Parameters/address space
4.4 Address space
Address space for configuration as 8 x 1-channel AI 8xU/I HS QI and AI 8xU/I HS S QI
For the configuration as a 8 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 submodules is dependent on the interface module used. Observe the
information in the manual for the particular interface module.
Contrary to the 1 x 8-channel module configuration, each of the eight submodules has a
freely assignable start address.
