4.3 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.
Configuration options of DI 8x24VDC ST
You can configure the module with STEP 7 (TIA Portal) or with a GSD file. If you configure
the module using a GSD file, the configurations are available under various short
designations/module names; see the table below. The following configurations are possible:

Evaluating the value status
An additional byte is allocated in the input address space if you enable the value status for
the digital module. Bits 0 to 7 in this byte are assigned to a channel. They provide
information about the validity of the digital value.
Bit = 1: No fault is present on the channel.
Bit = 0: Channel is disabled or there is a fault/error on the module.
If a fault/error occurs on a channel with this module, the value status for all channels is 0.
Address space
The following figure shows the assignment of the address space for the DI 8×24VDC ST with
value status (Quality Information (QI)). The addresses for the value status are only available
if the value status is enabled.
