5 I/O Modules
5.1 Single I/O module
This results in the following address space:
1. Input range
2. Output range
Only one I/O module is possible per chain.
The address range is assigned automatically during start-up. Parameterization
is not required.
In HW-Config, it is possible to treat the 840D I/Os as the equivalent arrange-
ment of S7-300 modules.
