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.

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

2. 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

3. 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.

1. Set the communication parameter in the register data.

2. Use the SPW command of function instruction to transfer the communication parameter to the file memory in the Ethernet module.

3. 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.
