Data that is stored in the Display's backup memory (SRAM) will be deleted when transferring a project based on any of the following conditions.
Transferring when the [Backup Memory (SRAM)] in [Initialize] check box is selected in the [Transfer Settings] dialog box in the [Transfer Settings] tab.
When transferring after making changes to the operation log, alarm, sampling, and internal device backup settings
When transferring after selecting [All] in [Transfer Project]
When transferring after selecting [Forced] in [Transfer System]
When sending a different project
When sending a project, the necessary system programs, protocol programs, and fonts are downloaded to the display unit. The transfer will take a few moments.
Downloads occur in the following cases:
When you perform transfer when the display unit has no data (factory default)
If the system program (Runtime) version stored on the display unit is older than the GP-Pro EX version.
When old versions of protocol programs (drivers) are stored in the display unit, or when project device/PLC settings have been added or changed.
When a font not in the display unit was used in GP-Pro EX.
When a download occurs, the display unit is reset. After restarting, the transferred screens appear.
The project files just converted via the Project Converter have a different data structure than the project files saved with GP-Pro EX.
Therefore, when you send project files to the display unit, then save or edit them, and re-send them to the display unit using GP-Pro EX, the system and protocol programs are downloaded. This happens even if you are not changing the system or communication settings.
When the display unit is offline, the project cannot be transferred. However, when [Transfer]-[Transfer Project File] is performed offline, you can perform a transfer.
During the transfer, the display unit changes to Transferring mode and communication with devices/PLCs is suspended.
When a problem is found with the system program on the display unit, an error message appears on the display unit. Transfer the project file again.
You cannot transfer the project file to a different model. To perform transfers even between display units, except for GP3200 Series, one of the following conditions must apply.
Models that do not support the control feature.
Models equipped with DIO board
Models with FLEX NETWORK connections
For GP-3300 Series models, when [Revision] is set to Rev*-4 or later, the transfer fails if a model before Revision 4 is used. However, AGP3310T/3360T models can transfer project files regardless of revision.
