Project Synchronization Errors

Project synchronization is required for the Logical Protocol Modes. Without it, the driver does not have the

information necessary to perform Logical reads/writes. Each error below is preceded with the following:

"The following error(s) occurred uploading controller project from device <device name>. Resorting to symbolic

addressing."

Project Synchronization Errors

Encapsulation error occurred while uploading project information. [Encap. error=<code>].

Error occurred while uploading project information. [CIP error=<code>, Ext. error=<code>].

Framing error occurred while uploading project information.

Invalid or corrupt controller project detected while synchronizing. Synchronization will be retried

shortly.

Low memory resources.

Project download detected while synchronizing. Synchronization will be retried shortly.

Unable to read <element> element(s) starting at <address> on device <device name>. Native tag

size mismatch.

Unable to read tag <tag name> on device <device name>. Native tag size mismatch.

Unable to write to tag <tag name> on device <device name>. Native tag size mismatch.

Encapsulation error occurred while uploading project information. [Encap.

error=<code>].

Error Type:

Warning

Possible Cause:

The device returned an error within the Encapsulation portion of the Ethernet/IP packet while uploading the

controller project.

Solution:

The solution depends on the error code that is returned. If the problem persists, contact Technical Support.

Note:

A project upload is required for the Logical Addressing Modes.
