You may access the modules with read res. write accesses to the
peripheral bytes or the process image.
T
o define addresses a hardware configuration may be used. For this,
click on the properties of the according module and set the wanted
address.
CAUTION!
Please take care not to configure a double address
assignment at connection via external PROFIBUS DP
masters - required for project engineering of a SPEED-
Bus system! At external DP master systems, the Sie-
mens hardware configurator does not execute an
address check!
If you do not like to use a hardware configuration, an automatic
addressing comes into force. At the automatic address allocation
DIOs occupy depending on the slot location always 4byte and AIOs,
FMs, CPs always 16byte at the standard bus and 256byte at the
SPEED-Bus. Depending on the slot location the start address from
where on the according module is stored in the address range is cal-
culated with the following formulas:
Standard-Bus
n DIOs: Start address = 4×(slot-1)
n AIOs, FMs, CPs: Start address = 16×(slot-1)+256
SPEED-Bus
n DIOs: Start address = 4×(slot-101)+128
n AIOs, FMs, CPs: Start address = 256×(slot-101)+2048
