Too many external variables declared.
Description | In the list for external variables [EXTV] the number of external variables declared (global and channel-specific) was too high, or the number of existing variables in the parameter P-EXTV-00010 is wrong. The maximum permissible number of external variables can be taken from [SYSP].

Example:

anzahl_belegt 500

#

var[0].name VARIABLE_1

var[0].type SGN32

#

...

#

var[100].name VARIABLE_100

var[100].type UNS32

Possible solutions:

Check if the parameter P-EXTV-00010 contains the correct number of variable declarations

If there are in fact too many variables, you can try to combine variables to variable arrays (same data type) or variable structures (different variable types):

Variable array:

anzahl_belegt 1

#

var[0].name VAR_ARRAY_100

var[0].type UNS32

var[0].array_elements 100

Variable structure:

anzahl_belegt 2

#

struct[0].name STRUCT_DEF

struct[0].element[0].name VARIABLE_1

struct[0].element[0].type SGN32

struct[0].element[1].name VARIABLE_2

struct[0].element[1].type UNS32

#

var[0].name VAR_STRUCT

var[0].type STRUCT_DEF

#

var[1].name VAR_STRUCT_ARRAY

var[1].type STRUCT_DEF

var[1].array_elements 50

Response | Class | 2 | Not all configured variables are generated.
Solution | Class | 3 | Check whether the value in the parameter P-EXTV-00010 is correct. Merge the external variable declarations in the list [EXTV].
Parameter | %1: | Error value [-]
P-EXTV-00010: Number of configured external variables
%2: | Upper limit value [-]
Maximum number of configured external variables
Error type | 1, Error message from NC program.
