This section describes how to set up the communication parameters for the serial communication links using the link screen in the target panel. The default setting of the link screen is transmitted to the target panel along with all the other data when you download an application.

You can press the corresponding Link button on the Panel Setup screen to bring out the link screen. If the link is a serial link, the target panel will display the serial port parameters screen. The following is an example:

The screen for a serial link appears with the following options:

Property	Description
Communications	Select False if you want to disable the communication between the target panel and the controller. When communication is disabled, the target panel doesn’t communication with the controller but can still display screens.
Port	Select either COM1 or COM2 or COM3 to specify the serial port of the target panel that is connected to the controller. The default setting is COM2.
Baud Rate	The baud rate used.
Data Bits	The number of data bits used.
Parity	The scheme of parity used.
Stop Bits	The number of stop bits used.
Command Delay	If the Command Delay is 0, the communication driver sends the next request immediately to the connected device after it received the reply of the last request. If the Command Delay is nonzero, the communication driver delays for the specified amount of time before sending the next request to the connected device.
Retry Count	The number of times that the communication driver will retry to get a successful reply from the connected device for each request. If the number is zero, the communication driver will use a default retry count.
Timeout Time	The maximum time allowed for the communication driver to wait for the reply from the connected device. When the elapsed time exceeds the Timeout Time, the communication driver assumes that the communication failed.
Panel Address	The address of the target panel.
PLC Address	The address of the connected device.
