P-EXTV-00002 |
Position of external variable in the memory |
Description |
Deviating from the data size implicitly defined by "type” (P-EXTV-00003 ) or the defined data size of a structure, (see Data sets for definition of the elements of a variable type (struct[i].element[j].*)), the position of a variable can be defined in the memory. The indication of this parameter is optional. All variables with byte_offset = –1 are concatenated without gaps (starting with offset 0) in the V.E.memory. |
Parameter |
var[i].byte_offset |
Data type |
SGN32 |
Data range |
0 ... MAX(SGN32) |
Dimension |
---- |
Default value |
-1 |
Remarks |
It is recommended to leave address calculations up to the controller and not to use the parameter. Any memory overlaps caused by incorrect configuration can only be detected by the parameter P-EXTV-00011. |
