3.1 Slot-Oriented Addressing of the I/O Modules
Slot-Oriented Address Allocation
In slot-oriented addressing (default addressing) each slot number in a module is
allocated an address area in the IM 151-7 CPU.
Depending on the type of I/O module, the addresses are digital or analog (see
Table 3-1). The address allocation is not fixed and can be changed, but there is a
default address area.
