Posted 21 Aug 2023 I have a customer with a defective C120. I have a program supplied by the customer that was uploaded from the PLC in 2008. If I open the program with notepad, the first line says SWN20 but almost everything else is unreadable. I assume it's a Syswin file. I've tried changing the extension and using the CX conversion program without success. Is there a way to convert this program to a CX One file? If I am unable to convert this program, should I be able to upload into CX-One using a CQM1-CIF02 and C200H-IP007 ? The C120 has a PRO15 programming console attached. The machine has been running but stopped recently. The problem is that the display console shows <RUN> PASSWORD! but the run contact does not close and the light does not come on. Any insight would be appreciated. Thanks!! Share this post Link to post Share on other sites
Posted 22 Aug 2023 You cannot create a CX Programmer project for the C120. It can however upload and download backup files. I don't think this is your best option though since you would not be able to view the ladder program. I cannot confirm that the C120 can communicate via CQM1-CIF02 and C200H-IP007 with any PC software. I don't think it will but we'll see if someone older than me can confirm this. I believe you would need the C120-LK201 and a serial cable. Note: Just because the handheld will work doesn't mean PC communication will. I would use the PRO15 and write the program down in mnemonics. Most likely, the password is not set on the PLC. Press CLR > MON > CLR to get to the mnemonics list. You say the Run light does not come on. I assume you tried switching the PRO15 from PRG to RUN? Share this post Link to post Share on other sites
