Parameters/address space
4.4 Address space
Address space for configuration as 4 x 1-channel AI 4xU/I/RTD/TC 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. Please 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.
Figure 4-5
Address space for configuration as 1 x 4-channel AI 4xU/I/RTD/TC ST MSI
The channels 0 to 3 of the module are copied in up to 4 submodules with configuration
1 x 4-channel module (Module-internal shared input, MSI). Channels 0 to 3 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 available submodules depends on the used interface module. Please
observe the information in the manual for the particular interface module.
