How do I save a PLC project automatically and open an auto-save file?

1. Click “Tools” and select “Options” in the ISPSoft.


2. In Project Setting, select “Save Time Interval” for Auto-save Project to save the project in a defined time interval as a *.~bak file.
You can select “Auto-save before Compiling” per your needs.


3. Find the *.~bak file under the project directory and rename it to *.isp to open it in the ISPSoft.
