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

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.
