WAGO-I/O-System 750
750-370 PROFINET IO Fieldbus Coupler
• When assigning, only I/O modules with digital input and output data are
taken into account.
I/O modules with analog input/output data are ignored even when physically
between the digital input/output data according to the configuration.
• When assigning, I/O modules are ignored, for which an incorrect submodule
type has been configured, i.e. for which the submodule type does not match
the I/O module physically inserted.
Allocated areas that are not occupied are handled as followed by the fieldbus
coupler:
• Output data that has been allocated, but not occupied, is ignored by the
fieldbus coupler (DAP).
• Input data that has been allocated, but not occupied, is set to zero ("false")
by the fieldbus coupler (DAP).
7.6.1.2

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:

Table 35: Example for a Station with the Following Selected Submodules

Slot
0
1
2
3
4
5
6
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.
