34.4.1 Procedure - Comparing Project Changes Prior to Transfer

Compares the project currently open in GP-Pro EX to that stored on the display unit connected through LAN.

1. On the GP-Pro EX status bar, click the Transfer Project icon and launch the Transfer Tool.
   

   

   • When edited screen data has not been saved, a dialog box appears for saving screen data.
     Select [Yes] to save and then enter the transfer screen.
     Select [No] to enter the transfer screen without saving. In this case, the last saved screen data is used in the comparison.

2. Click [Transfer Setting] to display the [Transfer Tool] dialog box. Ensure that [Communication Port Settings] is set to [LAN]. Select the [LAN Auto Setting] check box and click [OK].
   

3. Select each IP address of the display unit to compare project data and click [OK].
   

4. In the dialog box that follows, enter the connection key and click [OK]. Click the icon to show the key. Does not display when the [Authenticate connection key when transferring] check box was cleared during setup of the connection key.
   

5. The following [Comparison] dialog box appears and displays the results of the comparison between the PC and display unit.
   
    

   

   • Select the [Show Only Differences] check box. The comparison results show screens that are different.

   • If the logic programs, or settings that affect logic programs, are different in the compared projects, the [Control Settings] will vary. [Control Settings] indicates settings related to logic programs.

   • When comparing projects with different device/PLC configurations, the [Common] tab shows the [Communication Settings] item. Moreover, when comparing projects with indirect devices, the [Device-Specific Settings] item will show.

   • The comparison result for the two projects may appear to be the same on the screen, but they may actually be [Different].
     This is because updated information in the project is managed per screen and per configuration.
     Example:
     Display unit: ABC.prx
     GP-Pro EX: ABC.prx (a project containing a deleted base screen which was saved and re-copied).

   • A message is displayed when there is no difference between projects or there is a difference in the file date/time stamps.
      
     If you open an existing project and save it using [Save As], because the date/time stamp has changed it is considered a different project. If you do not want it to be treated as a different project, in the [Save As] dialog box select the [Do not transfer all if no change in project] check box.

6. After confirming the results, click [Close].
