Setting the Node Number
With the FINS communications service, when there are multiple Ethernet Units connected to the Ethernet network, the Ethernet Units are identified by node numbers. Use the node number switches to set the node number between 01 and 7E hexadecimal (1 to 126 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 number is factory set to 01. When using the automatic generation method for address conversion, set the node number to the same value as that of the local IP address switches. If this is not possible, then either the IP address table method or the combined method must be used for address conversion. For details, refer to
Bus Unit System Setup. If the FINS communications service is not being used over the Ethernet network, then there is no problem if the node number duplicates that of another Ethernet Unit. The node number must still be set from 01 to 7E, however, or the ERC indicator will light.
Note Turn OFF the power supply before setting the node number.
Setting the Local IP Address
The nodes on an Ethernet network are identified by IP addresses. Each IP address is set with 32 bits of binary data. These 32 bits are divided into four 8- bit fields called octets, and each octet is expressed as four decimal numbers. At
