First Scan

4 posts in this topic

Is there a first scan bit. I just want to reset a couple of bits on the first scan when powering up. If not, how would one of you do that? I was thinking of executing a subroutine on start up. I am using a MicroLogix 1200 for this project.

S:1/15 is the fist scan bit. See http://literature.rockwellautomation.com/idc/groups/literature/documents/rm/1762-rm001_-en-p.pdf#page=395.
