23.5.3 Scope of the Module Type-Dependent Information
The scope of information that can be evaluated and displayed is dependent on:
• The module selected, and
• From which view you call the module information
A full scope of information is available when called from the online view of the configuration
tables or from the project window.
A limited scope of information is available when called from the "Accessible Nodes" window.
Depending on the scope of the information, the modules are divided into the categories "with
system diagnostic capability," "with diagnostic capability," or "without diagnostic capability." The
following figure shows these categories:
• Modules with system diagnostic capability are, for example, the modules FM 351 and
FM 354
• Modules with diagnostic capability are most analog signal modules.
• Modules without diagnostic capability are most digital signal modules.
