n The power supply is protected against polarity inversion and over-
current.
n The internal electronic is galvanically connected with the supply
voltage.
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. The deployment of this external
power supply at the CPU 314-6CF03 is not permitted!
9pin SubD jack:
n The MPI interface serves for the connection between program-
ming unit and CPU.
n By means of this the project engineering and programming hap-
pens.
n MPI serves for communication between several CPUs or between
HMIs and CPU.
n Standard setting is MPI Address 2.
8pin RJ45 jack:
n The RJ45 jack serves the interface to the Ethernet PG/OP
channel.
n This interface allows you to program res. remote control your
CPU, to access the internal web site or to connect a visualization.
n Configurable connections are not possible.
n For online access to the CPU via Ethernet PG/OP channel valid
IP address parameters have to be assigned to this.
