Figure 5-56: User-programmable pushbuttons (graphical front panel)
Front panel pushbuttons and LEDs can be custom labelled as outlined in the Front Panel Labelling section in the previous
chapter.
Each pushbutton asserts its own “On” and “Off” FlexLogic operands (for example,
PUSHBUTTON 1 ON
and
PUSHBUTTON 1 OFF
).
These operands are available for each pushbutton and are used to program specific actions. If any pushbutton is active,
the
ANY PB ON
operand is asserted.
Each pushbutton has an associated LED indicator. By default, this indicator displays the present status of the
corresponding pushbutton (on or off). However, each LED indicator can be assigned to any FlexLogic operand through the
PUSHBTN 1 LED CTL
setting.
The activation and deactivation of user-programmable pushbuttons depends on whether latched or self-reset mode is
programmed.
•
Latched mode
— In latched mode, a pushbutton can be set (activated) by asserting the operand assigned to the
PUSHBTN 1 SET
setting, by directly pressing the associated front panel pushbutton, or with the graphical front panel
interface. The state of each pushbutton is stored in non-volatile memory and maintained through a loss of control
power.
The pushbutton is reset (deactivated) in latched mode by asserting the operand assigned to the
PUSHBTN 1 RESET
setting, by directly pressing the active front panel pushbutton, or with the graphical front panel interface.
It can also be programmed to reset automatically through the
PUSHBTN 1 AUTORST
and
PUSHBTN 1 AUTORST DELAY
settings. These settings enable the autoreset timer and specify the associated time delay. The autoreset timer can be
used in select-before-operate (SBO) breaker control applications, where the command type (close/open) or breaker
location (feeder number) must be selected prior to command execution. The selection must reset automatically if
control is not executed within a specified time period.
•
Self-reset mode
— In self-reset mode, a user-programmable pushbutton can be set (activated) by asserting the
operand assigned to the
PUSHBTN 1 SET
setting, by pressing the front panel pushbutton, or by the graphical front panel
interface. A pushbutton remains active for the time it is pressed physically or pressed in the graphical front panel
interface, plus the dropout time specified in the
PUSHBTN 1 DROP-OUT TIME
setting. If the pushbutton is activated via
FlexLogic, the pulse duration is specified by the
PUSHBTN 1 DROP-OUT TIME
only. The time the operand assigned to the
PUSHBTN 1 SET
setting remains On has no effect on the pulse duration.
The pulse duration of the remote set or local front panel pushbutton must be at least 50 ms to operate the
pushbutton. This allows the user-programmable pushbuttons to properly operate during power cycling events and
various system disturbances that can cause transient assertion of the operating signals.
