Sequence for the softkey function "Conversion start" on "OK" in detail:
1. Copying the data from the source machine data block (source data objects as selected
above) to the data block of the target file whereby only the data TEA1, TEA2 and TEA4
are considered. The TEA3 and IKA data are not copied.
2. Checking with user if the inch/metric data (target data) are already available.
3. Only the machine data valid for the respective zone are filtered out from the target file,
converted and stored in the destination file. The target file again contains the complete
data. A target file is created for each zone.
4. The machine data to be converted can be configured by the user according to a list
5. Automatic identification of the conversion direction (inch to metric or vice versa) is carried
out via the reference date (MD can be configured). Rejection of the process results if data
are not complete. Therefore, only complete data blocks are accepted.
Source and target name are automatically recorded in the "CONFIG" file. These data recorded
in the "CONFIG" file are loaded to the NCK when the softkey "Switchover function" (see NC
parameter) is pressed.
The machine data – further optimized online and manually – can be stored in the target files
(converted data) via the already present functionality "Save on disk". The user is responsible
for selecting the correct data block.
