- the internal memory location is no longer sufficient (e.g. with large arrays)
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Make the following checks:
- Check with the text editor whether the name to be allocated in the active program cycle (main pro-
gram and called subprograms) has already been used.
- Estimate the memory requirements for the symbols already defined and reduce these if necessary
by using fewer global and more local variables.
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
12210 [Channel %1: ] Block %2 string %3 too long
Parameters: %1 = Channel number
%2 = Block number, label
%3 = String in the source block
Definitions: - In the definition of a variable of type STRING, it has been attempted to initialize more than 100 char-
acters.
- In an allocation, it has been found that the string does not fit in the given variable.
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.
- Select shorter string or divide up the character string into 2 strings
- Define larger string variable
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
12220 [Channel %1: ] Block %2 binary constant %3 in string too long
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Binary constant
Definitions: When initializing or allocating the value of a variable of type STRING more than 8 bits have been found
as binary constant.
DEF STRING[8] OTTO = "ABC'H55''B000011111'DEF"
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.
In the window for the alarm message, the first characters of the binary constant are always displayed
although the surplus bit might not be located until further on. Therefore, the complete binary constant
must always be checked for an incorrect value.
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
12230 [Channel %1: ] Block %2 hexadecimal constant %3 in string too long
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Hexadecimal constant
Definitions: A string can also contain bytes that do not correspond to a character that can be entered or one that
is available on a keyboard with a minimized number of keys. These characters can be input as binary
or hexadecimal constants. They may occupy up to 1 byte each only - therefore be < 256, e.g.
N10 DEF STRING[2] OTTO=" 'HCA' 'HFE' "
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.
