7. EtherNet/IP Connection Procedure
11
7.2. Setting Up the PLC
Set up the PLC.
7.2.1. Hardware Settings
Set the hardware switches on the PLC and wire the network.
Precautions for Correct Use
Make sure that the power supply is OFF when you perform the setting up.
1
Make sure that the power supply
to the PLC is OFF.
*If the power supply is turned
ON, settings may not be
applicable as described in the
following procedure.
2
Check the hardware switches
located on the front panel of the
EtherNet/IP Unit by referring to
the right figure.
3
Set the unit number setting
switch to 0.
The unit number is used to identify individual CPU Bus Units when more than
one CPU Bus Unit is mounted to the same PLC. Use a small screwdriver to
make the setting, taking care not to damage the rotary switch. The unit
number is factory-set to 0.
4
Set the node address setting
switches as follows:
[NODE No.x16
1
]: 0
[NODE No.x16
0
]: 2
IP address: 192.168.250.2
*By default, the first to third
octets of the local IP address
are fixed to 192.168.250. The
fourth octet is the values that
were set with the node address
setting switches.
With the FINS communications service, when there are multiple EtherNet/IP
Units connected to the Ethernet network, the EtherNet/IP Units are identified
by node addresses. Use the node address switches to set the node address
between 01 and FE hexadecimal (1 to 254 decimal).Do not set a number that
has already been set for another node on the same network.
The left switch sets the sixteens digit (most significant digit) and the right
switch sets the ones digit (least significant digit).The node address is
factory-set to 01.
Default IP address = 192.168.250.node address
With the factory-default node address setting of 01, the default IP address is
192.168.250.1.
