FaultPresent
The ON status is maintained in the function block, so the Output Enable signal
stays ON even if the input condition goes from ON to OFF.
The signal maintained in the function block is turned OFF when the function
block's RESET condition is turned ON.
A Fault Present output can also be used in programming.
To enable this output, select the Fault Present checkbox on the Out Point Tab
Page of the function block properties dialog box.
