KRC0926

Common Causes

• Attempting to use an array in a mathematical or logical operation without proper indexing (e.g., using array name directly instead of array[index])
• Passing an entire array to a function that expects a scalar value or single element
• Declaring an array with incompatible data type for the intended operation
• Using multi-dimensional array syntax incorrectly or with wrong number of indices
• Attempting array operations on variables that are not arrays or using non-array syntax on array declarations

Troubleshooting Steps

1. 1Review the KRL program code at the line number indicated in the alarm message to identify where the invalid array operand is used
2. 2Verify that array variables are properly indexed with square brackets (e.g., myArray[1]) when used in expressions
3. 3Check function definitions to ensure array parameters match the expected data type and dimensionality
4. 4Confirm the array declaration statement includes correct syntax and compatible data types for intended operations
5. 5Test the program logic by isolating the problematic section and verifying array usage against KRL language reference documentation
6. 6Recompile the KRL program after corrections to ensure syntax validation passes without errors
