Program error

What does PEr mean?

An error has been detected in the program flow of the device. This signifies an internal software issue that prevents normal operation.

• Corrupted internal firmware image due to an interrupted update process or faulty flash memory.
• Incorrectly configured software logic or control sequence (e.g., an infinite loop, invalid memory access) in user-defined programming.
• Hardware malfunction (e.g., CPU, RAM) causing unpredictable program execution or data corruption.
• Stack overflow or heap memory exhaustion in the device's internal operating system, often from complex or resource-intensive operations.
• Unhandled exception or division by zero error within the device's application code, leading to a program crash.

Click steps to track your progress.

1. 1

   Power cycle the device and observe if the error persists, indicating a persistent software or hardware issue.

2. 2

   Re-flash the device firmware with the latest stable version using the manufacturer's specified programming tool.

3. 3

   Load the factory default parameter set (e.g., using parameter P0-01 = 0) to clear any potentially conflicting user configurations.

4. 4

   If user-defined application logic exists, review the program for logical errors, array out-of-bounds access, or recursive calls.

5. 5

   Monitor CPU load and memory usage (if accessible via diagnostics) to identify resource exhaustion as a potential cause.

6. 6

   Perform a diagnostic hardware check if available, or consider sending the unit for service if firmware re-flash does not resolve the issue.
