Siemens SINAMICS DCM Manual page 632

Sample calculation:
The SINAMICS DM is equipped with one AOP30 and two TM31 modules. The DCC diagram
is to be computed on the DO DC_CTRL.
→ 600 – 200 – 2×150 = 100 DCC blocks can be computed on the DO DC_CTRL.
Notes:
● If there is insufficient memory on the CUD for the configuration of the desired DCC
diagram, the scope of the blocks needs to be reduced or the SINAMICS DCM needs to
be equipped with a 2nd CUD on the right-hand slot.
● The computation rules stated above also apply to the CUD on the right-hand slot.
● In most cases, the CPU time load of the CUD becomes the limiting factor when designing
the DCC application and not the memory load.
10.36.4 Backing up the DCC diagrams
A DCC project comprises two parts.
1. Information about the type, time slices and interconnection of the DCB blocks
2. Information about the layout and graphics in the DCC charts
When downloading the DCC chart to the drive (download to the target system), only the
information about the type, time slices and interconnection of the DCB blocks (Point 1) are
downloaded to the drive.
If required, the DCC charts can also be saved in the target device. A further prompt appears
after selecting the "Download to Target System" window. The DCC charts are also saved
when both checkboxes are activated.
The following prompt appears when selecting "Load to PG" later:
