Example of Packaging Digital Information
In addition to the fieldbus coupler (DAP), a station consists of the following I/O
modules in the order shown:

The digital submodule at slot 1 allocates a total of 2 bytes in the input process
image and occupies 2 bits of that.
The digital submodule at slot 2 allocates a total of 2 bytes in the output process
image and occupies 4 bits of that.
There is an analog output submodule at slot 3 that plays no role in packaging
digital I/O modules.
The digital submodule at slot 4 requires 8 bits that are included in the output data
area allocated from slot 2. 4 bits of slot 2 are still available for additional output
data.
The digital submodule at slot 5 requires 4 bits that are included in the input data
area allocated by slot 1. 10 bits are still available from slot 1 for additional input
data.
The digital submodule at slot 6 allocates an additional output data area of 1 byte.
The area of slot 2 is closed and remains unused. The free bits do not reach the
peripherals.
The figures below show the packaged user data in the real-time PROFINET IO
telegram each in the output and input direction.
