1.7 Programming Tools
Suitable PGs The following programmers are available for creating your user
program, PG 685, PG 710, PG 730, PG 750 and PG 770. You can
check on the performance and characteristics of these devices in the
catalog ST 59 (see Chapter 13).
Note
Enter the CPU ID for CPU 922 (0010H) in system data word
RS 29 (see Chapter 8) in order to be able to use a PG 615 or a CP
3xx. In this case, you cannot use S flags.
If you do not change the ID, this will lead to erroneous indicators,
e.g. in the case of ISTACK output, or to the loss of some
debugging aids.
In all programmers, the
STATUS test function operates without
restriction only at scan times of
≤ 2.5 s. This value is halved in the
case of parallel operation of 2 programmer interfaces (see
Chapter 11).
Suitable software You can create user programs for SIMATIC S5 programmable
controllers
as follows:
•• In the STEP 5 programming language,
Here you require the STEP 5 programming package along with the
system software STEP 5/ST or STEP 5/MT (description, refer to
/3/ in Chapter 13),
or
•• In a higher programming language:
If you are familiar with programming in higher programming
languages, you can also formulate your STEP 5 program for the
CPU 928B as follows:
- SCL (refer to /12/ in Further Reading, the SCL compiler is
contained in the PG software "S5-DOS/MT" from version 6
upwards.)
You can also create
programs for sequence control systems in a
graphic representation using the
GRAPH 5 programming package
(description, refer to /4/ in Chapter 13).
Depending on the task, you can also incorporate "off-the-peg"
standard function blocks in your user program. The performance and
characteristics of these blocks are described in the catalog ST 57 (see
Chapter 13).
