Hardware identifier
STEP 7 automatically assigns a hardware identifier to identify and address modules and
submodules. You use the hardware identifier in the case of diagnostic messages or
operations, for example, to identify a defective module or the module addressed.
Figure 7-6 Example of a hardware identifier from STEP 7
In the "System constants" tab, you will find all hardware identifiers and their symbolic names
(of the hardware identifier) for the selected module.
You can also find the hardware identifiers and names for all modules of a device in the
default tag table of the "System constants" tab.
