Remedy: Press the NC Stop key and select the function "Correction block" with the softkey PROGRAM COR-
RECT. The correction pointer positions on the incorrect block. The symbol to be created or the target
of program jumps (label) must conform to the system specifications, that means the name must begin
with 2 letters (but the 1st sign must not be "$") and may be up to a maximum of 32 characters.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
12430 [Channel %1: ] Block %2 specified index is invalid
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In specifying an array index (in the array definition) an index was used that is outside the permissible
range.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Press the NC Stop key and select the function "Correction block" with the softkey PROGRAM COR-
RECT. The correction pointer positions on the incorrect block. Specify array index within the permis-
sible range. Value range per array dimension: 1 - 32 767.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
12440 [Channel %1: ] Block %2 maximum number of formal arguments
exceeded
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In the definition of a procedure (a subroutine) or in an EXTERN instruction, more than 127 formal
parameters have been specified.
Example: PROC ABC (FORMPARA1, FORMPARA2, ... ... FORMPARA127, FORMPARA128, ...)
EXTERN ABC (FORMPARA1, FORMPARA2, ... ... FORMPARA127, FORMPARA128, ...)
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Press the NC Stop key and select the function "Correction block" with the softkey PROGRAM COR-
RECT. The correction pointer positions on the incorrect block. A check must be made to determine
whether all parameters really have to be transferred. If so, the formal parameters can be reduced by
using global variables or R parameters, or by grouping together parameters of the same type to form
an array and transfer them in this form.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
12450 [Channel %1: ] Block %2 label defined twice
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The label of this block already exists.
If the NC program is compiled off-line, the entire program is compiled block for block. During this pro-
cedure all multiple labels are recognized; this is not always the case with on-line compilation. (Only
the actual program run is compiled here, i.e. program branches that are not passed through in this run
are disregarded and could therefore contain programming errors).
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Press the NC Stop key and select the function "Correction block" with the softkey PROGRAM COR-
RECT. The correction pointer is positioned on the block where the displayed label occurs for the 2nd
time. Use the editor to search the part program where this label occurs for the 1st time, and change
one of the names.
Program Con- Clear alarm with NC START or RESET key and continue the program.
