Preface
Structure of the
documentation
The SINUMERIK documentation is organized in 3 parts:
•General documentation
•User documentation
•Manufacturer/service documentation
This manual is intended as a work of reference. It allows the operator at the machine tool:
- To correctly assess special situations when operating the machine.
- To ascertain the reaction of the system to the special situation.
- To utilize the possibilities for continued operation following the special situation.
- To follow references to other documentation containing further details.
Scope The manual deals with alarms from the NCK (NC kernel), the PLC and the
SIMODRIVE 611D drive.
Further alarms can occur in connection with MMC (Man Machine Communication). These
alarms are displayed on the operator panel in the form of self-explanatory text. They are
subsequently recorded as MMC messages.
For special situations related to the integrated PLC, please refer to the SIMATIC S7-300
system references.
Please contact your local SIEMENS office for more detailed information about documen-
tation for SINUMERIK 840D/810Di/810D and publications, which apply to all SINUMERIK
controls.
Audience This documentation is intended for manufacturers of machine tools with
SINUMERIK 840D/840Di/810D and SIMODRIVE 611D.

!Important
This notice indicates important facts that must be taken into consideration.
Danger
Indicates an imminently hazardous situation, which, if not avoided, will result in death
or serious injury or in substantial property damage.
Warning
Indicates a potentially hazardous situation, which, if not avoided, could result in death
or serious injury or in substantial property damage.
Caution
Used with the safety alert symbol to indicate a potentially hazardous situation, which, if
not avoided, may result in minor or moderate injury or in property damage.

1 Alarms 10.04
1-20 Siemens AG, 2004. All rights reserved
SINUMERIK 840D/840Di/810D Diagnostics Guide (DA), 10.04 Edition
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 softwaren. Handling of the 'assertion' allows error conditions leading to this alarm
to be defined in the system software during the development phase. After the develop-
ment phase, this alarm output is no longer active.
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Alarm reaction delay is canceled.
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.
Reactions: - NC not ready.
- Local alarm reaction.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Check monitoring time frame
in NCK-MD 10100 PLC_CYCLIC_TIMEOUT (reference value: 100 ms).
Establish the cause of the error in the PLC and eliminate it (analysis of the ISTACK. If
monitoring has responded with a loop in the user program rather than with a PLC Stop,
there is no ISTACK entry).
Program Continuation: Switch control OFF - ON.
2001 PLC has not started up
Definitions: The PLC must give a sign of life within a period of time defined in MD 10120
PLC_RUNNINGUP_TIMEOUT (Default setting: 1 sec.).
Reactions: - NC not ready.
- Local alarm reaction.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
