Module Status Information
Purpose
The partial list with SSL-ID W#16#xy96 contains status information on all the
modules assigned to the CPU.
The information in the partial list with SSL-ID W#16#xy96 supplements SSL-ID
W#16#xy91 and provides additional status data on submodules and interface
modules.
It provides information specific to PROFINET IO as well as information on
PROFIBUS DP modules and central modules.
Header
The header of the partial list with SSL-ID W#16#xy96 has the following structure:
