can You help me how to give Ipaddress for PLC. Actually i am trying to Change Ipaddress for particular PLC through GTWORKS2 Software but defaultly 2 plc's accessed by same ipaddress(ie 192.168.1.250) so i Am confused which plc i am accessing either first PLC or second PLC.

You must disconnect one of the two PLC's, then set a new address to the PLC that is still connected. Alternatively you can transfer the parameters using serial/usb.

I hope you mean GX Works2, not GT Works2. You can't edit the PLC parameters in the HMI software. Two devices on the same Ethernet network CANNOT have the same IP address. Since you didn't say which PLC type, we can't even tell you where to look for the settings.

I am using two plc's and two Ethernet adapters. PLC type- FX-3U PLC and Ethernet Adapter- FX3U-ENET-ADP.In this when i trying to change the ip address for Ethernet adapters in GX-Works 2 software it does not change the ip address it gives same ip address for both Ethernet adapters .So please help me how to differentiate two Ethernet adapters with different ip addresses.

1. Disconnect one of the Eth cards. 2. Change the IP of the connected Eth card 3. Connect the disconnected Eth card Now you'll have two different IP addresses

Don't forget once you set the IP address in the software to DOWNLOAD the parameters to the CPU. Then reset the PLC and the new IP address should take over.

The module number indicates where the special modules are located. Starts at 0 and increases by 1 for each special module you have connected. If unsure, post the complete setup...
