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 output/input.
Configuration options of DQ 8x230VAC/2A 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 short designations/module names.
The following configurations are possible:
Table 4- 2 Configuration options
Configuration
1 x 8-channel without value status
1 x 8-channel with value status for mod-
ule-internal Shared Output with up to 4
submodules
Value status (Quality Information, QI)
The value status is always activated for the DQ 8x230VAC/2A ST MSO module.
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).
Address space for configuration as 8-channel DQ 8x230VAC/2A ST
The following figure shows the assignment of the address space for the configuration as a
8-channel module with value status. You can freely assign the start address for the module.
The addresses of the channels are derived from the start address.
The letters "a to d" are printed on the module; "QB a", for example, stands for module start
address output byte a.
