2.3 CPU 314-6CF23
The CPU 314-6CF23 bases upon the SPEED7 technology. This supports the CPU at pro-
gramming and communication by means of co-processors that causes a power improve-
ment for highest needs.
n
The CPU is programmed in STEP
Ò
7 from Siemens. For this you may use the
SIMATIC Manager or TIA Portal from Siemens. Here the instruction set of the S7-400
from Siemens is used.
n
The CPU has a parallel SPEED-Bus that enables the additional connection of up to
10 modules from the SPEED-Bus periphery. While the standard peripheral modules
are plugged at the right side of the CPU, the SPEED-Bus peripheral modules are con-
nected via a SPEED-Bus bus connector at the left side of the CPU.
n
The CPU has digital and analog input output components. If there is no hardware
configuration available, the in- and output areas starting with address 1024 are
mapped to the address range of the CPU.
The following components are integrated:
–
Analog input: 4x12Bit, 1xPt100
–
Analog output: 2x12Bit
–
Digital input: 8xDC 24V with interrupt capability, 4 counter
–
Digital input/output: 8xDC 24V, 0.5A
n
Modules and CPUs of the System 300S from VIPA and Siemens may be used at the
bus as a mixed configuration.
n
The user application is stored in the battery buffered RAM or on an additionally plug-
gable memory card.
n
The CPU 314-6CF23 is configured as CPU 317-2DP (6ES7 317-2AK14-0AB0 V3.3)
from Siemens.
The CPU has an integrated memory. Information about the capacity of the memory may
be found at the front of the CPU. The memory is divided into the following parts:
n
Load memory 2MB
n
Code memory (50% of the work memory)
n
Data memory (50% of the work memory)
n
Work memory 512kbyte
–
There is the possibility to extend the work memory to its maximum printed
capacity 2MB by means of a memory extension card.
n
The SPEED-Bus is a 32bit parallel bus developed from VIPA.
n
Via the SPEED-Bus you may connect up to 10 SPEED-Bus modules to your CPU.
n
In opposite to the "standard" backplane bus where the modules are plugged-in at the
right side of the CPU by means of single bus connectors, the modules at the SPEED-
Bus are plugged-in at the left side of the CPU via a special SPEED-Bus rail.
n
VIPA delivers profile rails with integrated SPEED-Bus for 2, 6, or 10 SPEED-Bus
peripheral modules with different lengths.
n
Each SPEED-Bus rail has a slot for an external power supply. This allows you to raise
the maximum current at the back plane bus. Only the "SLOT1 DCDC" allows you to
plug-in either a SPEED-Bus module or an additional power supply (307-1FB70).
