2-1 Communication Setting of Omron FINS UDP PLC

Sample PLC Type CJ1W PLC Communication Module CJ1W-ETN21

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

Data items can be organized hierarchically. It is similar to organizing directories and files on your computer's hard disk. The 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.

2-1-1 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.

Please choose [FINS UDP port]

FINS UDP Port of PLC stands for the UDP Port of OPC Server

(1) Destination Network Address: Please type “0” for point to point communication. If the Omron PLC joins the PLC network, then you should fill out the network address. (the range is 0-2)

(2) Destination FINS Node No: Please Type the last number of the IP Address.

(3) Destination Unit Address：Please type “0”

for the point to point communication. If the Omron PLC joins the PLC network, then you should fill out the unit address. (the range is 0-31)

(4) Bank No for EM Area Register：Under normal condition, please write down “0”. The particular setting is required for special EM Area

(1) Source Network Address ： Under normal condition, please write down “0”.

(2) Source FINS Node No：Please Type the last number of IP Address

(3) Source Unit Address：Please write down “0” Because there is only one network unit.

Please choose “FINS UDP Protocol.”

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 (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.

Delay: Amount of time (in milliseconds) between read attempts.

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. The server also can read registers that are not really requested, if this allows it to join

two blocks of requested registers. The numbers entered under Optimizations specify the maximum block length of adjacent unused data.

The Device Parameters directory contains the list of custom device types. Device parameters influence the behavior and performance of the server for the device.

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.

2-1-2 Folder Define

Folders can be used to group items logically. You can configure as many folders as required. Each folder can even have subfolders. Our 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] [Fold]

2-1-3 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 subfolders, 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]

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

Register/ Replay Type: IO Relay, DM Area, Holding Relay, etc

Look for more information in Chapter 1.

Data Type： IO Relay 　 Bool DM Area 　 Int、UINT String 　 When selecting String type, you must specify the data length

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.

This value specifies the data item address (register number) in the device data space. The gray column shows its decimal value.

“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)

If 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).
