What causes Siemens SINUMERIK alarm 102010?

Part program contains an illegal or unsupported command for the current machine configuration. Parameter or machine data setting incompatible with the commanded operation. Required option or function not enabled on this SINUMERIK control. Incorrect axis assignment or configuration for the commanded function. Software version or compile cycle version mismatch.

How do I fix Siemens SINUMERIK alarm 102010?

1. Note the full alarm message including any parameter values shown (e.g., axis number, block number, channel). 2. Identify the program block or operation that triggered the alarm. 3. Review the SINUMERIK alarm manual for alarm 102010 to identify the specific cause and remedy. 4. Check the relevant machine data parameters referenced in the alarm. 5. If the alarm persists after correcting the program, contact Siemens technical support with the full alarm text and machine data backup.

Alarm 102010

Siemens 840D 102010 - RS232C transmission error has occurred -> error log

Alarm 102010 indicates a communication error has occurred on the RS232C serial interface during data transmission between the SINUMERIK control and an external device (PC, DNC system, or peripheral equipment). This typically results from incorrect interface settings, faulty cables, hardware failures, or protocol mismatches that interrupt or corrupt serial data transfer.

Root Cause Summary

Alarm 102010 indicates a communication error has occurred on the RS232C serial interface during data transmission between the SINUMERIK control and an external device (PC, DNC system, or peripheral equipment). This typically results from incorrect interface settings, faulty cables, hardware failures, or protocol mismatches that interrupt or corrupt serial data transfer.

Causes and Fixes

1
Access machine data settings and verify RS232C interface parameters: MD10200 (baud rate), MD10210 (data bits), MD10220 (parity), MD10230 (stop bits), MD10240 (handshaking protocol).
2
Compare control settings with the external device (PC/DNC) communication parameters ensuring exact match for baud rate (common: 9600, 19200), parity (none/even/odd), data bits (7 or 8), stop bits (1 or 2), and flow control (XON/XOFF or RTS/CTS).
3
Check Setting Data SD42700-SD42799 for V.24 interface configuration and verify correct protocol selection (RTS/CTS hardware handshake vs. XON/XOFF software handshake).
4
After correcting parameters, perform a test transmission with a small file or simple program to verify communication is restored before full operation.
