Process Image Lengths Mismatch (TwinCAT)

Was bedeutet State Variable Bit 2 ?

The K-bus State variable in TwinCAT has Bit 2 set, indicating that the configured process image lengths do not match the actual lengths. This suggests a discrepancy between the data size defined in TwinCAT and the data being exchanged with the Bus Terminals.

• Length of the process image data does not match the configured value.
• Inconsistent data structure between TwinCAT and K-bus terminals.
• Error in the definition of process data object (PDO) sizes.
• Mismatch in the number of bytes allocated for I/O data.

1. 1

   Review the TwinCAT configuration for the K-bus. Ensure that the process data mapping and lengths for all connected Bus Terminals are correctly defined and correspond to their actual capabilities.

2. 2

   Verify the I/O mapping for each Bus Terminal in TwinCAT to ensure correct addressing and data size for input and output variables.
