Byte offset (P-EXTV-00002)
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. |
