Hardware - SIMADYN D
Edition 03.2001
3.1 CPU module PM5
6DD1600-0AJ0
The CPU module processes general open- and closed-loop tasks. In
addition to
•
max. 8 binary inputs,
it also has the possibility to connect up to
•
2 absolute value encoders
•
2 incremental encoders.
Computational performance:
32 MHz, 32 bit RISC processor
DRAM
4 Mbytes (EDO)
SRAM 64
Kbytes
This CPU module permits fast cycle times of 0.1 ms.
A typical application (e. g. control loop) can be configured in approx. 0.6 ms.
The DRAM contains:
•
program code (is loaded and expanded when the memory module is
initialized)
•
data memory for the operating system, communications, message buffer,
trace function
If the DRAM is not large enough for complex applications, a PM6 (with
8Mbyte DRAM) must be used.
The buffered SRAM (using either a battery in the subrack or an external
battery) contains the following data, which are to be saved during and after a
power failure:
•
operating system error diagnostics („exception buffer“)
•
max. 1000 process quantities configured with function block
SAV
•
data recorded/traced using the message system or trace function
(can be optionally configured on the SRAM)
The program, running on the CPU module, is configured on a PC using
STEP7/HWConfig and CFC. This is then loaded into an MS5 program
memory module (or MS51).
The program memory module is inserted in the module receptacle provided
on the CPU module. The user program can be loaded in 2 ways:
•
via an PCMCIA card installed in the PC-programming adapter (
offline
loading
)
•
directly from the PC via a serial communications connection in the
memory module inserted in the CPU module
(
online loading
)
Order No.
