You can find the TIA Selection Tool on the The module has the following technical properties:
● 16 digital outputs (Triac)
● Rated output voltage 120 V/230 V AC
● Rated output current 1A (per channel)
● Configurable substitute values (per channel)
● Suitable for solenoid valves, DC contactors, indicator lights and smaller single phase
drivesThe following components are supplied with the module and can also be ordered separately
as spare parts:
● Labeling strips
● U connector
● Universal front door
Other components
The following component must be ordered separately:
Front connectors, including potential jumpers and cable ties
For more information on accessories, refer to the , ET 200MP system manual This section contains the block diagram of the module and outlines various wiring options.
You will find information on wiring the front connector, establishing a cable shield, etc in the
system manual /ET 200MP Do not insert the potential jumpers included with the front connector!The example in the following figure shows the terminal assignment and the assignment of
the channels. The individual channels are connected with a TRIAC (Triode for Alternating
Current).Determines the reaction of the output to the CPU going into STOP state or when the
connection to the CPU is interrupted.
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 output/input.
Configuration options of DQ 16x230VAC/1A ST
You can configure the module with STEP 7 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:

Value status (Quality Information, QI)

The value status is always activated for the DQ 16x230VAC/1A 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 figure below shows the address space allocation for the configuration as 16-channel
module. 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 b" are printed onto the module. "For example, AB a" stands for module start
address output byte a.If the system is in shared device mode and one of the associated IO controllers goes into
STOP or fails due to, for example, a communication failure, all submodules of the output
module follow the configured substitute value behavior (e.g. switch off).
This means that even when only one IO controller fails, the other IO controllers associated
with the shared device no longer control the assigned submodule of the output module.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.You will find information on the module-internal shared input/shared output (MSI/MSO)
function in the function manual PROFINET with STEP 7 V13 The figure below shows the LED displays (status and error displays) of
DQ 16x230VAC/1A ST.The following table explains the meaning of the status and error displays.Switch on the CPU and/or the system
power supply modules.
• Verify that the U connectors are inserted.
• Check whether too many modules are
