7 ERROR LIST
No. Error Message
There are many nesting
and the conditions of
44 control syntax, or between
control syntax is too long.
(C9017)
The value of the execution
conditions EN of function
45
'*1' is not right. (C9019)
(Function name enters *1.)
Failed to read a system file.
46
(C9020)
Since it is used by the
47
system, Z0 and Z1 cannot
be used. (C9035)
Constant %d is outside the
range of an element
number (%d .. %d).
48 (C9039)
(Element number enters *1,
and the numbers of
elements enter *2 and *3.)

Cause
There are too many nesting levels or conditions in
the control syntax, or the program of the control
syntax is too long.
Example 1: IF D0 = 0 THEN
IF D1 = 0 THEN
• • •
END_IF;
END_IF;
Nesting was performed to 598 or more
levels in the IF statement.
Example 2: FOR D0 := 0 TO 100 BY 1 DO
FOR D1 := 0 TO 100 BY 1 DO
• • •
END_FOR;
END_FOR;
Nesting was performed to 299 or more
levels in the FOR statement.
Example 3: WHILE D0 < 10 DO
WHILE D1 < 10 DO
• • •
END_WHILE;
END_WHILE;
The WHILE statement was nested to 598
or more levels.
Example 4: CASE W0 OF
0: D0 := 0;
1: D0 := 1;
• • •
1491: D0 := 1491;
END_CASE;
1492 or more integer selection values
were used in the CASE statement.
In a specific function, TRUE must always be entered
into execution condition EN but FALSE has been
entered.
Example 1: EI_M(FALSE);
Example 2: DI_M(0);
Example 3: COM_M (FALSE);
The system file is corrupted.
Z0 or Z1 is used.
Example 1: INC_M(M10, D0Z1);
Example 2: Z0 := 10;
The element number of the array is illegal.
Example 1: Word type array label:
IntAry1[255]
IntAry1[K255] := 0;
Corrective Action
The program of the control
syntax is too long. Shorten
the control syntax program,
e.g. reduce the number of
nesting level or reduce the
number of conditions.
Specify the correct value in
execution condition EN.
Reinstall.
Make correction so that Z0
or Z1 is not used.
Correct the specified
constant to within the
element number range.
