You may access the modules with read res. write accesses to the
peripheral bytes or the process image.
To define addresses a hardware configuration may be used. For this, click
on the properties of the according module and set the wanted address.
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 bus.
Depending on the slot location the start address from where on the
according module is stored in the address range is calculated with the
following formulas:
DIOs:
Start address = 4
⋅
(slot -4)
AIOs, FMs, CPs:
Start address = 16
⋅
(slot -4)+256
