CPU 21xDP configuration
In contrast to the VIPA Profibus slave IM 253DP, the Profibus coupler in
the CPU 21xDP 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 21xDP 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 200V 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 know-
ledge of the SIMATIC manager and the hardware configurator from Sie-
mens is required!
The address allocation and the parameterization of the directly plugged-in
System 200V modules takes place via the SIMATIC manager from
Siemens in form of a virtual Profibus system.
For the Profibus interface is software standardized, VIPA is able to
guarantee the availability of the complete functions of the System 200V
modules by including the GSD-file vipa_21x.gsd in the manager.
To be compatible with the SIMATIC manager from Siemens, you have to
execute the following steps:
• Project the CPU 315-2DP with DP master system (address 2).
• Add the Profibus slave "VIPA_CPU21x" from the VIPA_21x.gsd with
address 1.
• Include the CPU type 21xDP at the 1
st
slot of the slave system.
• Adjust the Profibus parameters of the CPU 21xDP.
• Include directly plugged-in periphery modules at the following slots.
• Transfer project via MPI into the CPU 21xDP
• Project CPU with DP master system (address 2).
• Add the Profibus slave "VIPA_CPU2xxDP" from the VIPA04D5.gsd.
• Set the Profibus in- and output ranges starting with the 1
st
slot. Please
regard that the length settings at the slave must be congruent to the
Byte settings in the master!
