Address space for configuration as 2 x 8-channel DI 16x24VDC HF QI S
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 submodules is dependent on the interface module used. 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.
