Posted 22 Aug 2017 Hi Could anybody tell me if the C500/C120 support tool in CX Programmer uploads the I/O table when it uploads the program from a C500. I have already backed up a program from a C500 using SYSWIN but SYSWIN doesn't allow me to edit, create or generate an I/O table, so when the program is downloaded to a sister machine, I get I/O errors that can't be cleared. Any help grateully received Share this post Link to post Share on other sites
