Storing the user program
The CPU 928B has two areas for storing blocks:
•• User memory: max. 64 Kbytes
The user memory is on a plug-in RAM or EPROM submodule and
contains logic and data blocks (if the user memory is an EPROM
submodule, the data blocks whose data are changed by the user
program must be loaded in the DB RAM).
Data block RAM (DB RAM): max. 46 Kbytes
The DB RAM is an additional memory area for storing data
blocks.
Interfaces to the system
program
Organization blocks are available as interfaces to the system
program for the special types of processing.
