Error code
Explanation
0 ESC
The line that has been read cannot be interpreted as a PLC command.
2 ESC
Invalid operand type: An unknown operand type was entered.
The command cannot be applied to the entered operand type.
3 ESC
Operand not found. A type was entered for the operand, but no value.
4 ESC
Operand outside the permissible range. An operand number was specified that lies
outside the value range for this operand.
5 ESC
No limiter after command. The PLC command is followed by further characters that
cannot be interpreted.
6 ESC
No line ending found. The line is longer than 128 characters.
7 SC
Label not defined. A reference was made to a label that has not been defined with
LBL, KFIELD or EXTERN.
8 SC
No block end found. At the end of the program file there are PLC commands that are
not concluded by an EM or JP command. The danger therefore exists that an
undefined program area is executed at run time.
9 SC
Program too long (RAM overflow). The complete length of the program code to be
generated exceeds the storage space available in the control.
10 SC
Assignment in one parenthesis. An attempt was made to assign the result of a gated
operand, although not all opening parentheses were closed.
11 SC
Excessive nesting. An attempt was made to nest more than 16 parenthetical
expressions in each other.
12 SC
Jump in a sequence of gating operations. An unconditional jump was programmed
although the assignment chain begun beforehand had not yet been assigned.

Some of the NC error messages are displayed in code.
In the PLC editor or during compilation of the PLC program, the errors are
displayed with the message Input error X. During compilation of the program
after switch-on or when a run-time error occurs, the blinking error message
Error in PLC program X is displayed.
Classification of errors:
Each error message indicates the time at which the error was recognized:
n
E
Error detected during editing. The line is not formatted.
n
S
Error detected during syntax check in the PLC editor (soft-key compile).
n
(S) Error may have already been detected during the syntax check,
otherwise during compiler run.
n
C
Error is detected during compiler run either after switching on the
control or in the PLC programming operating mode.
n
R
Error detected during run time of PLC program.
