The CPU has an integrated power supply:
n The power supply has to be provided with DC 24V. For this serves
the double DC 24V slot, that is underneath the flap.
n Via the power supply not only the internal electronic is provided
with voltage, but by means of the backplane bus also the con-
nected modules.
n The power supply is protected against polarity inversion and over-
current.
n The internal electronic is galvanically connected with the supply
voltage.
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.
9pin SubD jack:
The CPU has a PROFIBUS/PtP interface with a fix pinout. After an
overall reset the interface is deactivated. By appropriate configura-
tion, the following functions for this interface may be enabled:
n PROFIBUS DP master operation
–
Configuration via PROFIBUS sub module X1 (MPI/DP) with
‘Operation mode’ master in the hardware configuration.
n PROFIBUS DP slave operation
– Configuration via PROFIBUS sub module X1 (MPI/DP) with
‘Operation mode’ slave in the hardware configuration.
n PtP functionality
– Using the PtP functionality the RS485 interface is allowed to
connect via serial point-to-point connection to different source
res. target systems.
– Here the following protocols are supported: ASCII, STX/ETX,
3964R, USS and Modbus-Master (ASCII, RTU).
– The activation of the PtP functionality happens by embedding
the SPEEDBUS.GSD from VIPA in the hardware catalog. After
the installation the CPU may be configured in a PROFIBUS
master system and here the interface may be switched to PtP
communication.
