Event Type Error

What does 0x0003 mean?

The 'EventType' input for the application event function block has been set to an unsupported value. Valid types include Fault (1), Warning (2), and Pure (8). This error indicates an attempt to use an unrecognized event classification, preventing proper logging or processing.

• The 'EventType' input for the application event function block in the PLC program is set to an unsupported integer value (e.g., 0, 3, 4, 5, 6, 7, 9) instead of a valid type (1=Fault, 2=Warning, 8=Pure).
• Data corruption on the control bus or within the PLC memory causes an invalid 'EventType' value to be passed to the event function block.
• A custom HMI or SCADA system is attempting to trigger an event with an unrecognized event type enumeration.

Click steps to track your progress.

1. 1

   1. Locate the application event function block in the PLC program and verify the 'EventType' input is set to 1 (Fault), 2 (Warning), or 8 (Pure).

2. 2

   2. Implement data validation in the PLC program to explicitly check the 'EventType' input before passing it to the function block, ensuring it is one of the valid enumerated values.

3. 3

   3. Monitor the data values on the communication bus for the 'EventType' parameter using a network analyzer to detect potential data corruption.

4. 4

   4. If using an HMI for event triggering, confirm the HMI software is sending the correct numeric representation for each event type.
