Setting of External Device

Use the programming software PCwin to set as below.

Settings of I/O Module

Open [I/O Module Settings] of [Parameter] in the peripheral equipment and set the I/O Module identification code.

Setup Items	Setup Description
Slot No.	0
Assignment Item Number	00
Identification Code	B3
Module Type	Special/Communication
Module Name	Time Chart Module/Computer Link/Ethernet/S-NET

Settings of Link Module

Open the [Link Setting] of [Link Parameter] from [Parameter] in the peripheral equipment. Select the Rack No. and Slot No. to which Ethernet module is assigned, and set the link module name to [Ethernet]. If you also use the PC3J Series CPU program divide mode, please select the correct program number.

Setup Items	Setup Description
Rack No.	Option
Slot No.	Option
Link Module Name	Ethernet

Settings of Communication Parameter

Set as below in the communication parameter.

Setup Items		Setup Description
Source Node IP Address		192.168.0.1
Connection	Protocol Open Method	TCP target specified passive
	Source Node Port No.	1025
	Other Node Table No.	Preset other node table No.
Other Node Table	CPU Operation Mode	PC3
	Other Node IP Address	Set IP address of the Display.
	Other Node Port No.	Set the port No. of the Display.

Communication parameter settings include the following two methods.

A. Setting method in the link parameter setting screen of the peripheral equipment.

To use this setting method, the programming software PCwin is necessary. You cannot use other software or tools to set the communication parameter with link parameters.

Select [Detail Settings] of [Link Parameter] from [Parameter] in the peripheral equipment to display [Communication Parameter Setting Screen].

Display the [Ethernet Setting] screen to set each parameter.

Setup Items	Setup Description
Source Node IP Address	192.168.0.1
Connection	Option (1 - 8)
Protocol Open Method	TCP target specified passive
Source Node Port No.	1025
Other Node Table No.	Preset other node table No.
Initialization	Initialize by link parameters

Select [Other Node Table Setting] in the [Ethernet Setting] screen to set other node tables.

Setup Items	Setup Description
Table	Option (1 - 16)
Other Node IP Address	Set IP address of the Display.
Other Node Port No.	Set the port No. of the Display.

B. Setting method by the ladder program

Use the ladder program as below to set the communication parameter.

Set the communication parameter in the register data.
Use the SPW command of function instruction to transfer the communication parameter to the file memory in the Ethernet module.
Use the SPW command of function instruction to set the initial request bit of the file memory in the Ethernet module to ON.

Example of communication parameter is shown below.

Source Node IP Address = 192.168.0.1 (C0.A8.00.01h)

Use Connection No.1, 2, 3 and Other Node Table No.1, 2

Connection 1: TCP active, Port No.6000 (1770h), Other Node Table No.1

Connection 2: TCP target specified passive, Port No.6001 (1771h), Other Node Table No.2

Connection 3: TCP target unspecified passive, Port No.6002 (1772h)

Other Node Table 1: IP Address = 192.168.0.2 (C0.A8.00.02h), Port No. 8000 (1F40h)

Other Node Table 2: IP Address = 192.168.0.3 (C0.A8.00.03h), Port No. 8001 (1F41h)

Example of Ladder Program

NOTE

When the communication parameter is set by both the link parameter and the ladder program, the setting by the link parameter normally is given priority. However, when you select [Initialize by Initial Sequence Program] in the link parameter setting screen, the setting by the ladder program becomes effective even if the link parameter is set.
Check with a network administrator about IP address. Do not set the duplicate IP address.
Please refer to the manual of the External Device for more details.
