Overview of Alarms
NCK alarms
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
20149 [Channel %1: ] Block %2 motion synchronous action: illegal index
Parameters: %1 = Channel number
%2 = Block number
Definitions: An invalid index was used for accessing a variable in the motion-synchronous action.
Example: ... DO $R[$AC_MARKER[1]] = 100
This error occurs if the value of marker 1 is greater than the maximum permissible R parameter num-
ber.
PROFIBUS/PROFINET I/O:
An invalid slot / I/O area index was used while reading/writing data.
Cause:
1.: Slot / I/O area index >= max. number of available slots / I/O areas.
2.: Slot / I/O area index references a slot / I/O area that has not been configured.
3.: Slot / I/O area index references a slot / I/O area that has not been released for a system variable.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Use a valid index.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
20150 [Channel %1: ] Tool management: PLC terminates interrupted command
Parameters: %1 = Channel number
Definitions: Indication that the PLC has terminated an interrupted command (with alarm output) from the tool man-
agement - tool change.
Reaction: Interface signals are set.
Alarm display.
Remedy: For information only.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
20160 [Channel %1: ] Tool management: PLC can terminate only incorrectly
aborted commands
Parameters: %1 = Channel number
Definitions: Indication that the PLC wanted to interrupt an active command from the tool management (tool
change); or that there is no command active for cancel. NCK refuses because the channel status is
either 'active' (cancel is then not allowed), or 'reset' (then there is nothing to cancel).
Reaction: Interface signals are set.
Alarm display.
Remedy: For information only.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
20170 [Channel %1: ] Machine data $AC_FIFO invalid
Parameters: %1 = Channel number
Definitions: the structure of the FIFO variable $AC_FIFO1 - $AC_FIFO10 determined by machine data MD28260
$MC_NUM_AC_FIFO, MD28262 $MC_START_AC_FIFO, MD28264 $MC_LEN_AC_FIFO,
MD28266 $MC_MODE_AC_FIFO cannot be stored in the R parameter field defined in MD28050
$MC_MM_NUM_R_PARAM.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Increase the number of the R parameters
or reduce the FIFO elements.
MD28050 $MC_MM_NUM_R_PARAM = MD28262 $MC_START_AC_FIFO + MD28260
$MC_NUM_AC_FIFO * (MD28264 $MC_LEN_AC_FIFO + 6)
