Chapter 5 Configuration of Communication parameters
5.2.4
Setting of Dip switch
To set Ethernet parameters by EH-ETH2 Configurator, set
No.1 ON
,
No.2,3 OFF
of dip switch.
In this mode,
No.4 to 8 means lower 5 bits of IP address
. Furthermore remained higher 27 bits of IP
address is fixed. Figure 5.3 shows the temporary IP address.

Figure 5.3
Temporary IP address at the time of the Ethernet parameters setting by EH-ETH2 Configurator
As Figure 5.3 shows, the temporary IP address is selected in the range from [192.168.0.1] to [192.168.0.31].
Table 5.3 shows the example of DIP switch setting. After setting the dip switch, power PLC on.

Caution
- IP address "192.168.0.0" is special address. Do not set bit 4 to 8 all OFF at bit 1 ON and 2,3 OFF of dip switch. In this
condition, when EH-ETH2 is power on, STS LED 4 times a cycle blinking, and IER LED turns on.
- IP address set by dip switch is used temporary to access EH-ETH2 Configurator. This setting of dip switch is not
stored to FLASH memory of EH-ETH2.
- When you add EH-ETH2 to Network of established, be careful to the duplicated IP address.
