Locator Description
A
This is the screen number. It eases navigation by indicating the current branch and level
in the menu tree structure.

User selectable label (meaningful name) for specific virtual switches. The ‘Switch 143’
identification label is set to ‘RCL_DISABL’.
C
User selectable label for the closed (1) state for Virtual Switch 143. The ‘Switch 143’
closed label is set to ‘DISABLD’.
D
An arrow icon indicates the current switch position (status). In Figure 10-10, the status is
open (0), which is labeled ‘ENABLD’.

User selectable label for the open (0) state for Virtual Switch 143. The ‘Switch 143’ open
label is set to ‘ENABLED’.
To operate the switch, you would use the following procedure:
1. Use the manual scrolling pushbuttons to scroll to Screen 2.1.x (43 AUX SWITCHES). If the screen
has been placed in the automatic scroll list and it is scrolling at the time, simply wait for it to appear
and press the RIGHT or LEFT scroll pushbutton to stop the scrolling on Screen 2.1.x.
2. Press the Edit pushbutton to gain access. If password security has been initiated for control
functions, you will be prompted to enter the appropriate password. Once access is gained to the
control function, the Edit LED will light.
3. Press the UP or DOWN scrolling key to select the new state (as indicated by the arrow) for the
switch. The “P” selection will pulse the state of the switch from its present state to the opposite
state for approximately 200 milliseconds. The allowable states are dependent upon the logic mode
setting for the switch. If the switch is set to Mode 1(On/Off/Pulse), the “P” (pulse) selection will give
an “:INVALID PARAMETER” error. If set to Mode 3 (Off/Momentary On), selecting one of the two
states will give an “INVALID PARAMETER” error.
4. Press the Edit pushbutton a second time and the switch will change to the selected position, the
screen will flash CHANGES SAVED, and the Edit LED will go out. If you want to abort the editing
session without changing any controls, press the Reset pushbutton before you press the Edit
pushbutton the second time. The screen will flash CHANGES LOST and the Edit LED will go out.
Resetting Functions
The Reset pushbutton is context sensitive. Its function is dependent upon the screen that is presently
being displayed. For example, pressing the Reset key when the Demand screen is displayed will reset the
demands but it will not reset the alarms, etc. It is necessary to scroll through the menu tree to the Alarm
screen to reset an alarm. You are not prompted for a password when using the Reset key.
There are two BESTlogic™ variables associated with the HMI Reset pushbutton. Logic variable TRSTKEY
becomes TRUE when the Reset pushbutton is pressed while the Target screen is displayed. Logic
variable ARSTKEY becomes TRUE when the Reset pushbutton is pressed while the Alarm screen is
displayed. See Section 8, Application, Application Tips, for examples on the use of these variables.
