Posted 10 Aug 2021 Dear Forum, Recently, i needed to backup (Upload) the configuration and the code of some old OMRON PLCs. The PLCs are the C200H-CPU21(See attached picture C200H PLC.jpg). As i understood from the manual, i need to install CX Programmer in my Laptop and connect somehow to the CPU. Also, according to the manual, i should follow the connection described in the attached picture (Connection Diagram.jpg). I don't have the C200H-IP007 interface. Can you tell me what kind of cables (combination) do i need to perform the connection to a PC? Do i need to buy the C200H-IP007 interface? Any help will be acceptable.

Posted 11 Aug 2021 For a C200H, you will require a host link, either a rack mounted type (would have to turn the PLC off to mount it) or a 3G2A6-LK201E CPU mounted portable host link. You may also require a stand off to lift the host link above any I/O cards that are mounted next to the processor. You may be able to find these on E-bay. And then make a cable to use with it.

Thank you for your answer. So if i understood correctly i need to buy this: And mount it somehow to the PLC Rack. Can you tell me where can i mount it? My PLC Rack is in the attached picture: Thank you again! Share this post Link to post Share on other sites
Posted 11 Aug 2021 (edited) Looking at the picture, I would say no. That host link unit goes into the rack like an I/O card. I am not seeing an open slot. Edit: Reading the rest of your post, you should be able to remove one of the OCxxx modules to install the host link. gtsuport Edited 11 Aug 2021 by gtsuport Share this post Link to post Share on other sites
Posted 11 Aug 2021 No - one of these. https://www.ebay.com/itm/284394346071?hash=item4237395657:g:SyEAAOSwsDthCB~E You will probably have to take the terminal blocks off a couple of those card to get it to fit though or buy a stand off adaptor - cannot remember the catalogue number. I have all this old stuff in my shed - have not used it in 15 years. Share this post Link to post Share on other sites
Posted 12 Aug 2021 The adaptor that Bob refers to is a PRO-CON BASE part number BP001. https://www.ebay.com/itm/Omron-C200H-BP001-Pro-Con-Base-/124570147226 Share this post Link to post Share on other sites
Posted 14 Aug 2021 Thank you for your answers. Can you make a sample diagram (Even in ms paint) for the hole solution for connection to a PC? In my mind there is the following diagram: Can you Please Confirm this Diagram? Do i need a specific RS232C Cable for connecting 3G2A6-LK201-E and my PC? Can i use the RS232 to USB Converter from Prolific? Thank you in advance! Argyris Share this post Link to post Share on other sites
Posted 14 Aug 2021 You will need to make up a cable - non standard. Somewhere in the files section there is an article on how to make the cable. No time to find it right now - going to work. Share this post Link to post Share on other sites
