Tab. 26: Static Input Assemblies, DeviceNet

The addresses indicated in “Tab. 26” can be used as a path
statement for the Produced Connection Path attribute of an
I/O connection.
This I/O connection can be used to transfer the attributes described
in more detail in the following “Tab. 27” as input process data.
Nevertheless, by using this address data, the attributes combined
in the assemblies can also be accessed acyclically at any time via
Explicit Messages.
