(PROFINET IO only)
Value status (Quality Information, QI)
The value status is always activated for the DI 16x24VDC SRC 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.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.
The letters "a to d" are printed on the module - "EB a", for example, stands for module start
address input byte a.

Address space for configuration as 2 x 8-channel DI 16x24VDC SRC 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.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 2You can find information on the module-internal shared input/shared output (MSI/MSO)
