Command Reference: Logic Functions Section 8-4
General Description
This function can be used with Controllers with unit version 1.0 or later
(including Controllers that support EtherNet/IP).
When the input condition to the Reset Set Flip-Flop function block is turned
ON, that ON status is maintained (latched) in the function block and the ON
output is maintained at the Output Enable signal.
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.
Fault Present Output Setting
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.
