Siemens 840D 102016 - Operating area change disabled
Alarm 102016 occurs when the control attempts to change operating areas (machine, channel, or axis groups) but the change is blocked by active processes or system conditions. This is typically triggered during program execution when a pending operation, active synchronous action, or system state prevents the requested area transition from completing.

Causes and Fixes
- 1
Check the current NC program status in all channels. Look for programs in ACTIVE, STOPPED, or INTERRUPTED state.
- 2
Press RESET to cancel any active NC program execution or clear the current program block buffer.
Ensure machine is in a safe position before issuing RESET as this will abort current operations.
- 3
Verify no synchronous actions (SYNACT) or coupled motion commands (TRAILON, LEADON) are active using diagnostic screens.
- 4
Return to JOG or AUTO mode and attempt the operating area change again after all processes have cleared.
