Address space for configuration as 1 x 9-channel AI 8xU/R/RTD/TC HF MSI
The channels 0 to 8 of the module are copied in up to 4 submodules for the configuration as
1 x 9-channel module (module-internal shared input, MSI). Channels 0 to 8 are then
available with identical input values in various 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 usable submodules is dependent 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).
