Addresses of digital modules
The address of an input or output of a digital module is made up of the byte address and the bit
address.
Figure 7-2
The byte address is governed by the module start address.
You can note the bit address on the module.
The figure below shows you the scheme by which the addresses of the individual channels of the
digital module are obtained.
Figure 7-3
Example of digital modules
The example in the figure below shows which default addresses are derived when a digital
module is located in slot 4 (that is, when the module start address is 0).
Slot number 3 is reserved as no interconnection module is present in the example.
