SINUMERIK 840D/840Di/810D Diagnostics Guide (DA) – 11.02 Edition
11.02 1 Alarms
Definitions: This alarm is not a user error.
• 1. If NCU== 0 -> A parameter not equal to zero was not found
• 2. If NCU not equal to zero -> An error which the NC was not able to interpret in the con-
nection to this NCU. The error is output as a number. It is possible that the NCU link
module is running a newer software version than the NC.
The other parameters are used for error localization in the NC/LINK-MODUL software.
Reactions: - Alarm display.
- Interface signals are set.
- NC not ready.
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
Remedy: Make a note of the error text and contact Siemens AG A&D MC, Hotline (tel./fax: see
alarm 1000)
Program Continuation: Switch control OFF - ON.
1100 No valid firmware
Definitions: No memory card or memory card without valid firmware (license) inserted.
Reactions: - Alarm display.
Remedy: Make a note of the error text and contact Siemens AG A&D MC, Hotline (tel./fax: see

1160 Assertion failed in %1: %2
Parameters: %1 = String (path with program name)
%2 = String (line number)
Definitions: This alarm is purely a development alarm and will not appear in a delivered software ver-
sion. For an OEM customer, this alarm could indicate that an alarm has occurred in the
system software. Handling of the 'assertion' allows error conditions leading to this alarm to
be defined in the system software during the development phase. After the development
phase, this alarm output is no longer active.
Reactions: - NC not ready.
- Channel not ready.
- Alarm reaction delay is canceled.
- The NC switches to follow-up mode.
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
Remedy: Check the cause of the error in the specified software component at the specified line
number.
Program Continuation: Clear alarm with the RESET key in all channels. Restart part program.
2000 PLC sign-of-life monitoring
Definitions: The PLC must give a sign of life within a defined period of time (machine data 10100
PLC_CYCLIC_TIMEOUT). If this does not occur, the alarm is triggered.
The sign of life is a counter reading on the internal NC/PLC interface which the PLC
causes to count up with the 10 ms time alarm. The NCK also tests cyclically whether the
counter reading has changed.
