Address space for configuration as 4 x 1-channel AQ 4xU/I ST S QI
For the configuration as a 4 x 1-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 usable IO controllers depends on the interface module used. Observe the
information in the manual for the particular interface module.
Unlike the 1 x 4-channel module configuration, each of the four submodules has a freely
assignable start address.

Address space for configuration as 1 x 4-channel AQ 4xU/I ST MSO
For the configuration as a 1 x 4-channel module (module-internal Shared Output, MSO),
channels 0 to 3 of the module are copied to multiple submodules. Channels 0 to 3 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 3.
● The IO controllers to which submodule 2, 3, or 4 is assigned have read access to outputs
0 to 3.
The number of usable IO controllers depends on the interface module used. Please observe
the information in the manual for the particular interface module.
