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 connected modules.
n
The power supply is protected against polarity inversion and overcurrent.
n
The internal electronic is galvanically connected with the supply voltage.
9pin SubD jack:
n
The MPI interface serves for the connection between programming unit and CPU.
n
By means of this the project engineering and programming happens.
n
MPI serves for communication between several CPUs or between HMIs and CPU.
n
Standard setting is MPI Address 2.
9pin SubD jack:
The CPU has a PtP interface. The interface is fix set to PtP communication.
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 PtP communication is configured during run-time by means of the SFC 216
(SER_CFG). The communication happens by means of the SFC 217 (SER_SND)
and SFC 218 (SER_RCV).
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 parame-
ters have to be assigned to this.
