Introduction
A CPU is an intelligent module. Here your driver software is processed.
Depending on your performance needs, you are able to choose between 4
different CPUs. The more power the chosen CPU has, the more user
memory it has. This is composed of load memory for the project
engineering and work memory for the program compiled from the project
engineering.
These CPUs are conceived for middle and large applications with
integrated 24V-Power supply. Additionally every CPU has a MMC slot at
the frontside. Every CPU has a MPI slot and is instruction compatible to
STEP
®
7 from Siemens.
The performance of the CPU series 314...317 corresponds to the S7-300
CPU-series from Siemens (except CPU 318).
This CPUs series allows you the access to the peripheral modules of the
System 300V. Via standardized commands and programs you may request
sensors and control actors. The CPU is parameterized by means of the
integrated MP
2
I-Interface.
The CPU 31x family is available in 4 different CPU versions with each 4
variants:
• CPU 31x SPS-CPU with DP slave
• CPU 31xDPM SPS-CPU with DP slave/master
• CPU 31xNET SPS-CPU with DP slave, Ethernet TCP/IP-Interface,
4port Switch
• CPU 31xNET SPS-CPU with DP slave/master, Ethernet TCP/IP-
Interface, 4port Switch
The following CPU versions are available:
CPU Work memory

CPU 314 96 144
CPU 315 192 256
CPU 316 256 512
CPU 317 512 1024
Note!
The further description in this manual refers to the complete CPU family
CPU 31x. The CPUs 314...317 are functionally identical and they only differ
in their range of memory.
