86 Function Description
7.7.1.2

Virtual Option Modules

Are there obsolete I/O modules in a configuration variation, which are located
next to the end module, they can be omitted if at least one active spacer module is
part of the arrangement. In this use case the 2-channel analog output module
750-550 at slot 10, the 2-channel analog input module 750-467 at slot 11 as well
as the 2-channel relay output module 750-517 at slot 12 are not required. To
enable the extenuated configuration check of the fieldbus coupler the I/O module
at slot 10 has to be represented by an active spacer module. The I/O modules
located at slot 11 and 12 can be omitted and are processed as virtual.

7.7.1.3

Combination of Physical and Virtual Option Modules

This use case excludes the PROFIsafe V2 module 750-662/000-003 at slot 7 and
the 2-channel relay output module 750-517 at slot 12. The PROFIsafe V2 module
is represented by a physical option module. The I/O module at slot 12 can be
considered as virtual and thus be omitted because it is located next to the end
module and the extenuated configuration check is already enabled by the active
spacer module at slot 7.
