Data integrity

In PLCnext Engineer from version 2023.0, you can enable the project integrity check (hash protection of projects and libraries locally stored on your computer). With activated Enabled checkbox (hash protection is activated), PLCnext Engineer calculates hash codes (numeric value of fixed length that uniquely identifies data) about the project. The project's hash codes are checked for mismatching or missing hashes when opening the project. Depending on the protection level selected here, you will be informed with a warning/error message and the appropriate action will be performed.
With deactivated hash protection (Enabled checkbox deactivated; default setting), PLCnext Engineer does not use hash codes for comparison of project contents. No hash codes are calculated and checked. You will not be informed whether a project has or does not have hash codes. 

Phoenix Contact recommends to enable the hash protection (data integrity check). Proceed as follows:

  • In PLCnext Engineer, open the options menu: ExtrasOptions... 
  • Open the Administration drop-down menu.
  • Click on Data integrity.
  • Activate the checkbox Enabled.

  • Click the OK button.
  • Restart PLCnext Engineer.

Protection level
