Address space
The module can be configured differently in STEP 7; see following table. Depending on the
configuration, additional/different addresses are assigned in the process image of the
outputs/inputs.
The letters "a and b" are printed onto the module. "IB a" for example, stands for module start
address input byte a.
Configuration options of DQ 16x24...48VUC/125VDC/0.5A ST
You can configure the module with STEP 7 (TIA Portal) or with a GSD file.
When you configure the module by means of the GSD file, the configurations are available
under different abbreviations/module names.
The following configurations are possible:

Shared Output with up to
4 submodules
Value status (Quality Information, QI)
The value status is always activated for the following module names:
● DQ 16x24...48VUC/125VDC/0.5A ST QI
● DQ 16x24...48VUC/125VDC/0.5A ST S QI
● DQ 16x24...48VUC/125VDC/0.5A ST MSO
An additional bit is assigned to each channel for the value status. The bit for the value status
indicates if the output value specified by the user program is actually pending at the module
terminal (0 = value is incorrect).
