I/O Addresses Of An Analog Module In Slot 4 - Siemens CPU 313C Hardware And Installation Manual

$GGUHVVLQJ
$Q H[DPSOH IRU DQDORJ PRGXOHV
The example in the figure below shows you which default channel addresses are
obtained if an analog module is inserted in slot 4. As you can see, the input and
output channels of an analog I/O module are addressed starting at the same
address, namely the module start address.
Slot number 3 has not been assigned since there is no interface module in the
example.
