Pointe Controller User Guide Appendix C: Ladder Diagram Block Reference
377
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 Value 1 (IN1) is
raised to the power of the Input Value 2 (IN2) and the result 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.
