Analog Latches

Latch Trigger
Input
The latch trigger may be a Boolean 1 or 0. When the value is 0, the block latches the
value of the analog input, and that latched value becomes the output from the block.
When the trigger value is 1, the output is unlatched and equal to the value of the
analog input.
The latch trigger value may be produced by:
a constant
a digital input from a module on the island
a digital output from the virtual module
if the latch is the second block in a nested reflex action (See Nesting Two Reflex
Blocks, p. 36), the latch trigger input may be the output from the first reflex block
