7 ERROR LIST
This chapter explains the errors that may occur during conversion of a created ST
program.
For the execution errors that may occur when the ST program is written to the CPU
module, refer to the "MELSEC-Q/L Programming Manual (Common Instructions)",
"QCPU User's Manual (Hardware Design, Maintenance and Inspection)" or "MELSEC-
L CPU Module User's Manual (Hardware Design, Maintenance and Inspection)".
No. Error Message
An unanalyzable character
1
exists. (C1009)
An unanalyzable operator
2
exists. (C1010)
The real number constant
3
is wrong. (C1013)

When conversion error occurs
The error dialog corresponding to the error in the program is displayed.
The maximum number of errors that may occur in a single program is 1000. Errors
in excess of 1000 errors are not displayed in the error list.
About conversion error indication
More than one error may be displayed for a single program statement, or more than
one message may be displayed for a single error.
Conversion error list (error message, cause, corrective action)
The character string that cannot be analyzed exists.
As character strings that cannot be analyzed, there
are the following examples.
Example 1: 2##
The format is wrong.
Example 2: STRING type: STRV1 is defined.
STRV1 := $"abc";
The $ symbol is used.
Example 3: D0 := !10;
The ! symbol is used.
Example 4: J25|\K4X0 := 5;
The | symbol is used.
The operator that cannot be analyzed exists.
Example 1: Y0 : = M0 => M1;
The description of the real number constant is illegal.
As illegal descriptions, there are the following
examples.
Example 1: REAL type : RealV1 is defined.
RealV1 := 1.;
The format of the real number constant
is wrong.
Example 2: RealV1 := 0.1E;
The format of the real number constant
is wrong.
Cause Corrective Action
Correct the character
string.
Correct the operator.
Correct the description of
the real number constant.
