Address space for configuration as 1 x 8-channel AI 8xU/I HF MSI
The channels 0 to 7 of the module are copied in up to four submodules with configuration 1 x
8-channel module (Module-internal shared input, MSI). Channels 0 to 7 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 IO controllers depends on the interface module 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 1st submodule (= basic submodule), the value status 0 indicates that the value is
incorrect.
For the 2nd to 4th submodule (=MSI submodule), the value status 0 indicates that the value
is incorrect or the basic submodule has not yet been configured (not ready).
