Omron CJ1W-EIP21 Manual Do Utilizador

With this method, an IP address is not set in the TCP/IP Configuration (left at
its default setting), and an IP address is set in the allocated DM Area words
(the IP Address Display/Setting Area in words m+98 and m+99).

The IP address can be written in the two IP Address Display/Setting Area
words using the CX-Programmer or the Programming Console. To enable the
new IP Address setting, the EtherNet/IP Unit or built-in EtherNet/IP port must
be restarted or the PLC’s power must be turned OFF and then ON again.

Beginning word m = D30000 + (100 x unit number) 

The following table shows the various Unit Setup when only the IP Address
Display/Setting Area is set, and the other TCP/IP Configuration settings are
left at their default values.

This method can be used to set IP addresses from the CX-Programmer. 
For details, refer to 

.

If the IP address is set in the TCP/IP Tab Page, that IP address setting will be
displayed in the IP Address Display/Setting Area (words m+98 and m+99) in
the DM Area words allocated to the Unit/port.
