Invalid Option Board Combination

Hva betyr E2-29 ?

The CPU has detected an unsupported or invalid combination of plugged option boards. This hardware configuration error can prevent the CPU from starting or operating correctly, as the system does not recognize the installed modules. This requires physical verification of the setup.

• Inserting an option board that is not supported by the CPU's firmware version or hardware revision.
• Two mutually exclusive option boards (e.g., specific communication modules) are installed simultaneously.
• Exceeding the maximum power draw capacity of the CPU backplane with too many power-intensive option boards.
• Incorrect physical seating or damage to the connector pins of an option board.
• Firmware incompatibility between the CPU and a specific option board's micro-controller.

1. 1

   1. Refer to the CPU's technical manual (e.g., Chapter 3.2 'Option Board Compatibility') for valid combinations.

2. 2

   2. Remove all option boards except for essential ones, then add them back one by one to identify the conflict.

3. 3

   3. Inspect the connectors on the option boards and the CPU backplane for bent pins or debris.

4. 4

   4. Verify the firmware version of the CPU and compare it against the option board compatibility list.

5. 5

   5. Check the power consumption ratings of all installed option boards against the CPU backplane's maximum output.
