Too many external variables were declared.

Description

In the list for external variables[EXTV] a too high number of external variables (global and channel-specific) was declared, or the number of available variables in the parameter P-EXTV-00010 is wrong. The maximum permissible number of external variables can be found in [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.
