You can find the My Documentation Manager on the Internet Applications & Tools supports you with various tools and examples for solving your
automation tasks. Solutions are shown in interplay with multiple components in the system -
separated from the focus in individual products.

You can configure the module with STEP 7 (TIA Portal) and with a GSD file.
Accessories
The following accessories are supplied with the module and can also be ordered separately
as spare parts:
● Labeling strips
● U connector
● Universal front doorThe following component must be ordered separately:
Front connectors, including potential jumpers and cable ties
You can find more information on accessories in the Automation System This section contains the block diagram of the module and outlines various connection
options.
For more information on front connector wiring and creating cable shields, for example, refer
to the "Wiring" section in the Automation System Meaning of the abbreviations used in the following figures:
xL+ Supply voltage connection
xM Ground connection
CHx Channel or display of the channel status
PWRx Display for the supply voltage (POWER).5 ST parameters
When you assign the module parameters in STEP 7, you use various parameters to specify

the module properties. The following table lists the configurable parameters. The effective
range of the configurable parameters depends on the type of configuration. The following
configurations are possible:
● Central operation with a CPU
● Distributed operation on PROFINET IO in an ET 200MP system
● Distributed operation on PROFIBUS DP in an ET 200MP system
For parameter assignment in the user program, the parameters are transferred to the
module using the WRREC instruction (parameter reassignment in RUN) and data records;
see chapter Parameter assignment and structure of the parameter data records (Page 30).
Table 4- 1 Configurable parameters and their defaultsAddress 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
outputs/inputs.
Configuration options of DQ 16x24VDC/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 possibleThe value status is always activated for the following module names:
● DQ 16x24VDC/0.5A ST QI
● DQ 16x24VDC/0.5A ST S QI
● DQ 16x24VDC/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).
Special characteristics of short-circuit to ground
If a channel is short-circuited, all bits of the corresponding value status input byte are set to
0. The module signals all channels of the relevant byte as faulty.The following figure shows the assignment of the address space for the configuration as a
16-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
