Internal Device Error

¿Qué significa 16171 ?

This critical error indicates a severe, unrecoverable internal malfunction within the safety I/O module itself. This type of fault typically points to a hardware failure or a fundamental firmware issue that cannot be resolved through configuration or external checks, demanding immediate attention.

• Malfunctioning internal hardware component (e.g., ASIC, memory chip) within the safety I/O module.
• Corrupted firmware image or bootloader sector preventing proper module initialization.
• Over-stress condition (e.g., transient overvoltage beyond 24VDC tolerance) causing permanent damage to internal circuitry.
• Manufacturing defect in the module's core processing unit.

1. 1

   Record the full fault code and module serial number for manufacturer reference.

2. 2

   Power cycle the safety I/O module by removing and re-applying its 24VDC supply voltage at terminals X1.1 and X1.2.

3. 3

   Replace the entire safety I/O module with a new, tested unit if the error persists.

4. 4

   Verify proper grounding of the new module's chassis to the control cabinet's ground rail.
