Chapter 5 Configuration of Communication parameters
5.3
Configuration of Ethernet parameters by user program
(1) Setting the dip switch
To configure the Ethernet parameters by the user program, setting dip switch No.4 and No.6 are ON is
required.

CAUTION
- It is possible to access to this module by EH-ETH2 Configurator at this mode but it is not possible to change the
“Ethernet parameters” by EH-ETH2 Configurator.
(2) Table of Ethernet parameters

(3) Setting and referring the table value of Ethernet parameters
The dedicated commands (FUN200 on EH-150 series, XYRW on EHV-CPU series) should be used for setting
or referring the value of Ethernet parameters of this module. These commands handle the data transfer between
internal memory area of CPU and the retained memory of this module. The continuously 55 words of internal
memory is required to set the Ethernet parameters by the user program using these commands.
