Important:
This manual refers to the cPu 928 with
MLFB no. -3UA12(12 MHz).

Where to find what in the manual
Chapter l gives an introduction into a processor's mode of operation
and internal structure. It describes the typical S5-135U system
structure as well as the new features and functions of cpu 9 28
Chapter 2 illustrates the user program structure and explains special
features of the sTEP 5 programming language. This is followed by a
description of the various stEp 5 program blocks and how they are
programmed
Chapter 3 contains information on the cyclic program processing in
CPU 928, the organization and storage of programs. A list of the
entire STEP 5 operation set as well as many sample programs have also
been included. (Additional information on STEP 5 operations can be
found in the 'STEP 5 list of operations. Please, also pay attention
to the specifications made under 'Literature references.)
Chapter 4 describes the operating states of cPu 928 (START-UP, RUN,
SToP) and defines the term program level , It explains possible
program levels in the individual operating states of the processor
In addition, you will find important information on time-driven and
interrupt-driven program processing
Chapter 5 contains detailed information on error diagnostic and error
handling. You will find a description of typical errors in START-UP
and run and learn how to detect errors and handle them
The structure of the interrupt stack (ISTAck) and how to evaluate it
is described by means of examples
Chapter 6 deals with 'integrated special functions, and gives many
application examples
Chapter 7 illustrates the structure and the programming of data block
DX 0 which can be used to easily adapt specific features and functions
of cPu 928 to your requirements (incl. sample programs)
Chapter 8 gives detailed information on the memory areas of CPU 928
Experienced users will learn how system data is assigned
Chapter 9 is dedicated to very experienced users who have a profound
knowledge of the system. It contains all the stEP 5 commands used to
access the entire memory via absolute addresses and describes the
individual registers of CPu 928
Chapter 10 gives additional information on multiprocessor operation
and describes the structure and the programming of data block DB 1
which is necessary for multiprocessor operation. The particular fea
tures of test operation are explained at the end of this chapter
Chapter ll describes some online functions which you can call at the
programmer to test your program. We will also turn your attention to
pecularities which may arise in connection with CPu 928
