Incorrect Command Parameters

¿Qué significa F012 ?

This fault indicates that the parameters provided with a command are incorrect or invalid. This could mean values are out of range, of the wrong type, or missing, preventing the command from being executed successfully.

• Command parameters outside of the acceptable range for the target function.
• Data type mismatch for a command parameter.
• Missing required parameters in the command instruction.

1. 1

   Verify the PLC program logic to identify the specific instruction or command that is generating the F012 fault.

2. 2

   Inspect the parameters used by the identified instruction, checking their current values online to ensure they fall within the expected range and data type definition.

3. 3

   Check any upstream logic or HMI/SCADA inputs that provide values to these parameters, ensuring data integrity and proper scaling/conversion.

4. 4

   Monitor the execution of the faulty instruction in online mode to observe the exact conditions and parameter values immediately prior to the fault triggering.
