Parameters/address space
4.3 Address space
Address space for configuration as 2 x 8-channel DQ 16x24VDC/0.5A 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 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. The addresses for the respective value status of a
submodule can also be assigned by the user.
Figure 4-2
Address space for configuration as 1 x 16-channel DQ 16x24VDC/0.5A HF MSO
For the configuration as a 1 x 16-channel module (module-internal shared output, MSO),
channels 0 to 15 of the module are copied to multiple submodules. Channels 0 to 15 are
then available with identical values in various submodules. These submodules can be
assigned to up to four IO controllers when the module is used in a shared device:
● The IO controller to which submodule 1 is assigned has write access to outputs 0 to 15.
● The IO controllers to which submodule 2, 3, or 4 is assigned have read access to outputs
0 to 15.
The number of IO controllers depends on the interface module used. Observe the
information in the manual for the particular interface module.
