Address Space - Siemens S7-1500 Manual

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.
The letters "a" and "b" are printed on the module. "IB a" for example, stands for module start
address input byte a.
Configuration options of DI 16x24...125VUC 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:
Table 4- 2 Configuration options
Configuration
1 x 16-channel without value sta-
tus
1 x 16-channel with value status
2 x 8-channel without value status
2 x 8-channel with value status
1 x 16-channel with value status
for module-internal shared input
with up to 4 submodules
Value status (Quality Information, QI)
The value status is always activated for the following module names:
● DI 16x24...125VUC HF QI,
● DI 16x24...125VUC HF S QI
● DI 16x24...125VUC HF MSI
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).
