External power supply error

What does 3010H mean?

An error was detected on the external power supply connected to the I/O module. This could stem from issues with connected devices, wiring, incorrect voltage levels, or an improper power-on sequence relative to the module's own power supply.

• Faulty connected devices drawing excessive current or causing anomalies on the external power supply.
• Improper wiring or loose connections in the external power supply circuit.
• Incorrect or unstable voltage supplied by the external power source.
• The external power supply was not powered on at the same time as the module's main power supply.
