This section describes how to set up the communication parameters for the
serial communication links using the Parameter page of the Link Properties
dialog box.
The following is an example of the Parameter page for a serial direct link.

The following is an example of the Parameter page for an N-to-1 master.

The following table describes each property in the Parameter page of the Link
Properties dialog box for a serial link.
|
Property
|
Description |
|
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. |
|
Panel Address |
The address of the target panel. |
|
PLC Address |
The address of the connected device. |
|
Timeout Time |
The maximum time allowed for the communication driver to
wait for a reply from the connected device. When the
elapsed time exceeds the Timeout Time, the communication
driver assumes the communication failed. |
|
Command Delay |
If the Command Delay is 0, the communication driver
immediately sends the next request to the connected
device when it receives a reply from 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 the communication driver will retry
for each request to get a successful reply from the
connected device. If the number is zero, the
communication driver will use the default retry count. |
|
Fetching Data In Blocks To Optimize The Screen Data
Reading |
The optimization of screen data reading for the serial
links can be determined by the developers. Check the
options and the developer can: a) Disable the
optimization if the connected PLC does not support block
read, and
b) Adjust the criteria of forming read blocks so
the optimization can be suited to each application. |
|
Specify N-to-1 Connection Slave Panels |
This button is available when the link is an N-to-1
master. Click this button to bring up the N-to-1
Connection Slave Panels dialog box. You can define the
slave panels of the N-to-1 connection in the dialog box. |
|
Specify Other Data Sharing Panels |
This button is available when the link is a direct link
and the connected device is Data Sharer (RS485). Click
this button to bring up the Other Data Sharing Panels
dialog box. You can define the other data sharing panels
in the dialog box. |
