The CPU has an internal power supply. This is connected to an external
supply voltage via two terminals located on the front of the unit.
The power supply requires DC 24V (20.4 ... 28.8V). In addition to the
electronic circuitry of the CPU this supply voltage is used for the modules
connected to the backplane bus.
The electronic circuitry of the CPU is not dc-insulated from the supply
voltage. The power supply is protected against reverse polarity and short
circuits.
Note!
Please ensure that the polarity of the supply voltage is correct.
The MPI unit provides the link for the data transfer between the CPU and
the PC. Via bus communication you are able to exchange programs and
data between different CPUs that are linked over MPI.
For a serial exchange between the partners you normally need a special
MPI-converter. But now you are also able to use the VIPA "Green Cable"
(Order-No. VIPA 950-0KB00), which allows you to establish a serial peer-
to-peer connection over the MPI interface.
Please regard the "Hints for the deployment of the MPI interface" in chapter
"Deployment CPU 21x".
The CPUs have an integrated work and a load memory. The memories are
battery-buffered.
Order number Work memory Load memory
VIPA 214-1BC06 48kByte 80kByte
VIPA 214-1BA06 96kByte 144kByte
VIPA 215-1BA06 128kByte 192kByte
In the load memory there are program code and blocks stored together with
the header information.
The program parts and blocks, which are relevant for the running program,
are loaded to the work memory during the program sequence.
