Transfer Enhanced Recipe Data
Specifies whether or not to send enhanced recipe data when transferring project data.
Transferring CF/SD card data
Specify whether to send the data in the destination folder to the CF/SD Card in the display unit. If you do not wish to replace the data on the CF/SD Card, clear the check box.
Transfer Project
Auto
The project to be transferred is compared with the project on the display unit. If they are the same project, only updated or added screen data are sent.
When sending a new or different project, the whole project is sent after you click [OK] in the confirmation message.
All
Sends the whole project to be transferred. Overwrites the existing project on the display unit.
Start initialization
Sets the target for initialization when transferring the project.
Variables
Select the check box when initializing the project with the current variables. Current values as well as retentive setting variables are initialized.
When using the SP5000 Series \, even if the check box is cleared retentive variables are initialized. Please be careful.
Backup Memory (SRAM)
Select the check box when initializing the project with backup memory data.
Even when the backup memory (SRAM) check box is not selected, data that is stored in the display unit's backup memory (SRAM) is deleted depending on project transfer conditions. Refer to the following about conditions where data that is stored in backup memory (SRAM) becomes deleted.
34.13.1 Transfer Restrictions
Transfer System
Auto
When you send the project, GP-Pro EX automatically compares between the project system version and the GP system version, and, if necessary, downloads the system program*1, the protocol program*2, and the font*3 to the display unit.
These items are downloaded in the following cases:
When you perform a 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.
Forced transfer
After you format the GP and send a project, GP-Pro EX will forcibly download the system programs*1, protocol programs*2, and fonts *3 to the display unit.
Set up initial connection key
Registers the initial value for the connection key in the [Connection key settings] and [Authentication] dialog boxes. By registering the connection key, you can skip having to enter the connection key every time you transfer. Select this check box to display the registration dialog box.
Click the icon 
to show the connection key. If you want to change the initial value of the connection key, click [Change].
The connection key must meet the following requirements:
8 to 100 characters
Use at least one character from each of the following groups: Lowercase letter (a - z), uppercase letter (A - Z), number (0 - 9), and special character ` ( ) ~ ! @ # $ % & : ; . , - _ { } * + = | < > ? [ ] ' " / \ ^.
You can change the connection key setup on the display unit in offline mode. You cannot change the connection key on the display unit with the [Set up initial connection key] property.
M.5.4 Changing the Connection Key
Authenticate connection key when transferring
Registers the initial value for the [Connection key settings] dialog box’s [Authenticate connection key when transferring] field. Select the check box to authenticate the connection key on the second and subsequent transfers. If the check box is cleared, transfer occurs without displaying the [Authentication] dialog box. The steps for this type of transfer is the same as before GP-Pro EX introduced the connection key.
This setting is enabled only when transferring to a display unit in the following state.
The [Initial Start Mode] or [Welcome] screen is displayed
GP-Pro EX Ver.4.09.120 or earlier project is being transferred
*1 Data used to operate the project on the display unit.
*2 Data needed to communicate with the device/PLC to be used.
*3 Font data used by the project.
Connect the computer and the display unit using 2 cables.
A: User created cable
Create the cable based on the diagram below.
B: RS232C-USB Conversion cable
Use the optional USB-Serial (RS-232C) Conversion Cable CA6-USB232-01 (sold separately).
