First click on the symbol in front of the entry "DC532" and then click on this symbol in front of the entry
"Digital Inputs 0-15[FIX]
". The I/O address mapping in the CPU is displayed:
In our example, it is possible to access the digital inputs of the DC532 module as word using the address
%IW0 (simultaneous access to the 16 inputs I0…I15) or as bytes (inputs 0 - 7 using the address %IB0,
inputs I8 - I15 using the address %IB1) or as individual bits (addresses %IX0.0 to %IX0.7 for inputs I0 -
I7 or %IX1.0 to %IX1.7 for the inputs I8 - I15).
ATTENTION
In our example, the DC532 I/O expansion module used has digital inputs
and also digital configurable inputs/outputs. These configurable I/Os are
displayed in the I/O mapping either as inputs or as outputs according to
how the channel will be used by the user!
