RAM Error - Device Memory

¿Qué significa 1103 ?

The device memory in the CPU module is faulty. This can also occur if a device address outside the valid range is accessed due to indexing, potentially overwriting system device memory. This diagnostic occurs at power ON, after a reset, or upon execution of an END instruction (for specific Qn(H) series models).

• Faulty device memory in the CPU module.
• Device out of range accessed due to indexing, resulting in system device overwrite (Qn(H) series with serial No. 08032 or higher, QnPH with serial No. 08032 or higher, QnPRH with serial No. 09012 or higher).

1. 1

   Implement noise reduction measures for the control system environment.

2. 2

   When indexing is performed, check the value of the index register to ensure it is within the valid device range.

3. 3

   Reset the CPU module and attempt to RUN it again.

4. 4

   If the same error is displayed again after resetting, diagnose for a CPU module hardware fault.
