DX LCD Display User’s Guide 4-1 Chapter 4 Operating the DX LCD Display Introduction The DX LCD Display is operated through a simple keypad and menu system interface that provides easy, intuitive access to the data and parameters stored in the DX controller. It provides password protection for those functions that change data in the DX controller, such as adjusting/overriding point values, editing time schedules, and changing optimal start/stop parameters.
4-2 Display Terminals Key Concepts Display and Keypad The DX LCD Display includes a sealed membrane touchpad, and a 240 by 128 pixel Liquid Crystal Display (LCD) that shows up to 16 lines of text with 40 characters per line. Figure 4-1 shows the layout of the front panel of the DX LCD Display. Table 4-1 shows Display Screen Components, Table 4-2 and Table 4-3 describe the keypad.
Operating the DX LCD Display 4-3 Display Screen Certain areas of the display screen always show the same type of information during normal operation (i.e., once the DX LCD Display has selected a display configuration). These areas of the screen are indicated in Figure 4-1 and described in Table 4-1. Table 4-1: Display Screen Components Area Description Name of Display Configuration Lists the name of the current configuration.
4-4 Display Terminals Keypad Figure 4-2 shows the layout of the sealed membrane keypad: esc dxtk_9 Figure 4-2: Keypad Table 4-2 describes the keypad keys and symbols, and Table 4-3 describes the Light-Emitting Diode (LED) indicator located in the center of the keypad.

4-6 Display Terminals Home Page The DX LCD Display shows a graphical Home Page as the default screen when it is moved to a different controller. Each of the eight display configurations can have a different Home Page. The Home Pages are customizable, and can contain live point data from the DX controller. The default Home Page is shown in Figure 4-4. For more information on defining custom Home Pages, see GX-9100 Software Configuration Tool Technical Bulletin (LIT-6364060).
Operating the DX LCD Display 4-7 Point Data The DX LCD Display stores up to eight separate display configurations. Each configuration specifies up to 96 points of the DX controller that can be displayed and monitored by the DX LCD Display. The point data is shown on up to 8 pages (or screens) of 12 points per page. On power up, the display attempts to select a display configuration to match the DX controller configuration. It uses a default display configuration if it cannot find a match.
4-8 Display Terminals The override command changes the value of a point whose values are set by the controller through an automatic control process. Override the point to prevent the controller from changing its value. This can be thought of as a manual override of the automatic control process. A release command must be sent to the point to return it to automatic control (see Releasing Overridden Points in the Detailed Procedures section).
Operating the DX LCD Display 4-9 Alarm Log The Alarm Log shows the history of the last 96 alarms that have occurred in your system and the date and time of their occurrence. In addition to the alarm Change-of-State (COS), the log also shows the return-to-normal COS. This allows you to tell at a glance when alarms occurred and when they returned to their normal state. Note: The Alarm Log can only show alarms on the points included in the display configuration that are defined as alarms, i.e.
4-10 Display Terminals Time Schedules The DX controller stores eight time schedules used to schedule actions on a weekly basis. Each schedule defines up to eight time slots. Each time slot defines a start time, a stop time, and one or more weekdays. When the current day and time-of-day agree with all of the conditions of any time slot, the output of the corresponding time schedule is set to On. The DX LCD Display can be used to view and edit the schedules of the connected DX controller.
Operating the DX LCD Display 4-11 Trend Data If the connected DX controller supports Trend, it can collect and store Trend data for up to 12 analog and logic variables. An analog variable corresponds to an analog item in the DX controller, such as an analog input. A logic variable in the DX controller is a byte value representing eight digital bits, such as the eight digital inputs DI1 to DI8. Trend data is collected for all eight bits of the logic variable.
4-12 Display Terminals Viewing and Editing Analog Trend If you selected an analog trend variable in the main Trend Data screen, the Analog Trend Data screen appears, showing a graphic plot of the data available from the DX controller in Figure 4-5. GROUND FLOOR TREND 5 11:40 Green Room Temp SAMPLE: Actual 06 June 1997 13:23 23.4 Deg C 100 Auto 0 More...
Operating the DX LCD Display 4-13 The plot itself is shown as a continuous line of up to 61 points, where each point represents one sample. If any sample falls outside of the range, then that sample point will not be displayed and there will appear to be a break in the plot. The range values can be adjusted, however, to make all samples visible in the same graph. The procedure for editing the range values is described later in this chapter.
4-14 Display Terminals The Trend Group screen shows a menu with the names of the individual bits of the digital variable (i.e., logic variable byte), as defined in the display configuration. The third line of the screen shows the name of the trend variable. Note: In Figure 4-6, the number 4 in the menu means that the fourth bit was not given a name in the display configuration, so its number was used as the default name. This may mean that the bit is not used.
Operating the DX LCD Display 4-15 Procedure Overview Table 4-4: Operating the DX LCD Display To Do This Follow These Steps: Establish Communication with a DX Controller Connect the serial cable between the display and the controller. Connect the cord of the power supply adapter to the display and plug the adapter into an AC wall socket. to For direct connect, when the power-on self-test is complete, press continue.
4-16 Display Terminals Detailed Procedures Establishing Communication with a DX Controller To establish communication with a DX controller: 1. Connect the serial cable between the display and the controller. See the Installing the DX LCD Display chapter for details. 2. Connect the cord of the power supply adapter to the display and plug the adapter into an AC wall socket. See the Installing the DX LCD Display chapter for details. Note: There is no power switch on the DX LCD Display.
Operating the DX LCD Display 4-17 3. Press the key to continue when the power on self test is complete. If you do not press a key, the screen is cleared after a five second delay. The next screen that appears depends on whether you have connected the display to a different DX controller or whether it is still connected to the same controller to which it was connected the last time it had power. If it is a different controller, the Home Page for the active configuration appears.
4-18 Display Terminals If a controller’s configuration does not match one of the predefined configurations in the display unit, the default configuration is used (if enabled) for that controller. To choose and connect to a DX via the N2 Bus: 1. Use the and keys to choose the desired controller. 2. Press the key to confirm your selection. The Home Page for the selected controller appears.

Note: Some screens are sub screens of other screens, in which case pressing the esc key returns you to the parent screen. To reach the Main menu, keep pressing esc until the Main menu appears. Be careful, however, not to press esc too quickly because you might inadvertently reset the display.
4-20 Display Terminals Displaying the Home Page To display the Home Page: 1. From the Main menu, select the Home Page option. The Home Page defined in the current display configuration appears. 2.
