PRODUCT NOTICE
Notice of Potential Product Concern
Rockwell Automation issues a Product Notice when it identifies a product(s) anomaly that may cause commercial or customer satisfaction concerns.
ControlLogix 5580 Redundancy Unexpected Power-Up Handler Fault (Type 1 Code 1) with V33.011
Reference: 2021-02-002
Date: February 2021
This Product Notice informs you of a potential anomaly that exists with the ControlLogix® 5580 controllers with V33.011 Firmware. When using a power-up handler program in a ControlLogix 5580 redundancy system, you can experience a Major Fault (T01:C01 – Power-up Fault) on the new primary controller after switchover. To avoid this condition, remove the power-up handler and use the S:FS bit to execute the logic that was contained within the power-up handler.
This is a loss of control and redundancy.

identifying the installed firmware version.
– Description –
If a customer is using a Power-up Handler with a ControlLogix 5580 controller with V33.011 redundancy system and:
• The system is fully Qualified/Synched.
• The controllers are in run mode.
• Both racks are power cycled.
• The racks power up and fully Qualify/Synch.
• And a switchover is caused.
The “new” primary will have a major recoverable fault (Type 1 Code 1). This is a loss of control and redundancy.
The Power-up handler is only executed when the controller powers-up in Run Mode (remote or hard run mode). The Power-up
handler is typically used to handle conditions when the controller was powered down in run mode.
Note: By default, a Logix Controller application does not have a Power-Up Handler defined.
