Address space DI mode

Address space for configuration as 16-channel DI 16x24VDC HF QI
The figure below shows the assignment of the address space for the configuration as a
16-channel module with value status. You can freely assign the start address for the module.
The addresses of the channels are derived from the start address.
Figure 4-1
Address space for configuration as 2 x 8-channel DI 16x24VDC HF S QI
For the configuration as a 2 x 8-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.
Contrary to the 1 x 16-channel module configuration, each of the two submodules has a
freely assignable start address.
