Overview of Alarms
NCK alarms
17018 Channel %1 block %2 incorrect value for parameter %3
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Parameter name
Definitions: An incorrect value has been assigned to the stated parameter.
Only the following values are permissible for the parameter $P_WORKAREA_CS_COORD_SYSTEM
=1 for workpiece coordinate system
=3 for settable zero system.
Reaction: Interpreter stop
Interface signals are set.
Alarm display.
Remedy: Assign another value.
Program Clear alarm with the RESET key. Restart part program
Continuation:
17020 Channel %1 block %2 illegal array index 1
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: General:
A read or write access has been programmed to an array variable with an invalid 1st array index. The
valid array indices must lie within the defined array size and the absolute limits (0 - 32,766).
PROFIBUS 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 slot / 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.
The following applies specifically: If the alarm occurs while writing from one of the parameters
$TC_MDP1/$TC_MDP2/$TC_MLSR,
check whether $MN_MM_NUM_DIST_REL_PER_MAGLOC has been set correctly.
$MN_MM_NUM_DIST_REL_PER_MAGLOC defines the number of different Index1 statements that
may be made for an Index2 value.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Correct the specification of array elements in the access instruction to match the defined size. If an
SPL is used in Safety Integrated, the field index via optional data may be subject to additional
restrictions.
Program Clear alarm with NC START or RESET key and continue the program.
