CHAPTER 5: SETTINGS PRODUCT SETUP
The local and remote operation of each user-programmable pushbutton can be inhibited through the
PUSHBTN 1 LOCAL
and settings. If local inhibit is applied, the pushbutton ignores set and reset commands executed
PUSHBTN 1 REMOTE
through the front panel pushbuttons. If remote inhibit is applied, the pushbutton ignores set and reset commands
executed through FlexLogic operands.
The inhibit functions are not applied to the autoreset feature. The inhibit function can be used in SBO control operations to
prevent user-programmable pushbutton activation and ensuring "one-at-a-time" select operation.
The inhibit functions can also be used to prevent pushbutton activation from the accidental pressing of the front panel
pushbuttons. The separate inhibit of the local and remote operation simplifies the implementation of local/remote control
supervision.
Pushbutton states can be logged by the event recorder. User-defined messages can also be associated with each
pushbutton and displayed on standard and enhanced front panels when the user-programmable pushbutton is activated,
and when in the latched mode when the user-programmable pushbutton is deactivated. With the graphical front panel
interface, instead of messages, the status of user-programmable pushbuttons can display on a single-line diagram and
can also display in annunciator page windows and in actual values page cells.
For the graphical front panel, the pushbuttons 1 to 8 are linked to the eight physical pushbuttons, and pushbuttons 9 to 16
are mapped to the graphical interface pushbuttons. To set the buttons for pushbuttons 9 to 16, access Settings > Product
Setup > Graphical Panel > Single Line Diagram Editor, click the PB symbol in the toolbox, then configure pushbuttons 9 to
16.
— This setting selects the mode of the pushbutton (Self-Reset, Latched, Disabled). If set to
PUSHBUTTON 1 FUNCTION
"Disabled," the pushbutton is not active and the corresponding FlexLogic operands (both "On" and "Off") are de-asserted. If
set to "Latched," the pushbutton remains on until reset.
— This setting specifies the top 20-character line of the user-programmable pushbutton message and is
PUSHBTN 1 ID TEXT
intended to provide ID information of the pushbutton. See the User-definable Displays section in this chapter for
5
instructions on how to enter alphanumeric characters from the keypad. On a graphical front panel, this setting instead
controls the label of the user-programmable pushbutton component on single-line diagrams.
— This setting specifies the bottom 20-character line of the user-programmable pushbutton message
PUSHBTN 1 ON TEXT
and is displayed when the pushbutton is in the "on" position. For example, the text displays in the Event Record. See the
User-definable Displays section for instructions on entering alphanumeric characters from the keypad. On a graphical
front panel, this setting instead controls the on status text of the user-programmable pushbutton component on single-
line diagrams. This setting is not applied to the physical pushbuttons on the graphical front panel.
— This setting specifies the bottom 20-character line of the user-programmable pushbutton message
PUSHBTN 1 OFF TEXT
and displays when the pushbutton is deactivated and the is "Latched." A message does not
PUSHBUTTON 1 FUNCTION
display when the is "Self-reset" as the pushbutton operand status is implied to be "Off" upon its
PUSHBUTTON 1 FUNCTION
release. The length of the "Off" message is configured with the
PRODUCT SETUP  DISPLAY PROPERTIES  FLASH MESSAGE
setting. On a graphical front panel, this setting instead controls the off status text of the user-programmable
TIME
pushbutton component on single-line diagrams. This setting is not applied to the physical pushbuttons on the graphical
front panel.
— This setting specifies the time required for a front panel pushbutton to be pressed before it is deemed
PUSHBTN 1 HOLD
active. This timer is reset upon release of the pushbutton. Note that user-programmable pushbutton operation requires the
front panel pushbutton to be pressed a minimum of 50 ms. This minimum time is required prior to activating the user-
programmable pushbutton hold timer.
— This setting assigns the FlexLogic operand serving to activate the user-programmable pushbutton
PUSHBTN 1 SET
element. The duration of the incoming set signal must be at least 50 ms.
— This setting assigns the FlexLogic operand serving to deactivate the user-programmable pushbutton
PUSHBTN 1 RESET
element. This setting is applicable only if the user-programmable pushbutton is in "Latched" mode.
— This setting enables the user-programmable pushbutton autoreset feature. This setting is applicable
PUSHBTN 1 AUTORST
only if the pushbutton is in "Latched" mode.
— This setting specifies the time delay for automatic reset of the pushbutton when in "Latched"
PUSHBTN 1 AUTORST DELAY
mode.
— This setting assigns the FlexLogic operand serving to inhibit user-programmable pushbutton
PUSHBTN 1 REMOTE
operation from the operand assigned to the or settings.
