NOT
The NOT function ignores the state of the second trigger, normally this shouldn’t be
set to anything, but even if it is set then its condition will be ignored
The not function turns on when trigger 1 is off and turns off when trigger 1 is on

LATCH
Latch is different to the other functions because it’s a latching relay not a Boolean
function.
When trigger 1 is turned on the Latch function turns on, however it will then remain
on even if trigger 1 turns off, i.e. it remembers that trigger 1 has been turned on.
The latch function will only turn on if trigger 2 is turned off, because of this you need
to take the previous state of the output into consideration as well as the current state of
the switches
