3.4 File and Program Management
Read-in initialization program
NOTICE
Data loss
If the file is read-in with the name "INITIAL_INI", then all data that is not supplied in the file is
initialized using standard data. Only machine data is an exception. This means that setting
data, tool data, ZO, GUD values, ... are supplied with standard data (normally "ZERO").
For example, the file COMPLETE_TEA_INI is suitable for reading-in individual machine data.
The control only expects machine data in this file. This is the reason that the other data areas
remain unaffected in this case.
Loading initialization programs
The INI programs can also be selected and called as part programs if they only use data of one
channel. This means that it is also possible to initialize program-controlled data.
