Address space of the analog on-board I/O
Address space of the analog input and output channels
The addresses are divided into five analog input channels and two analog output channels.
STEP 7 (TIA Portal) assigns the addresses automatically. You can change the addresses in
the hardware configuration of STEP 7 (TIA Portal), i.e. freely assign the start address. The
addresses of the channels are based on the start address.
"IB x" stands, for example, for the start address input byte x. "QB x" stands, for example, for
the start address output byte x.
