How to convert S7-200 -> S7-300 ?

I'm going down the manual conversion route Dave. It's actually quite a complex program utilising Interrupts etc. Soldiering on though through the stuff I can do. Will post back here with the stuff I'm stuck on!

FYI, interrupts in S7-300 are done through Organization Blocks (OBs). Each OB number handles a specific interrupt.

Cheers sig, I've just been looking at them in S7-200. It just looks like they 'attach' them based on events. The ones I'm looking at just look like Positive / Negative One-Shots so should get away without using interrupts for those.

Just trying to navigate the Siemens site to try and find out how many instructions per second the 226 does so I can work out just how much faster the 300 series is.

Cheers
