Corrected anomalies

This list identifies the anomalies that are corrected in the Logix Designer application version 38.00. Use the identification information provided in parentheses to track the anomaly in future releases or for reference when receiving assistance from Customer Support with a related issue.

A tag with a user-defined datatype (UDT) that contains bit overlay members and single-dimension array members cannot be changed/written by any code. Although you cannot create bit overlays in the Logix Designer application, you can add them through an import.

This anomaly first identified in version 28.00.

This anomaly corrected in version 38.00.

Using the

Toggle Inline Value Display

feature in a Structured text routine can slow software performance when toggling the value display on or off. After many repeated toggles of the value display, the software may become unresponsive.

This anomaly first identified in version 31.00.

This anomaly corrected in version 37.00.

When a Guardlink EIP Scanner 432ES AOP version 1.00.34 is already installed on your Logix Designer workstation and you attempt to install version 36, installation errors occur and the installer fails to install AOP core files.

To work around this issue, uninstall the GuardLink EIP Scanner AOP from your Logix Designer application before installing version 36.00. For more information, see

This anomaly first identified in version 36.00.

This anomaly corrected in version 38.00.

For the CompactLogix 5380 Controller, CompactLogix 5480 Controller, and ControlLogix 5580 Controller, when a Structured Text routine includes a comment with nested square brackets "[]" followed immediately by a greater-than ">" character (example

//[commen[t]]>

) the Logix Designer application fails to upload from the controller and displays

Error: Logic reconstruction data may be corrupted.

An example of problematic comment syntax that causes the upload failure is:

This issue impacts Structured Text routines in CompactLogix 5380 Controller, CompactLogix 5480 Controller, and ControlLogix 5580 Controllers.

To resolve this, adjust the comment syntax by reducing the number of square brackets or by removing the greater-than character at the end of the comment. For example, the following syntax allows the upload to succeed:

This anomaly first identified in version 33.00.

This anomaly corrected in versions 35.03, 36.02, 37.01, and 38.

If a Message instruction’s Control tag is defined as program-scoped and the options in the Message configuration > Communication tab for Connection is checked and Cache Connections is unchecked, going offline the ACD file will erroneously indicate that both of these options are checked. Performing a save of the application while online will not correct this.

If the offline ACD file is downloaded to the controller, message instructions that have the Cache Connections checkbox unchecked will now have them checked.

This issue only affects 5380, 5480 and 5580 controllers.

To work around this issue, in the application code use an OTU instruction to reset the EN_CC bit in the message control tag.

This anomaly first identified in Logix Designer version 32.00.

This anomaly corrected in version 38.00.

The Logix Designer application experiences elevated memory & CPU usage and can go into a “Not Responding” state when inline values are enabled in Structured Text.

This anomaly first identified in version 33.00.
