the information in the manual for the particular interface module.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.You can find information on the module-internal shared input/shared output (MSI/MSO)
function in the section Module-internal shared input/shared output (MSI/MSO) of the function
manual PROFINET with STEP 7 V13The figure below shows the LED displays (status and error displays) of the
DI 16x230VAC BA.The following table explains the meaning of the status and error displays.

This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
