7. EtherNet/IP Connection Procedure 7.3. Setting up the PLC Set up the PLC. 7.3.1. Hardware Settings Set the hardware switches on the Ethernet/IP Unit and wire the network. Precautions for Correct Use Make sure that the power supply is OFF when you perform the setting up. 19 1 Make sure that the power supply to the PLC and the Switching hub is OFF. *If the power supply is turned ON, settings may not be applicable as described in the following procedure. 2 Check the positions of the hardware switches on the front of the EtherNet/IP Unit by referring to the right figure. 3 Set the Unit number setting The unit number is used to identify individual CPU Bus Units when switch to 0.
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 With the FINS communications service, when there are multiple switches to the following default EtherNet/IP Units connected to the Ethernet network, the EtherNet/IP Units are identified by node addresses. Use the node settings. address switches to set the node address between 01 and FE NODE No.x161: 0 hexadecimal (1 to 254 decimal).Do not set a number that has already been set for another node on the same network. NODE No.x160: 1 *Set the IP address to 192.168.250.1.
The left switch sets the sixteens digit (most significant digit) and the right switch sets the ones digit (least significant digit).The node *By default, the first to third address is factory set to 01. octets of the local IP address are fixed to 192.168.250. The fourth octet is the values that are set with the Node address setting switches.
