Identify the block number shown in the alarm and locate the specific NC program line causing the error.

Check the variable declarations (DEF statements) for all variables used in that line and verify their data types (INT, REAL, BOOL, STRING, CHAR, AXIS, FRAME).

Verify that all assignments and operations use compatible data types. For example, ensure REAL variables receive decimal values, INT variables receive integers, and STRING operations use quoted text.

If type conversion is needed, use explicit conversion functions: TRUNC() or ROUND() for REAL to INT, or declare variables with the correct type from the start.

Implicit type conversion is limited in SINUMERIK; always use explicit conversion functions when changing data types.

Review the system function, cycle call, or subroutine at the alarm location and document all parameters being passed.

Cross-reference with the Siemens documentation or cycle definition to verify the expected data type for each parameter position.

Check for common errors such as: passing R-parameters where machine data addresses are expected, using REAL where AXIS type is needed, or string values without proper quotation marks.

Correct the parameter list by either converting the variable to the proper type or using a variable of the correct data type in the function call.

AXIS and FRAME data types have specific syntax requirements; ensure axis names are used correctly without quotation marks where axis types are expected.

Check if the error involves array access and verify the variable is declared as an array with proper dimensions (e.g., DEF REAL ARRAY[10]).

Verify that all array indices are integer types or expressions that evaluate to integers. Check for accidental use of REAL variables as array indices.

If using indirect addressing or pointers, confirm that the pointer variable is declared with the correct data type and the target variable matches.

Array indices in SINUMERIK must be integer values; using REAL numbers as indices will trigger type errors.

Review array dimension access to ensure single-bracket notation matches the array declaration and multi-dimensional arrays use correct syntax.
