2-1 Overview of Startup Procedure

The following procedure is the same for the CS Series and CJ Series.

Determine the local IP address and address conversion method.

Set the unit number.

Set the node number.

Mount the Unit to the PLC.

Connect to the network using twisted-pair cable.

Turn ON power to the CPU Unit.

Create the I/O tables.

Refer to SECTION 5 Determining IP Addresses.

Refer to 2-2 Switch Settings.

Refer to 2-2 Switch Settings.

Refer to 2-3 Mounting to a PLC.

Refer to 2-4 Network Installation.

Refer to 2-6 Creating I/O Tables.

(See note 3.)

Connecting to the Ethernet Unit without making any settings.

Setting only the IP address (not making other Unit settings) for simple application or operating with only the Programming Console (setting possible with CX- Programmer or Programming Console).

Setting system settings freely (setting possible with CX-Programmer or Web function).

(See note 2.)

(See note 1.)

Use the default IP address.	Set local IP address in DM Area	Set the local IP address in the
	words allocated for CPU Unit Units.
		CPU Bus Unit setup area.

Refer to IP Address in 2-9 Basic Settings.

Refer to IP Address in 2-9 Basic Settings. Refer to 4-2 DM Area Allocations.

Create the routing tables.		Refer to 6-4 Creating Routing	Routing tables must be set to enable the following.
		Tables.	• Using the FINS communications service
	(See note 4.)		• Using the CMND instruction with more than one
			Communications Unit mounted to the PLC.
Perform Unit setup.		Refer to SECTION 3 CX-Programmer Unit Setup.
		Refer to IP Address in 2-9 Basic Settings.
(Create IP router tables.)
	(See note 5.)
Check communications.		Refer to 2-10 Unit Setup for Particular Applications.
(PING command and/or
echo test).

Refer to IP Address in 2-9 Basic Settings.

Note 1: Used mainly when a Programming Console is used to set only the local IP address (set in allocated DM words). When using this method, always leave the local IP address in the CPU Bus Unit Setup Area set to the default value of 0.0.0.0 If the CPU Bus Unit Setup Area contains any other value, any setting made in the allocated DM words will be overwritten with it.

2:The local IP address and other parameters can be set with the CX-Programmer.

3:A PLC Programming Device is required: CX-Programmer, CX-Integrator, Programming Console, etc.

4:The CX-Integrator is required.

5:The CX-Programmer is required.
