Commissioning
• Install the CPU 21xDP.
• Configure the CPU 21xDP in your master system.
• Configure the I/O periphery that is connected to the backplane bus.
• Connect the CPU 21xDP to your Profibus.
• Turn on the power supply.
• Transfer your project to the CPUs.
Assemble the CPU 21xDP with the required peripheral modules. Do not
exceed the maximum current capacity of your power supply.
Note!
The bus cable has always to be terminated with the ripple resistor to avoid
reflections and therefore communication problems!
Configure your CPU 21xDP in your master system. You may use the VIPA
WinNCS package for this purpose. To configure the System 200V Profibus
slave modules from VIPA, you need to include the according GSD-file.
The System 200V peripheral modules that are connected with the CPU
21xDP directly via the backplane bus are automatically mapped into the CPU
address area. You may alter the address allocation in the hardware
configurator from Siemens at any time.
The CPU 21xDP has an integrated power supply that has to be provided
with DC 24V.
Via the voltage supply not only the CPU is provided with voltage but also
the bus coupler and, via the backplane bus, the peripheral modules. Please
regard, that the integrated power supply may provide the backplane bus
with max. 3A.
Profibus and backplane bus are galvanically separated from each other.
