What causes Siemens SINUMERIK alarm 12090?

Subroutine or predefined function called with parameters when none are allowed. Incorrect syntax in NC program where parameters were added to a parameterless function call. Copy-paste error from a different subroutine call that accepts parameters. Misunderstanding of function signature for predefined subroutines like TRAFOF, TRADON, or similar transformation functions.

How do I fix Siemens SINUMERIK alarm 12090?

1. Locate the exact line in the NC program at the specified block number and identify the function call mentioned in parameter %3 2. Review the subroutine or predefined function definition to confirm it does not accept parameters; consult the SINUMERIK 840D/828D programming manual for the specific function 3. Remove all parameters from the function call syntax; verify the corrected line matches the proper calling convention 4. Check nearby subroutine calls in the program for similar patterns and correct any other instances of parameterized calls to parameterless functions 5. Reload the corrected NC program and verify the alarm clears during program execution at that block

Alarm 12090

Siemens 840D 12090 - Channel block unexpected parameter

The programmed function has been predefined; no parameters are allowed in its call. The first unexpected parameter is displayed. Example: On calling the predefined subroutine TRAFOF (switching off a transformation) parameters have been transferred (one or more).
