Siemens 840D 101159 - Remote block in incorrect state
Alarm 101159 occurs when a remote block (typically a subprogram or external NC block) is called or executed while the drive or NC system is in an incompatible operating state. This typically happens when trying to execute blocks during transitions between operating modes, during active reset conditions, or when drive enable signals are not properly established before program execution.

Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Check drive enable status on HMI: Navigate to Diagnosis -> Drive -> Overview and verify all axes show 'AB' (drive enable) status with green indicators.
- 2
Verify PLC interface signals: Check DB31...DBX0.0 (axis enable) and DB31...DBX0.2 (controller enable) are TRUE for all affected axes in PLC diagnostics.
- 3
Perform drive reset: Press RESET on machine control panel, wait 2 seconds, then select reference point approach and home all axes before restarting program.
Ensure work area is clear before homing axes
- 4
If problem persists, perform NCK power-on reset: Navigate to Startup -> NCK -> Power On, execute reset, and re-reference all axes.
NCK reset will clear tool offsets and work coordinate systems - document current values first
