The enable switch function block monitors the status of the enable-switch device.
The Output Enable signal is on when the inputs from the monitored enable-
switch device are active. The Output Enable signal is off when the inputs are not
active or an error is detected in the function block.
In addition, if the enable switch device is the type that outputs a grip signal and a
release signal, the device’s grip input and release input signal status can be
monitored. The received grip input and release input signals do not affect the
status of the Output Enable signal.
