If the Difference Report function is enabled, the Difference Report Before
Download dialog displays (in the same dialog):
• Difference report,
• Source code report.
Based on the information presented in the reports you can either accept or reject the
changes, if you want the download to be carried out or cancelled.
The function is enabled/disabled by right-click the control project folder (root
object) and select Settings > Difference Report.
The Difference report setting is only available for non-High Integrity controllers.
Difference report shows the difference between data downloaded to the controller
and the data present in Control Builder, see Figure. The tree view to the left
shows the parts of the application that have changed. By clicking an item in the tree,
you can display the present controller code to the left, and the new code to the right.
Differences are also indicated by colors (the color coding is explained on the status
bar at the bottom of the report window).
See Control Builder online help for more specific information how to configure
The Difference Report and start value analysis functions is always enabled when
downloading SIL applications to High Integrity controllers.
You Can see the Difference what it has downloaded in Controller while doing download it will show you in Difference Report, in difference report you can able see which line has application modified or which paramter modified in Control Module. It will showing exact difference. In case if you renamed the control module, it will not show you exact diffrence, just it will considere as new control module or if name matches then only diference report matches one to one application & control module
