Posted 14 Feb 2018 Hello. I know there were many versions of the C200H series PLC CPUs; and not all the literature is available online. Can anyone help me to confirm what are the differences between C200HG-CPU43 and C200HG-CPU43E? Are these two different CPU part numbers or is it just one? If these are two different CPUs, Can -CPU43E replace -CPU43? Omron list price only shows -CPU43E as an active part number. Share this post Link to post Share on other sites
Posted 14 Feb 2018 From memory ( and that is not always to be trusted), the "E" would have been for an English language unit. There should be a dip switch on the unit to change the C200H-PRO27 handheld between Japanese and English display. "E" units had that switch set to English when shipped, otherwise they are the same. Hope this will help. Share this post Link to post Share on other sites
