Access algorithm for reading objects
Object 20.2 written with value 0 (object 20.2 is a counter that specifies the next
object to be read; the starting value is 0).
Read object index and subindex in object 20.5.
Format I32 of Object 20.5:
Not assigned
Index (high byte)
Index (low byte)
Subindex
Read the object with the index and subindex read in object 20.5 and in save it in
a table with the following structure: Index (2Byte), Subindex (1Byte), Contents
(16Byte).
Read the next object-Index and subindex in object 20.5.
....
This must be performed until index = 0xFFFF and until subindex = 0xFF.
Writing objects
Write the entire table to Compax3. Each index and subindex is written with the
value stored in the table.
It should be noted in this regard that each time an object is written, the internal
buffer must first be written with DPZ=1, 2, 3 and then the entire order is written with
DPZ0.
