* If you enable diagnostics for multiple channels, you will receive an alarm surge on failure of the supply voltage because
each enabled channel will detect this fault.
You can prevent this message burst by
assigning the diagnostics function to one channel only.
** The scope can be assigned for each channel during parameter assignment in RUN.
4.2
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. "IB a" for example, stands for module start
address input byte a.
Configuration options of DI 16x24VDC 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:
