Hello, Should be no problem to replace these TD's. However if the TD parameters are changed(not default) you have a problem. If the device does not work you may need to change the TD addres and/or parameterblock offset. So a backup from plc program may help then.

Hello, The only problem you may face is that you can't upload the program in case your microwin version is older than the version the PLC is programmed with. No risk that the PLC will stop working, be sure you hit the right button (upload) if you hit download you transfer an empty program to the PLC. By the way it's better to upgrade your Microwin version, there is a lot written about CN PLC's and older Microwin versions. The latest version SP8 or 9 can handle older programs, except the ones written in a dos version.
