Hi,

I'm using studio 5000. I'm trying to figure out the difference between OSR and ONS. Any small ladder example with explanation?

Thank you,
 
Essentially, just the format, and the fact the the OSR needs to have a defined output bit.

ONS can be used in a rung, and everything following it will be triggered once for every false to true transition of the input logic.

OSR, by having a defined output bit, can be used to one-shot multiple later rungs in the scan for each false to true transition of its input logic.
