value 1 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
outputs/inputs.
Configuration options of DQ 32x24VDC/0.5A 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 abbreviations/module names.
The following configurations are possible: x 32-channel without value status DQ 32x24VDC/0.5A ST V12 or higher X
1 x 32-channel with value status DQ 32x24VDC/0.5A ST

Value status (Quality Information, QI)
The value status is always activated for the following module names:
● DQ 32x24VDC/0.5A ST QI
● DQ 32x24VDC/0.5A ST S QI
● DQ 32x24VDC/0.5A ST MSO
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). The following figure shows the assignment of the address space for the configuration as a
32-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 onto the module. "For example, AB a" stands for module start
address output byte a.multiple submodules. The submodules can be assigned to different IO controllers when the
module is used in a shared device.
The number of usable submodules is dependent on the interface module used. Please
observe the information in the manual for the particular interface module.
Contrary to the 1 x 32-channel module configuration, each of the four submodules has a
freely assignable start address. The addresses for the respective value status of a
submodule can also be assigned by the user. Address space for configuration as 4 x 8-channel DQ 32x24VDC/0.5A ST S QI with value
statusFor the configuration as a 1 x 32-channel module (module-internal Shared Output, MSO),
channels 0 to 31 of the module are copied to multiple submodules. Channels 0 to 31 are
then available with identical values in various submodules. These submodules can be
assigned to up to four IO controllers when the module is used in a shared device:
● The IO controller to which submodule 1 is assigned has write access to outputs 0 to 31.
● The IO controllers to which submodule 2, 3, or 4 is assigned have read access to outputs
0 to 31.
The number of usable submodules is dependent on the interface module used. Observe the
information in the manual for the particular interface module.
Value status (Quality Information, QI)
The meaning of the value status depends on the submodule on which it occurs.
For the first submodule (=basic submodule), the value status 0 indicates that the value is
incorrect or that the IO controller of the basic submodule is in STOP state.
For the 2nd to 4th submodule (=MSO submodule), the value status 0 indicates that the value
is incorrect or one of the following errors has occurred:
● The basic submodule is not yet configured (not ready).
● The connection between the IO controller and the basic submodule has been interrupted.
● The IO controller of the basic submodule is in STOP or POWER OFF state.Figure 4-4 Address space for configuration as 1 x 32-channel DQ 32x24VDC/0.5A ST S MSO with
value statusThe following figure shows you the LED displays (status and error displays) of
DQ 32x24VDC/0.5A ST.
The following tables explain the meaning of the status and error displays. Remedial
measures for diagnostic reports can be found in chapter Diagnostics alarms (Page 23).

Voltage missing or too low at backplane bus • Switch on the CPU and/or the system power
supply modules.
• Verify that the U connectors are inserted.
• Check to see if too many modules are inserted.
Flashes Off
The module starts and flashes until the valid
parameter assignment is set.

one channel, e.g., short-circuit to ground).
Evaluate the diagnostics data and eliminate the
error (e.g., check the cables).
