Data Conversion Error

What does F015 mean?

This error indicates a problem during the conversion of data from one format or type to another. This can lead to incorrect values or an inability to use the data in subsequent operations.

• Attempting to convert incompatible data types (e.g., string to boolean).
• Out-of-range value during conversion causing truncation or error.
• Corrupted source data leading to failed conversion.

Click steps to track your progress.

1. 1

   Verify PLC program logic in data conversion instructions (e.g., MOV, COP, SCL, SCP, CPT) for correct data types, scaling factors, and range limits.

2. 2

   Inspect relevant tag properties and definitions (e.g., base data type, array dimensions) in the PLC project to confirm they match expected usage.

3. 3

   Monitor real-time values of source, intermediate, and destination tags involved in the conversion using the PLC's data monitoring tools to identify where incorrect values appear.

4. 4

   Check I/O module configuration for any analog or specialty modules providing input/output data that undergoes conversion, ensuring their scaling and data format settings are correct.
