Johnson Controls FX-DIS Local Controller Display

Local Controller Display Configuration

FX-PC controllers with a local display, or controllers with the remote stand-alone

display, are configured with CCT. The CCT provides a Configure Display menu

option that allows you to:

• define which points appear on the display pages (Input/Output View,

Parameter/Setpoint View, and Idle View) and in which order

• define which points are read-only (cannot be commanded using the display)

• specify point names and descriptions

• set display attributes including contrast and backlight intensity

• select timeout settings

• select authorization, including password definition

These options are available in CCT through the Configure Display option found in

the Tools menu while in Configuration mode. 

Local Controller Display Operation Overview

The Local Controller Display uses a fixed set of display pages to organize the

objects and data defined in the controller. Use the keypad to log on to the device

and navigate between and within each page. See Local Controller Display Keypad

for navigation information. You cannot change the order of the pages, but you can

change the contents of the pages when you configure the display with CCT.

Description of Local Controller Display

The pages that you access from the display’s Main Menu share a common layout

and theme. For example, all pages have a page title and a scroll bar used to

navigate the page. In addition, all pages support four lines of text.

If a text field shown on the Local Controller Display exceeds 20 characters, the

text scrolls across the screen once and then remains left justified with trailing

ellipses to indicate the entire text is not showing. For example, Floor1 Zone

Temperature may be shortened as Floor1 Zone Temper…. Text characters not

supported by any available character are displayed as asterisks.

Text is also shortened if the data field for the object exceeds the total allocated

width. For example, if the value of an object is 12345.67. the displayed value may

be shortened to 12345 (depending on its initial length).

Pages on the Local Controller Display:

• share a common method of row selection

• use a common method of entering data within an editable field

• show a scroll bar to indicate the scrolling feature is enabled

• support scrolling of rows and data that span multiple screens

• share a common method of wrapping row selection when the endpoints of the

rows in a list have been reached

• update their values every 5 seconds (Present Value and Reliability attributes) or

120 seconds (all other attributes)
