Hello,

Is there something similar in CX-Programmer to the (N) bit in Siemens programming software? If so, what is it called please?

There are many ways to detect an ON to OFF transition. Right click any contact then choose Differentiate > Down. The DIFD instruction can be used as output only. The DOWN instruction is used in-line. 

I'm not sure what ROL is but the entire Status Word looks very specific to Siemens. What do you want to accomplish?

Hello, thank you so much for your reply. I appreciate it. 

I was trying to use that diff down earlier but it didn't seem to be functioning how I wanted it to. I have since managed to figure it out. Happy days!

Inline instruction "NOT" inverts the rung preceding logic result.
