Example of a Fixed File Structure in a Manufacturing
Process
A fixed file structure in the manufacturing process is distinguished by the fact that
the individual SLGs only perform READ or WRITE/UPDATE functions on the MDS.
Commands such as DIR, MDS-STATUS, ASM/SLG-STATUS, DELETE, FORMAT
or CREATE are only carried out at “i-points” (information points) in the system in
order to check the incoming and outgoing MDSs. Further advantages of this
system configuration:
S
Time-consuming operations such as FORMAT occur at the “i-point” and not in
the production process.
S
Since the same file structure is present on every MDS, this can be written to the
MDS at the “i-point”.
S
If the file structures on the MDS are structured accordingly, the checksum (and
thus also the dir FAT) always remains the same. By using the LOAD
and MOVE commands an MDS can also be processed dynamically.
S
At the end of the production process (SLG 5 in the following figure), an MDS
can be processed again at the “i-point” if required.
