Create projects so that the total constant communication traffic of connected display units does not exceed 8090. If the total constant communication traffic exceeds the upper limit, the slave unit attempting connection will be refused access. In addition, if the upper limit is exceeded by the master display unit only, slave display units cannot be connected.
To calculate data traffic, refer to the following.
7.6.2 Procedure - How to Calculate the Communication Traffic
Please refer to the Settings Guide for details.
5.4.7 System Settings [Display Unit] - [Extended] Settings Guide
Prepare projects for respective display units to be transferred. Create all the projects using the same version of GP-Pro EX, with the same settings in the [System Settings], [Peripheral Settings] link's [Device/PLC].
If you control the same PLC/device address in parts on multiple display units, it may not operate properly.
For example, if you set up the same address in the Data Block Display Graph's control word, even though you update the graph on the Master display unit the graph will update on Slave display units but not the Master display unit. To prevent this type of behavior, use a different address on each display unit.
If the [Reflect in Device/PLC] check box is selected (accessible from [System Settings], [Display Unit], [Display Settings] tab), and the same items are used on Master and Slave display units, the [System Area Start Address] will be the same for all display units.
For example, if you change a shared screen number, the Master and all the Slave display units will synchronize their screen displays.
Display Unit Settings
To use the Ethernet Multilink feature, Ethernet settings such as the IP address and port number must be set up on each display unit.
Switches to offline mode.
M.1.2 Entering Offline Mode
From [Main Unit Settings], touch [Ethernet Local Settings] to set up the IP address.

GP-Pro EX Settings (Master Display Unit)
From the [Project] menu, select [System Settings] and [Display Unit], then click the [Extended Settings] tab.
From [Ethernet Multilink Settings], select the [Enable Ethernet Multilink] check box.
From [Action Mode], select [Master].
When you want to limit the slave units you can communicate with from the master display unit, click [Filtering] and enter the IP addresses of slave display units whose connections are allowed. (For example, 192.168.0.10)
Create screen data and transfer it to the display unit.
GP-Pro EX Settings (Slave Display Unit)
From the [Project] menu, select [System Settings] and [Display Unit], then click the [Extended Settings] tab.
From [Ethernet Multilink Settings], select the [Enable Ethernet Multilink] check box.
From [Action Mode], select [Slave].
When the GP-Viewer EX feature is enabled, you cannot select the [Slave] option. From the [System Settings], [Display Unit], [Remote Viewer] tab, disable [Remote Viewer].
In the [Master IP Address] field, enter the IP address of the master display unit. (For example, 192.168.0.1)
Create screen data and transfer it to the display unit.
You cannot use Ethernet Multilink to connect a device/PLC that is not supported by the slave display unit.
