Alarm 101152

Siemens 840D 101152 - Error during communication with NCK

Alarm 101152 indicates a communication failure between the HMI (Human Machine Interface) and the NCK (Numerical Control Kernel). This typically occurs due to network disruption, bus errors, configuration mismatches, or hardware failures in the communication path between the operator panel and the control system.

Safety

Refer to Siemens documentation
Ensure qualified technician performs repairs

Causes and Fixes

1
Check all MPI/Profibus cable connections between PCU (Panel Control Unit) and NCK for loose connectors, damaged cables, or improper termination resistors.
2
Verify bus termination: Ensure 220-ohm terminating resistors are properly installed at both ends of the MPI/Profibus network and switches are in ON position.
3
Use Siemens STEP 7 or HW Config to scan the bus and verify that both HMI and NCK nodes are visible on the network with correct station addresses.
4
Inspect cable shielding for proper grounding and check for EMI sources near communication cables (VFDs, welding equipment, high-voltage lines).
Ensure machine is in a safe state before disconnecting communication cables.
