Unlike the 1 x 16-channel module configuration, each of the two submodules has a freely
assignable start address.
Figure 4-2 Address space for configuration as 2 x 8-channel DQ 16x230VAC/1A ST SIf the system is in shared device mode and one of the associated IO controllers goes into
STOP or fails due to, for example, a communication failure, all submodules of the output
module follow the configured substitute value behavior (e.g. switch off).
This means that even when only one IO controller fails, the other IO controllers associated
with the shared device no longer control the assigned submodule of the output moduFor the configuration as a 1 x 16-channel module (module-internal Shared Output, MSO),
channels 0 to 15 of the module are copied to multiple submodules. Channels 0 to 15 are
then available with identical values in various submodules. These submodules can be
assigned to up to four IO controllers when the module is used in a shared device:
● The IO controller to which submodule 1 is assigned has write access to outputs 0 to 15.
● The IO controllers to which submodule 2, 3, or 4 is assigned have read access to outputs
0 to 15.
The number of IO controllers depends on the interface module being used. Observe the
information in the manual for the particular interface module.
The meaning of the value status depends on the submodule on which it occurs.
For the first submodule (=basic submodule), the value status 0 indicates that the value is
incorrect or that the IO controller of the basic submodule is in STOP state.
For the 2nd to 4th submodule (=MSO submodule), the value status 0 indicates that the value
is incorrect or one of the following errors has occurred:
● The basic submodule is not yet configured (not ready).
● The connection between the IO controller and the basic submodule has been interrupted.
● The IO controller of the basic submodule is in STOP or POWER OFF state.The figure below shows the assignment of the address space for submodules 1 and 2 and
the value status.Address space for configuration as 1 x 16-channel DQ 16x230VAC/1A ST MSO with

Reference

You will find information on the module-internal shared input/shared output (MSI/MSO)
function in the function manual PROFINET with STEP 7 V13in the section Moduleinternal
shared input/shared output (MSI/MSO).The figure below shows the LED displays (status and error displays) of
DQ 16x230VAC/1A ST.oltage missing or too low at backplane bus • Switch on the CPU and/or the system
power supply modules.
• Verify that the U connectors are inserted.
• Check whether too many modules are
inserted.
