Omron Sysmac S6 Program

[Jim Lewellyn 0]

I am converting several Sysmac S6's to AB Compact Logix.  I pulled the S6 programs out using a Pro16 console.  I have figured 99% of it out.  But, there is one rung that has me a bit stumped.  Here it is:

LD 7

AND NOT 8

AND 71

AND TIM 2

LD NOT 72

LD NOT TIM 2

OR LD

LD NOT 7

OR LD

AND 8

OR LD

OUT 74

The final OR LD (prior to OUT 74) is what has me stumped.  Any help will be greatly appreciated!

For some reason, I cannot post a picture here.  So, here is a link:  https://omca.box.com/s/9golymrzwszr4l6u3bbnqx9f61g79beg

I think the drawing is correct.  My mneumonics are a bit rusty.  Edit: Yes, I just entered it (in mneumonics) into CX-Programmer with different addresses (to work with the newer PLC) and it looks like my hand drawn image.

Thank you very much Michael!  That makes sense to me now.  I have not done any boolean programming since the mid 80's, so I am really rusty (and old).
