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 inputs.
The letters "a to d" are printed onto the module. "EB a" for example, stands for module start
address input byte a.
Configuration options of DI 32x24VDC HF
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:

Value status (Quality Information, QI)
The value status is always activated for the following module names:
DI 32x24VDC HF QI
DI 32x24VDC HF S QI
DI 32x24VDC HF MSI
DI 32x24VDC HF Count
An additional bit is assigned to each channel for the value status. The value status bit
indicates if the read in digital value is valid. (0 = value is incorrect).
