ID 21657

Different number of array elements. Array copy not possible.

Description

With external variables (see [EXTV]) complete field variables (arrays) can be assigned to each other. This depends on whether the array variable on the left and right sides are identical. They are identical when the number of elements and the data type are identical.

Example:

Extract from the V.E. configuration list:

var[0].name                      V_ARRAY_1

var[0].type                                 UNS32

var[0].array_elements                       10

var[1].name                      V_ARRAY_2

var[1].type                                 UNS32

var[1].array_elements                       10

var[2].name                      V_ARRAY_3

var[2].type                                 UNS32

var[2].array_elements                        20

Excerpt from the NC program:

V.E.V_ARRAY_1 = V.E. V_ARRAY_3 (error 21657, the number of elements in the arrays of V.E.V_ARRAY_2 and V.E.V_ARRAY_3 are different)

V.E.V_ARRAY_1 = V.E.V_ARRAY_2   ->      (correct, all 10 UNS32   elements of V_ARRAY_2 are copied)
