3 Assigning Device Variables for CJ-series Units
3-16
CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (W495)
Use the following variable to check or set the IP address of the EtherNet/IP Unit.
The IP address is stored as shown below.
If the IP address is set to a value other than 0.0.0.0 in the TCP/IP Configuration, this area will act as
an IP Address Display Area and the IP address set in the TCP/IP Configuration will be read and
stored here when the power is turned ON or the Unit is restarted.
If the IP address in the TCP/IP Configuration is set to 0.0.0.0, this value is read by the EtherNet/IP
Unit when the power is turned ON or the Unit is restarted and is used as the IP address.
If the IP address in these words and the TCP/IP Configuration are both set to 0.0.0.0, the default IP
address (192.168.250.Node_address) will be used. For details on the IP address settings, refer to
Section 4 Determining IP Addresses.
Precautions for Correct Use
Precautions for Correct Use
•
If the IP address is set to a value other than 0.0.0.0 in the TCP/IP Settings, that address is
written to this variable even if you set the variable to a different IP address.
•
It is not possible to set the following IP addresses.
•
IP addresses where all network number bits are 0 or 1.
•
IP addresses where all host number bits are 0 or 1.
•
IP addresses where all subnet number bits are 1.
•
IP addresses that start with 127 (7F hexadecimal, e.g., 127.35.21.16).
