How to connect CX-Programmer with ETH21 ETH11 mode module?

[Milosh]

Hi all.

I use CPU CS1D-H with duplex module CS1d-DPL02.

In main rack I have CS1d-ETH21(ETH11 Mode) module.

Set node addres unit no to 1, and adress node 1f as last segment of IP address 31.

In IO_tabe unit setup address of the module is 192.168.0.31.

After that I change communication settings in CX programmer to Ethernet and IP address like above.

But can not connect to PLC.

What I miss?

Can you ping the card?

Thanks for reply.

I can't ping tha card via Command promt...

Its not CS1D-ETH21. It is CS1W-ETH21(ETH11 mode), my mistake.

I can see it in Cx integrator, but can't ping.

Please check your subnet mask settings. (They must match)

Yes the subnetmask is ok: 255.255.255.0

I set 1 on rotary button x16_1 and F on rotary button x16_0...

I tried with a switch, crossover cable...

The above link is for setting up the unit for FINS communication. 
Note:  The ETN21 is added to the PLC in the ETN21 Mode, not the ETN11 mode.

I tried everything...

Configuration of Unit is good. LNk led ON, RUN led ON, 100M LED on.

I cnt't ping my card. My comp and card is in the same subnet.

I don't know what is the problem...

Finally, I set up address in Unit setup to 192.168.0.31, dial switches set to 1 for x16_1 and F for switch x16_0.

Then I use wireshark...bum...I get Ip address for omron as 192.168.250.31...

Why????

 

Now I can connect with this address 192.168.250.31, but in unit setup is set address 192.168.0.31, and subnet mask 255.255.255.0

 

Im not sure why third segment of IP address is not changed to zero. Instead of that it is 250???

I also tried to change the IP address from web page.

Goto http://192.168.250.31/0 and go to Settings-> System and login with ETHERNET 

After that IP address which is set is 192.168.0.31

and subnet mask is 255.255.255.0

I click on Set and then Regist.

Turn off the whole rack with CPU and ETN21, then on, after that address is not changed.

It's stay 192.168.250.31

I have two guesses :

1. You don't have any battery installed on your PLCs
2. You didn't transfer your IO Table setting to your PLC

I don't know what you mean by clicking "Set" and "Regist". Didn't see any of that in the IO Table window. Typically there will be "Transfer PC to Unit" button to save your changes into PLC.
Make sure when transferring program you also check the IO Table and Special IO Unit Parameters checkbox, or else the IP Address settings will not be transferred.

The 192.168.250.XXX is a default addressing system used by Omron only if the ETN unit parameters is not set manually. The XXX will depend on your Rotary Switch settings (in your case it is 31)

Let's say you've downloaded the settings, in the case if your PLC didn't have any battery, after power cycle the content of D Memory Area which holds the IP Address value might be cleared so the settings will revert back to default.

I check all these settings during transfer.

Yes, but address is not back to 192.168.250.1 as default address. It's displayed as 192.168.250.31?

In IO table I set address 192.168.0.31 as mentioned above. 

Tried via cx programmer, via web page...same behavior.

Finnaly I change IP address.

I use words DM30198, and DM30199 to set IP address.

DM30198 #C0A8 - as 192.168 (first two segments of IP address)

DM30199 #001F - as 0.31 (second two segments of IP address)

When used only rotary switch, it changes only the last segment of IP address - so the address always stays as 192.168.250.xxx where xxx - rotary switch settings.
