Newsletter 5/1/2019 - Does the last rung really win?

Does the last rung in a PLC program really "win"?  Many times I've got inquiries from programmers who add a second with the same output to test temporary code because they've been taught that the "Last Rung Wins" and will overwrite anything the first rung does and can't figure why it doesn't operate as expected.  Are duplicate outputs unpredictable?  

What would you like to see a video or lesson on next?  We are looking for ideas, contactus@twcontrols.com

The RsLogix 500 Training Series can be found in our Lessons section.

All the best!
