Internal Error (SM560-S)

What does E2-10 mean?

The SM560-S Safety PLC has encountered an unspecified internal error. This indicates a system malfunction that prevents normal operation and requires intervention.

• Unspecified internal hardware fault within the SM560-S module, potentially transient.
• Corruption of the operating system firmware after a power event.
• Temporary internal bus error due to electromagnetic interference (EMI).
• Software deadlock or exception within the Safety PLC's internal processes.
• Overheating of the SM560-S module due to inadequate ventilation in the control cabinet.

Click steps to track your progress.

1. 1

   1. Perform a power cycle of the SM560-S module (turn 24VDC supply off for 10 seconds, then on).

2. 2

   2. Inspect the installation environment for excessive vibration or strong electromagnetic fields (EMI sources) near the PLC.

3. 3

   3. Verify the event log in the engineering software for specific internal sub-codes or associated error messages.

4. 4

   4. Re-download the current application program and firmware to the SM560-S module.

5. 5

   5. Replace the SM560-S Safety PLC module if the internal error persists after these steps.
