OMRON CJ1W-PTS51 Process Simulation I/O Module

OMRON CJ1W-PTS51

Note Network Communications Units include Ethernet Units, Controller Link Units,

SYSMAC Link Units, and DeviceNet Units.

Usage

Details

If the nodes are connected to the network, this function allows a computer

based Programming Device (such as the CX-Programmer) to connect online

to PLCs in the network even if the I/O tables have not been created. Since a

network connection is established with the PLCs, setup operations can be

performed such as creating the I/O tables (or editing and transferring I/O

tables), transferring the user program, transferring the PLC Setup, and trans

ferring the CPU Bus Unit Setup.

This function is particularly useful when connecting the CX-Programmer via

Ethernet (using a CS1W-ETN21), because the I/O tables can be created

through Ethernet so a serial cable isn't required and it isn't necessary to

spend extra time establishing a serial connection.

• Applicable Units: All CS/CJ-series CPU Bus Units

• Applicable computer-based Programming Devices: CX-Programmer and

CX-Protocol only

• Applicable functions: Online connections from CX-Programmer and CX

Protocol, and online functions of the applicable CPU Units and CPU Bus

Units

Note When a CS1W-ETN21 or CJ1W-ETN21 Ethernet Unit is being used, the

Ethernet Unit's IP address is automatically set to the default value of

192.168.250.xx, where xx is the FINS node address. After connecting the eth

ernet cable between the CX-Programmer and PLC (without making a direct

serial connection and creating the I/O tables), manually set the computer's IP

address in the Windows Local Area Connection Properties (example:

192.168.250.55). An online connection can be established just by setting the

Ethernet Unit's IP address (192.168.250.xx) and node in the CX-Programmer.

1-6-5 Communications through a Maximum of 8 Network Levels

Previous CPU Units (Pre-Ver. 2.0 CPU Units)

With the pre-Ver. 2.0 CPU Units, it was possible to communicate through 3

network levels max. (see note), including the local network. It was not possible

to communicate through 4 or more levels.

Note A Gateway to the network via serial communications was not counted as a

level
