Error code E250
Question
A GC-70 series indicator is attached to the device.
I uploaded the project with the drawing tool SCREEN CREATOR 5 to update to the GC-A2x series.
After that, when I executed the restore operation of the upload project, the message “E250 project has not been downloaded” appears and the operation cannot be performed.
What should I do?
Answer
When downloading a project from the drawing software to the GC series HMI, there is a checkbox that says “Project file transmission and upload edit enable”.
This is a feature that prevents end users from unnecessarily editing a project.
If you download without checking here, only the compiled data for HMI to work will be downloaded, and the editable project will not be downloaded to HMI.
On the other hand, if you use the “GC-7x compatibility mode” added in the firmware version of the GC-A2x series V0.1.1.0 Build 03 or later, the GC-A2x series will operate as the GC-7x.
Therefore, if you do not need to modify or change the screen, the compiled data of GC-70 will work as it is.
Please check the version of GC-A2x. In this case, download to GC-A2x is only via USB memory or SD card.
Select “Transfer from CF card” from the menu “Project”->”Upload”->”Dwonload uploading project”.
