In contrast to the ADAM Profibus slave IM 8253DP, the Profibus coupler in
the CPU 821xDP is an "intelligent coupler".
The "intelligent coupler" processes data that is available from an input or an
output area of the CPU. This area and an area for status and diagnostic
data are fixed via the CPU 821xDP properties. Separate memory areas are
used for input and for output data. Those areas are to handle with your PLC
program.
Due to the system, the address areas occupied by the coupler are not
displayed in the hardware configurator from Siemens. For the directly
plugged-in System 82xx modules are also included in the periphery
address range, there may occur address overlappings during the automatic
address allocation.
Note!
For configuring the CPU and the Profibus-DP master a thorough knowledge

of the STEP 7 manager and the hardware configurator from Siemens is
required!
The address allocation and the parameterization of the directly plugged-in
System 82xx modules takes place via the STEP
in form of a virtual Profibus system.
For the Profibus interface is software standardized, ADAM is able to
guarantee the availability of the complete functions of the System 82xx
modules by including the GSD-file in the manager.
To be compatible with the STEP
to execute the following steps:
• Project the CPU 315-2DP with DP master system (address 2).
• Add Profibus slave "DP8000" with address 1.
• Include the CPU type 821xDP at plug-in location 0 of the slave system.
• Adjust the Profibus parameters of the CPU 821xDP.
• Include directly plugged-in periphery modules at the plug-in locations
1...32.
• Transfer project via MPI into the CPU 821xDP
• Project CPU with DP master system (address 2).
• Add Profibus slave 821xDP (GSD-file required).
• Fix the Profibus input and output areas starting with plug-in location 0.
