C.6.1 Select minimum value (MIN)
When used in a Ladder Diagram, the MIN block finds the smaller 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 smaller is placed in the Output Value (OUT).
The block function is executed every time the ladder is
scanned
, so long as EN
remains on. If EN becomes off, then OUT remains at its last calculated value until
EN becomes on and the block function is executed again.
