Was bedeutet A395.11 ?

This flag indicates that memory corruption has been detected within the PLC. When this flag goes ON, the 'Number of Power Interruptions' (A514) will be cleared. This suggests a significant issue with the integrity of the PLC's internal memory or stored data.

• Internal memory read/write errors within the CPU Unit.
• Corrupted program or parameter data due to unexpected events.
• Hardware malfunction affecting the CPU's memory modules.
• Unstable power supply leading to transient memory corruption.

1. 1

   Perform a memory check using the CX-Programmer to diagnose the extent of the corruption.

2. 2

   Upload the existing program and parameters from the PLC, then download a known good backup to restore data integrity.

3. 3

   Verify the PLC's power supply stability, checking for voltage sags, transients, or complete interruptions.

4. 4

   If the issue persists after reloading software and verifying power, replace the CPU Unit.
