32 inputs 0 to 31
32 inputs 32 to 63
32 outputs 0 to 31
This results in the following address space:
1. Input range
Input byte (chain number *32) to (chain number *32) +7, i.e. from input byte
32 to input byte 39 for operation in chain 1
2. Output range
Output byte (chain number *32) +8 to (chain number *32) +11, i.e. from out-
put byte 40 to output byte 44 for operation in chain 1
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.
