Omron C200HX to CJ1 series

Hi..any expert can advise.

I have a old or not very old Omron C200Hx-CPU85z series which I plan to upgrade.

I know CS1 series is the recommended replaced but I am intertested to use CJ1 series as it will be cheaper and modular.

Does anyone knows if there will be any major issue to change to CJ1 series...Thanks

The conversion to a CS/CJ will be very similar, if not identical. Obviously the hardware is different, but most of everything else would be the same.
The benefit of using a CS1 in this instance, is that you may be able to re-use the IO modules, just swap the backplane & CPU and your 85% done, surely this would be cheaper than going to a CJ, as the wiring can stay the same....
