Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit
(http://www.siemens.com/industrialsecurity).
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed under (http://www.siemens.com/industrialsecurity).

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 of the inputs.
The letters "a to d" are printed on the module - "EB a", for example, stands for module start
address input byte a.
Configuration options of DI 16x230VAC 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.

Value status (Quality Information, QI)
The value status is always activated for the DI 16x230VAC BA MSI module.
An additional bit is assigned to each channel for the value status. In contrast to the modules
with diagnostics capability, the module only shows information regarding the parameter
assignment of the first submodule (basic submodule) in the value status.
The module does not supply a value status for the read-in digital value.

Manual, 09/2016, A5E03485975-AD 15
Address space for configuration as DI 16x230VAC BA
The following figure 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.
Figure 4-1 Address space for configuration as 16-channel DI 16x230VAC BA
Address space for configuration as 2 x 8-channel DI 16x230VAC BA S
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 IO controllers depends on the interface module used. Please observe
the information in the manual for the particular interface module.
Contrary to the 1 x 16-channel module configuration, each of the two submodules has a
freely assignable start address.
Figure 4-2 Address space for configuration as 2 x 8-channel DI 16x24VDC SRC BA S
Address space for configuration as 1 x 16-channel DI 16x230VAC BA MSI
The channels 0 to 15 of the module are copied in up to four submodules with configuration
1 x 16-channel module (Module-internal shared input, MSI). Channels 0 to 15 are then
available with identical input values in different submodules. These submodules can be
assigned to up to four IO controllers when the module is used in a shared device. Each
IO controller has read access to the same channels.
The number of usable IO controllers depends on the interface module used. Please 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 involved.
For the 1st submodule (=basic submodule), the value status is not relevant.
For the 2nd to 4th submodule (=MSI submodule), the value status 0 indicates that the basic
submodule parameters have not yet been assigned (not ready).
The figure below shows the assignment of the address space with submodules 1 and 2.
