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 calculated 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
