List interpretation at start-up

All channel parameter lists are interpreted at start-up in a multi-step process based on the associated lists and an internal default setting. Internal machine data may be overwritten as a result of list interpretation whereas entries missing in the interpreted list are retained.

The lists involved are:

The name of the used default list must be specified in the file hochlauf.lis in the entry P-STUP-00034 (default_sda_mds). Entries in this list are identical for all channels.

The sequence of list interpretation is:

  1. Basic initialisation of lists with internal default initialisation setting.
  2. Overwrite the default initialisation with entries from the default list.
  3. Overwrite with entries of channel-specific list of each channel.

The drawing below shows this process again:
