- B
  Brett IbarraAug 16, 2025
  If the ERR LED is lit on your ABB Industrial Equipment, it indicates a PLC issue with an event or an unacknowledged alarm. To resolve this, use Automation Builder, an IEC application, or another external access method available in your project, such as a control panel, to identify and acknowledge the diagnostic messages. In Automation Builder, you can access these messages by double-clicking on the device and selecting the 'Diagnosis' tab.

Why does my ABB Industrial Equipment processor module display 'Demo'?
- K
  Kerri LeeAug 26, 2025
  If your ABB Industrial Equipment processor module displays 'Demo' for 5 minutes during each license check, it means the PLC is running in demo mode because a feature license is missing. This demo license is valid for 10 days of PLC run time, after which the PLC will enter stop mode. To resolve this, purchase the missing license or extend the demo license using Automation Builder. Note that the PLC will remain in stop mode until a new license is activated or the licensed features are removed from the PLC application.

Why does my ABB AC500 V3 processor module display 'Grace' every 10 minutes?
- J
  Joshua DouglasAug 31, 2025
  If the display of your ABB Industrial Equipment processor module shows 'Grace' for 5 minutes every 10 minutes, it indicates that the PLC is running in grace mode because a previously available feature license has disappeared. If the grace period expires, the PLC will enter stop mode. To fix this, you need to buy or activate the missing license, and it's recommended to use Automation Builder for activation. The PLC will not return to run mode after entering stop mode until a new license is activated or the licensed features are removed from the PLC application.

Why does my ABB Industrial Equipment CPU display 'noConn'?
- F
  finleyloriSep 9, 2025
  If the CPU of your ABB Industrial Equipment displays 'noConn' (no connection), it indicates a communication problem between the CPU and the display, possibly due to a very high CPU load. This could be caused by an endless loop in the user program or an inactive task watchdog. To resolve this, check the application for loops and operations that consume excessive time, such as file handling. Also, ensure you're waiting for responses from other devices that might be blocking code execution.
