Address space for configuration as 4 x 8-channel DQ 32x24VDC/0.5A HF S QI
For the configuration as a 4 x 8-channel module, the channels of the module are divided into
multiple submodules. The submodules can be assigned to different IO controllers when the
module is used in a shared device.
The number of IO controllers depends on the interface module used. Please observe the
information in the manual for the particular interface module.
Contrary to the 1 x 32-channel module configuration, each of the four submodules has a
freely assignable start address. The addresses for the respective value status of a
submodule can also be assigned by the user.

Address space for configuration as 1 x 32-channel DQ 32x24VDC/0.5A HF MSO
For the configuration as a 1 x 32-channel module (module-internal Shared Output, MSO),
channels 0 to 31 of the module are copied to multiple submodules. Channels 0 to 31 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 31.
● The IO controllers to which submodule 2, 3, or 4 is assigned have read access to outputs
0 to 31.
The number of IO controllers depends on the interface module used. Observe the
information in the manual for the particular interface module.
