1-6 VIGOR PLC Communication Parameters Setting
The default communication parameters of VIGOR PLC is 19200 for communication
baud rate、the parity check bit is Even、the data bit is 7 Bits and the stop bit is 1 Bit. If
you use the extension card in CP2. You can use the VIGOR PLC Ladder Master
diagram to configure the communication settings. Before the configuration, be make sure
the PLC is in 『STOP』 mode.

Enter Ladder Master

Sample
PLC Type VB0-20M
Communication VB-485
module

The Address Space tree control in the Configurator, shown in the figure below, sets
the properties and connection parameters for the following items:

z Ports
z Devices
z Folders
z Data Items

Data items can be organized hierarchically. It is similar to organizing directories

and files on your computer's hard disk. The Vigor Serial OPC Server offers several levels
of hierarchy. The Configurator module uses the terms 「Folder」 and 「Data Item」.
A folder can contain additional folders and also data items. The data items are always the
branches in the tree control hierarchy.
The hierarchical structure of the folders and data items helps to organize the devices and
tags, as shown below.

12
2-1-1 Port Define
A port is equivalent to a physical serial port in the computer. To correctly configure a
port means to set up a serial port as a File name (COM 1, COM2),communication speed
(Baud rate), and protocol characteristics:, RTS flow control, Stop bits and Parity scheme.
When the Parity checking enabled check box is not checked, it will force the server to
ignore the parity bits in the message.
1. Select 「Address Space」 → 「Edit」→「New 」→「Port」
2. You can also use 「Ctrl+T」as the shortcut to create a Port

13
Port Define Operation platform

Item Description
Specify a name of the new device. The special
symbols such as ‘+’、/、*、- are not allowed.

Define the Port number.

The value must match the Baud rate value of Vigor

PLC. The default value of VIGOR PLC CP1 is
19200 bps Baud rate.

The default value of Data bits for VIGOR PLC CP1 is

7 Bits.

The default value of Stop bits for VIGOR PLC CP1 is

1 Bit.

The default value of Parity check bit for VIGOR PLC

CP1 is Even.

14
Particular setting will be required if the device works
under RTS flow control. If not, please choose” Disable”.

Select this item if the device works under CTS for

output flow control. If not, just skip this item.

All of the devices under this port will in the simulation

mode. Simulation function will simulate the real
communication situation between devices and OPC
Server.

Apply: Saves all changes specified in the properties

dialog box.
Reset: Undo the setting configuration
Add New: Add the new Port

15
2-1-2 Device Define
Every device is connected to particular port, so it logically creates the second level in
the Address Space tree. Each device is represented by its symbolic name, and is
uniquely identified by the Address value. It is impossible to have two devices with the
same address connected to one port.
Setting up a device requires configuration of its unique address, type, timeouts and
optimization parameters, as shown in the figure below.

1. Select 「Port 」→「Edit」→「New 」→「Device」

2. You can also press 「Ctrl+D」as the shortcut to create a Device.

16
Device define Operation Platform

Item Description
Specify a name of the new device. The
special symbols such as ‘+’、/、*、- are not
allowed.
The value should be the same as the VIGOR
PLC Station number setting value.

Choose the VIGOR PLC Type

Timeout parameters (separately for reading and

writing data) specify the period of time (in
milliseconds) the server will wait for a response
from the device:
Read/Write: Amount of time (in milliseconds)
the OPC server will wait for a response
17
 (read/write) from the device.
Timeouts to Suspend: The number of
consecutive read/write attempts that
timeout before the OPC server will
suspend communication with the device.

Suspend Period: Amount of time the OPC

server will wait before attempting to
reconnect to the device.
Note: The Suspend Period setting can be
decreased to reconnect faster with a
device that has been restarted, but this
will cause the OPC server to generate
more network traffic while a device is
down.
The server tries to optimize the communication
with the devices by requesting as much data as
possible in one message. Consecutive registers
are merged together into one request for
efficiency.
Define the Parameters. You could do it in detail
in the [ Device Parameters ] on the Tree View.

All of the groups and data items under this

device are in the simulation mode. Simulation
function will simulate the real communication
situation between devices and OPC Server.
Please see
“UMHMIOPCEA.pdf”.

Apply: Saves all changes specified in the

properties dialog box.
Reset: Undo the setting configuration
Add New: Add the new Device

18
2-1-3 Folder Define
Folders can be used to group items logically. You can configure as many folders as
required. Each folder can even have sub folders. The Vigor OPC Server supports up to
three folder levels. The use of folders is not required.
If desirable, the configuration could just contain data items without any folders. But most
likely this will only be useful if the application does not demand too many persistent tags.
Select 「Device」 or 「Folder」 on the Tree View. Press the right key of the mouse and
select 「New」→「Folder」

Folder define Operation Platform

Folder define Operation Platform

Item Description
Specify a name of the new folder. The special
symbols such as ‘+’、/、*、- are not allowed.
All of the data items under this group are in the
simulation mode. Simulation function will simulate the
real communication situation between devices and OPC
Server.
Please see
“UMHMIOPCEA.pdf”

Apply: Saves all changes specified in the properties

dialog box.
Reset: Undo the setting configuration
Add New: Add the new Folder

20
2-1-4 Data Item Define
A Data Item represents a register in the device or a range of registers. A symbolic name
and description is associated with the data item. An OPC client can obtain the data item
description.
The actual OPC item name (tag) is compounded from the Address Space root, the names
of the folder and its sub folders, and the name of the data item. Data items can be
located in any folder, even in the root of the address space.
The steps to create the data item (tag) are as below.

Select 「Device」 or 「Folder」, Press the right button of the mouse, it will show
you the Popup menu. Then select 「New」 →「Data Item」

21
Then define the data Items, the picture is as below：

Item Description
Specify a name of the new data item. The special
symbols such as ‘+’、/、*、’-‘ are not allowed.
Description of Data Item
The Register/Repay type of
Vigor PLC. Please check it
in Chapter 1

Choose the proper data type, if you choose “STRING”,

the data length should be assigned.

From the starting address to access the data by block,

not point to point to access the data. It could speed up
the communication speed. You do not have to define a
lot of items to get the values. Using [ Vector ] function
will let OPC server put the values into the arrays.

22
This value specifies the data item address (register
number) in the device data space.

“Read Only” does not allow you to save new value into
OPC Client.

If the data type is UINT, you can choose the number of

bits and analyze the value and put into this item. Bit#
means the starting Bit No. Count means the constant
Bits number.
To get the data value converted according to a
prescribed form, choose one of the predefined or user-
defined conversions.

Simulation function will simulate the real communication

situation between devices and OPC Server. Executing
“Monitor View” or press F12 as the shortcut, the “Tag
Value” will keep changing for testing the connecting
situation.
To test the client functionality, choose a Simulation
Signal from the Signal drop-down list and check the
Simulate check box. All levels in the Address Space
(port, device, folder, data item) support the process of
simulation (Simulate check box). The parent list in the
tree is superior; it has a higher priority when deciding to
simulate the data item or not. In other words, a data
item is simulated, if it itself has a simulation selected, or
if any of its parents has the Simulate check box
checked. (It may be simulated even if its Simulate
check box stays unchecked). Please look for details in
“UMHMIOPCEA.pdf”.
f checked, the data item will offer constant parameter
value, because Manual setting is of the highest priority.
The changes in the configuration take effect only when
the server reloads the configuration (on startup).
Apply: Saves all changes specified in the properties
dialog box.
Reset: Undo the setting configuration
Add New: Add the new Data Item
