pm 573 login issue
when I am going online it is showing program has changed . Do you want to download new program?
chage date is also saying todays date though i have not changed anything today.
can anybody tell me why it is coming?
There are a few possibilities:
- PLC boot the project from SD card/internally saved boot project (if used create boot project) which may differ from your PC version
- saved the project even without changes
- executed clear the project or some hareware change
You still can go online without download, but you will see the online version on your PC's project which could differ from that in the PLC
Or you can select download and go online with your PC's version
