Failed to modify the Internet Protocol configuration

At least one of the parameters for the Internet protocol is incorrect. Check your configuration and try again.

Possible errors include:

Host portion of the IP Address is invalid

You entered an invalid Internet protocol address. The IP address entered is reserved for either the network address or the broadcast address.

See IP Address for details about valid Internet protocol addresses.

Invalid Subnet Mask

You entered an invalid subnet mask.

See Subnet Mask for details about valid subnet masks.

The Gateway Address must be on the same subnet as the IP Address

You entered an invalid gateway address.

See Gateway Address for details about valid gateway addresses.

Invalid Domain Name

You entered an invalid character for the domain name.

See Domain Name for details about valid domain names.

Too many characters entered for domain name

The domain name exceeds 48 characters in length.

See Domain Name for details about valid host names.

Invalid Host Name

You entered an invalid character for the host name.

See Host Name for details about valid host names.

Too many characters entered for host name

The host name exceeds 64 characters in length.

See Host Name for details about valid host names.

IP address ranges overlap

The IP address ranges of the Ethernet ports overlap. This error can occur when the controller supports multiple Ethernet ports and you are attempting to add an IP address range that overlaps with a current IP address range of another Ethernet port. For

CompactLogix

5480 controllers, all three Ethernet ports must have non-overlapping address ranges when configured for Dual IP.

The IP address and Subnet mask values that you assign to an Ethernet port establish an IP address range for the port.

Here is an example of IP address ranges that do not overlap.

Here is an example of IP address ranges that overlap.

Change the IP address and/or Subnet Mask so there is no overlap of IP address ranges.

Invalid attribute value

The IP address ranges of the Ethernet ports overlap. This error can occur when the controller supports multiple Ethernet ports and you are attempting to download the IP address settings to the online controller and the newly added IP address range overlaps with a current IP address range of another Ethernet port. For

CompactLogix

5480 controllers, all three Ethernet ports must have non-overlapping address ranges when configured for Dual IP.

The IP address and Subnet mask values that you assign to an Ethernet port establish an IP address range for the port.

Example 1 of an invalid attribute value:

In this example, the error occurs because the newly added IP address range of A1 port will overlap the current IP address range of A2 port. Logix Designer application applies the A1 settings before it applies the A2 settings.

To resolve this error, change and apply the IP address and/or Subnet Mask of the A2 Ethernet port first, and then change and apply the IP Address and/or Subnet Mask of the A1 Ethernet port.

Example 2 of an invalid attribute value:

In this example, the error occurs because the newly added IP address range of A1 will overlap the current IP address range of A2 port and the newly added IP address range of A2 port will overlap the current IP address range of A1 port.

To resolve this error, follow these steps.
