4. Once all of the settings on the screen have been entered, press the Edit pushbutton a second
time and the settings will be validated. If the settings are in range, the screen will flash
CHANGES SAVED, and the Edit LED will go out. If you want to abort the edit session without
changing any settings, 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.
Performing Control Operations
Control operations can be executed from the LCD HMI from menu branch 2, CONTROL. These functions
allow you to control the state of virtual switches, override logic and control the active setting group, and
override the logic and control the state of output contacts. All of these functions work similarly to the
process of entering settings in that you press the Edit pushbutton, use the UP and DOWN scroll
pushbuttons to select the desired state and press the Edit pushbutton for the action to be executed.
Figure 10-11 shows virtual switch 243 as an example of a virtual
switch screen. See Section 4, Protection and Control, for more
details on the x43 and 101 functions. Table 10-4 describes each
of the callouts shown on Figure 10-11. The user programmable
label for this switch has been set to DIFF_CUTOFF. The TRUE
(closed) state label has been set to NORMAL and the FALSE
(open) state label has been set to 87_OFF. The logical mode for
this application would be set to Mode 2 (On/Off switch).
Table 10-4. Virtual Control Switches Controls and Indicators
Locator Description
A
User selectable label (meaningful name) for specific virtual switches. Switch 243
identification label set to DIFF_CUTOFF.
B
User selectable label for the closed (1) state for Virtual Switch 243. Switch 243 closed
state label set to NORMAL.
C
User selectable label for the open (0) state for Virtual Switch 243. Switch 243 open state
label set to 87_OFF.
D
Icon to show the current switch position (status). In Figure 10-11, the current status is the
closed state, which is labeled NORMAL.
E
Current switch status. This indicator should correspond to the current user labeled switch
status. The switch is closed (1) and the user label for closed is NORMAL.
To operate the switch, you would use the following procedure:
1. Using the manual scrolling pushbuttons, scroll to Screen 2.1.x, \CTRL\43\. Alternatively, if the
screen has been placed in the automatic scroll list, simply wait for it to appear and press the
RIGHT or LEFT scroll pushbutton to freeze the display.
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. See the following paragraphs,
Entering Passwords, for details on entering passwords from the HMI. Once access has been
gained to the control function, the Edit LED will be lighted and a cursor will appear in the action
field.
3. Press the UP or DOWN scrolling key to select the desired action. The selections available are
dependent upon the logic mode setting for that switch. If it is set to Mode 1, the action choices are
pulse or one of the two positions as defined by the user programmable state labels. If the mode is
set to Mode 2 (ON/OFF Switch), the choices for action are limited to one of the two positions. If
the mode is set to Mode 3 (OFF/Momentary ON Switch), the choice for action is limited to pulse.
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 edit
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.
