Data records 64 to 71 for channels 0 to 7 (submodule 1)
● Data records 64 to 71 for channels 8 to 15 (submodule 2)
Address the respective submodule for data record transferUpon activation of the 24 V supply voltage, there is a "1" signal at the module outputs for
approx. 50 μs.The module can be configured in various ways in STEP 7. Depending on the configuration,
additional/different addresses are assigned in the process image of the outputs/inputs.
Configuration options of DQ 16x24VDC/0.5A BA
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:The figure below shows the address space assignment for configuration as a 1 x 16-channel
module. You can freely assign the start address for the module. The addresses of the
channels are based on the start address.
The letters "a" to "d" are printed on the module. "AB a", for example, stands for module start
address output byte a.For the configuration as a 2 x 8-channel module, the channels of the module are divided into
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 depends on the interface module used. Please observe
the information in the manual for the particular interface module.
Unlike the 1 x 16-channel module configuration, each of the two submodules has a freely
assignable start address.For the configuration as a 1 x 16-channel module (module-internal Shared Output, MSO),
channels 0 to 15 of the module are copied to multiple submodules. Channels 0 to 16 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 15.
● The IO controllers to which submodules 2, 3 or 4 are assigned have write access to the
outputs 0 to 15.
The number of usable submodules depends on the interface module used. Please observe
the information in the manual for the particular interface moduleThe meaning of the value status depends on the submodule involved.
For the 1st submodule (=basic submodule), the value status 1 indicates that the output value
specified by the user program is actually output at the module terminal.

Possible causes for value status = 0:
● Value is incorrect, for example, because the supply voltage is missing.
● IO controller of the basic submodule is in STOP mode.
For the 2nd to 4th submodule (=MSO submodule), the value status 1 indicates that the
output value specified by the user program is actually output at the module terminal.
Possible causes for value status = 0:
● Value is incorrect, for example, because the supply voltage is missing.
● IO controller of the basic submodule is in STOP mode.
● The basic submodule is not yet configured.The figure below shows the assignment of the address space for submodules 1 and The figure below shows you the LED displays (status and error displays) of the
DQ 16x24VDC/0.5A BA.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.
