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).
