do not affect the operation of the system. In Metasys UI, you configure system preferences through Site Settings and user preferences through My Profile.

Proxy Server

A server that sits between a client application, for example, a Web browser, and a real server. A proxy server improves performance by filtering requests. The proxy server fulfills the requests that it is able to fulfill and other requests are forwarded to the real server. A proxy server may fulfill a request by serving the page or other resource from a cache. It may filter or alter content and can act as a firewall. If users access the Site Management Portal UI through a proxy server, they must have the proper proxy settings configured for the Java platform.

PVT

Performance Verification Tool. The PVT is a tool for Johnson Controls users only. The tool scans the Metasys System to determine overall health, retrieve inventory lists of all controls hardware, and identifies what equipment is controlled.
