Hi

I have been trying to change the IP address on the PLC and HMI to an accepted one used by the industry. I tried the option of assign IP address in the online and diagnostics tab but it does ot do anything. I then changed it in the hardware config and it worked for the PC but not the HMI so now it does not communicate with the HMI. How can i change both the address.

Thank you in advance for any help

Hello Andy,

To change IP address of CPU use http://support.automation.siemens.com/WW/view/en/41737436. This way is very easy. About HMI look at http://support.automation.siemens.com/WW/view/en/43997872 This FAQ doesn't regard directlly your problem, but there has explanation how to set IP address of the panel concerning CPU IP address in order to establish communication.

Best regards,
Hristo Mihalev
