3.3.3 Downloading data
In DDS (as of version 2.0) it is possible to attach a file to your project whose data is automatically
downloaded to the PLC when the program is downloaded.
·
This mechanism is, for instance, used in the Software Package − Cam to download motion
profiles.
Note!
·
With the 9300 Servo PLC the additional data is loaded into the application FLASH.
·
With the Drive PLC the additional data is directly attached to the PLC program because the
Drive PLC does not have an application FLASH.
For the download being executed by the DDS, the following two conditions must be met:
1. The PLC program must have been stopped.
2. The header of the file attached to the project must have the following structure:
Name Data type Data length in bytes Contents
wSizeHeader WORD 2 Header length in bytes
wDataType WORD 2 Data specification identifier
·
This information can be found under C2131 after data has been downloaded.
0 ... 10000 Lenze−spezific data
> 10000 User data
dwVersion DWORD 4 Data version
·
This information can be found under C2132 after data has been downloaded.
dwRealSize DWORD 4 User data length in bytes (without header)
dwTimeStamp DWORD 4 Time stamp of the last data change
·
This information can be found under C2133 after data has been downloaded.
wLicenseInfo WORD 2 Reserved for future extensions
wSizeSymbolicName WORD 2 Length of the symbolic file name
achSymbolicName ACH wSizeSymbolicName Character array including the symbolic file name
·
This information can be found under C2130 after data has been downloaded.
wCopyToRam WORD 2 Selection whether data will be automatically copied into the application RAM of
the PLC after downloading.
