User-defined addressing
User-defined addressing means that you can assign an address of your choice to
any module (SM/FM/CP). The addresses are assigned in STEP 7. Here, you
specify the module start address that forms the basis for all other addresses of the
module.
Advantages of user-defined addressing:
• Optimization of the address areas available, since "address gaps" will not occur
between the modules.
• When creating standard software, you can program addresses which are
independent of the relevant S7-300 configuration.
