Siemens alarm 12140: Channel %1 block %2 functionality %3 not implemented
SINUMERIK channel alarm · Siemens 840D/810D powerline
What it means
The construct parses correctly but the requested functionality does not exist in the installed NCK software or remains unimplemented. It frequently appears when programs are ported between controls or software levels. Replace the construct with a supported alternative or update system software/options.
Likely causes
- Function from another CNC dialect ported unchanged
- Feature requiring newer NCK software than installed
- OEM-specific language extension missing on this machine
