17030 Channel %1 block %2 illegal array index 2
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 2nd array index. The
valid array indices must lie within the defined array size and the absolute limits (0 - 32,766).
PROFIBUS I/O:
An attempt was made to read/write data outside the slot / I/O area limits of the stated slot / I/O area.
The following applies specifically: If the alarm occurs while writing one of the parameters
$TC_MDP1/$TC_MDP2/$TC_MLSR,
check whether $MN_MM_NUM_LOCS_WITH_DISTANCE has been set correctly.
$MN_MM_NUM_LOCS_WITH_DISTANCE defines the number of different buffer storage locations
that may be named in Index2.
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.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
17040 Channel %1 block %2 illegal axis index
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A read or write access has been programmed to an axial variable in which the axis name cannot be
unambiguously imaged on a machine axis.
Example:
Writing of an axial machine data
$MA_... [X]= ... ; but geometry axis X cannot be imaged on a machine axis because of a
transformation!
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Deselect transformation before writing the axial data (keyword: TRAFOOF) or use the machine axis
names as axis.
Program Clear alarm with NC START or RESET key and continue the program.
