Import Instructions for CODESYS

Method 1: Using CODESYS Scripting API (Recommended)

Step 1: Open CODESYS

1. Open CODESYS IDE
2. Create a new project or open an existing one

Step 2: Run Import Script

1. Go to Tools → Execute Script
2. Select codesys_import.py
3. Enter arguments:

   "C:\path\to\your\project.project" "C:\path\to\test_cross_applied_export"
   

4. Click Execute

Step 3: Verify

• Check that PLC_PRG program appears
• Check that GVL with SEVEN variable appears
• Verify the code matches the exported files

Method 2: Headless Execution

"C:\Program Files\CODESYS\CODESYS.exe" ^
  --noUI ^
  --profile="CODESYS V3.5 SP21" ^
  --runscript="codesys_import.py" ^
  "C:\Projects\MyProject.project" ^
  "C:\path\to\test_cross_applied_export"

What Will Be Imported

From test_cross_applied_export/:

• PLC_PRG.prg.st → Creates/updates Program PLC_PRG

  • Implementation: test test4; begin; i = i+1;

• GVL.gvl.st → Creates/updates GVL GVL

  • Variables: SEVEN: INT;

Notes

• If POUs/GVLs already exist, they will be updated
• If they don't exist, they will be created
• The project will be saved automatically after import
