These optional assemblies allow an operator or engineer to view and, depending upon the keypad type, modify, variable values and associated status information. Variables can include inputs, process variables, calculated variables, constants, setpoints, tuning parameters and outputs used in a measurement or control application. Status bits include alarm state, alarm acknowledge, control, manual, and questionable data. ControlWave controllers support two different types of display/keypad assemblies; one with a dual-button keypad (see Figure 1-1), and one with a 25-button keypad (see Figure 1-2). Each key has positive tactile feedback. This means that as you firmly depress the keys, you will feel it click as it engages. Both display/keypad assemblies utilize identical four-line by 20 character liquid crystal (LCD) displays. Figure 1-1.- Display/Keypad Assembly – Dual-Button Keypad & 4 X 20 Character Display Issue Nov-2010 Introduction 1-1 ControlWave Micro Display/Keypad Instruction Manual (CI-CWM-DSPKEY) Figure 1-2.- Display/Keypad Assembly – 25 Button Keypad & 4 X 20 Character Display 1-2 Introduction Issue Nov-2010 ControlWave Micro Display/Keypad Instruction Manual (D5135) Chapter 2 – Installation & Configuration Caution To ensure safe use of this product, please review and follow the instructions in the following supplemental documentation: WARNING Supplement Guide - ControlWave Site Considerations for Equipment Installation, Grounding, and Wiring (S1400CW) ESDS Manual – Care and Handling of PC Boards and ESD Sensitive Components (S14006) EXPLOSION HAZARD When the ControlWave-series controller is situated in a hazardous location, turn off power before servicing or replacing the unit and before installing or removing wiring. Do not connect or disconnect equipment unless the power is switched off or the area is known to be non-hazardous. In most cases, the display/keypad assembly arrives factory-installed in the enclosure. If you purchase the display/keypad assembly separately, and want to install it yourself, follow the installation drawings. See Figure 2-1 for the dual-button keypad, and Figure 2-2 for the 25-button keypad. Once you’ve installed the display/keypad assembly, connect the display cable between the RJ-45 jack (J1) on the display/keypad assembly and the RJ-45 display interface jack on the controller. 2.1 Configuring Your Application to Work with the Display/Keypad You configure the Display/Keypad in ControlWave Designer by adding the DISPLAY function block to your project, and configuring its parameters. The amount of configuration required varies depending upon the type of keypad (25-button or dual-button) and the operating mode you choose. See the DISPLAY function block online help pages in ControlWave Designer for instructions.

The dual-button display/keypad does not support changing variable values or status information; for that, you must have the 25-button keypad. From an opening screen, you enter a list selection screen to select the list you want to view, and then the display scrolls through the variables in the list, one at a time, at a user-defined rate so you can view variable values and status information. If there is no keypad activity for a certain period of time, scrolling stops and the display shuts off to conserve power until you press any key. When you press a key after the timeout the display returns to the opening screen. Note: Your application programmer can specify the length of time before scrolling stops through the iiDisplayBlankTime parameter in the DISPLAY function block. Dual-Button The two buttons available are the down-arrow (ITEM) and right-arrow Keypad (LIST) buttons. Table 3-1 describes the function of these buttons. Figure 3-1. Dual-Button Keypad Table 3-1.

Identifier Display The first display that shows on the screen is the Identifier Display. (See Figure 4-2.) Figure 4-2. Identifier Display The Identifier Display is the starting point from which you can go to other displays. It shows an identification message and the words Login and Scroll at the bottom of the screen. The identification message varies depending upon configuration entries made in the DISPLAY function block; it might contain the name of the controller, the plant equipment it monitors, or other information. Notes: 4-2 If your display shows something else, press the [F4] key until you see the words Login and Scroll on the bottom line. If your screen is blank, turn the brightness screw clockwise. This screw is located to the left of the Keypad (looking at the rear of the 25-Button Display/Keypad Assembly, see Figure 2-2). If no letters Using the 25-button Display/Keypad Issue Nov-2010 ControlWave Micro Display/Keypad Instruction Manual (D5135) appear, the controller has not been programmed properly to operate the keypad. Legend Line The words Login and Scroll at the bottom of the screen are on the legend line. Depending upon which screen is active, the function keys (that is, key [F1] through [F4]) do different things. The legend line tells you which function keys are active and their purpose for that particular screen. Up to four legends can appear on the legend line. The legend on the far left corresponds to the current function of the [F1] key. The current assignment for the [F4] key is on the far right. The current use for keys [F2] and [F3] are described to the left and right of center. When no legend appears, that function key is not active on this screen. For example, in Figure 4-2 only [F1] and [F2] are active. Note: The application programmer can change the legends shown in this manual, so you may not always see the default legends shown. From the Identifier Display, you have two choices. Pressing [F1] allows you to log-on if you have a password. Pressing [F2] activates automatic scrolling through a list of variables. Figure 4-3. Identifier Display Legends and Corresponding Keypad Alignment for 25 Button Membrane Key Matrix Keypad System 4.1 Scrolling (25-button keypad) To begin automatic scrolling, press [F2] from the Identifier Display (Figure 4-2).
