Address space for configuration as 4 x 8-channel DI 32x24VDC HF S QI
For the configuration as a 4 x 8-channel module, the channels of the module are divided into
four submodules. The submodules can be assigned to different IO controllers when the
module is used in a shared device.
The number of I/O controllers depends on the interface module being used. 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 channels 0 to 31 of the module are copied in up to four submodules with configuration 1
x 32-channel module (Module-internal shared input, MSI). Channels 0 to 31 are then
available with identical input values in different submodules. These submodules can be
assigned to up to four IO controllers when the module is used in a shared device. Each IO
controller has read access to the same channels.
The number of I/O controllers depends on the interface module being used. Please observe
the information in the manual for the particular interface module.
Value status (Quality Information, QI)
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.
