Explanation:
When the instruction SET is driven, the specified device is set to ON. No matter the instruction SET
is still driven, the specified device keeps ON. Users can set the specified device to OFF by means of
the instruction RST.
Example:
1. Contact B of X0.0 is loaded, contact A of Y0.0 is connected in series, and Y0.1 keeps ON.
2. When X0.0 is OFF, and Y0.0 is ON, Y0.1 is ON. Even if the operation result changes, Y0.1 still
keeps ON.
