Example
To clear event records using pushbutton 1, set Settings > Product Setup > Clear Relay Records > Clear Event Records to
FlexLogic operand PUSHBUTTON 1 ON. Then program the pushbutton by setting Settings > Product Setup > User-
Programmable Pushbuttons > Pushbutton 1 Function to "Self-reset."
The figures show user-configurable pushbuttons for the front panels.

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.
