The result of finding the smaller of
the two input values.
NOTE: This function does not check for bit register overflow. You can assign any
variables you wish, but mixing variable sizes – for example, a 32-bit input and an
8-bit output – may result in unusable output.
C.6.2 Select maximum value (MAX)
When used in a Ladder Diagram, the MAX block finds the larger of two inputs
and sends the result to output.
Select the tool (from the Selection Blocks toolbar) and click on a ladder rung
to insert the following block:
Once the block is inserted, you can double-click on it to configure it.
Functional Description
This block always passes the Enable input state (EN) through to the Enable Out
output state (ENO) without change; when EN becomes on, ENO is turned on, and
when EN becomes off, ENO is turned off.
When EN becomes on, the block function is executed: the Input Values 1 and 2
(IN1 and IN2) are compared and the larger is placed in the Output Value (OUT).
