Figure 5-78: Control pushbuttons (standard front panel)
Control pushbuttons are not typically used for critical operations and are not protected by the control password. However,
by supervising their output operands, the user can dynamically enable or disable control pushbuttons for security reasons.
Each control pushbutton asserts its own FlexLogic operand. Each operand need to be configured appropriately to perform
the required function. Each operand remains asserted as long as the pushbutton is pressed and resets when the
pushbutton is released. A dropout delay of 100 ms is incorporated to ensure fast pushbutton manipulation is recognized
by various features that can use control pushbuttons as inputs.
An event is logged in the event record (as per user setting) when a control pushbutton is pressed. No event is logged when
the pushbutton is released. The front panel keys (including control keys) cannot be operated simultaneously—a given key
must be released before the next one can be pressed.
