The following figure shows how an automation solution with a multiple use IO system is
loaded on different automation systems and then one automation system is adapted to the
existing network infrastructure locally.
Load configuration with multiple use IO system
Set IP address and device name locally on the IO controller
Figure 5-76 "Multiple use IO system" principle
The automation components for a machine include a PROFINET IO system, consisting of an
IO controller (PROFINET interface of a CPU) and the IO devices assigned to it.
With the "Multiple use IO system" setting for the IO system, you turn a STEP 7 project into a
"Standard machine project".
The "Multiple use IO system" setting triggers various settings and checks of the configuration
by STEP 7. The settings ensure that the IO system is self-contained and there are no
dependencies on components outside the IO system.
● STEP 7 as of V13
● The IO controller supports the "Multiple use IO system" function, for example a CPU
1512SP-1 PN as of firmware version 1.6.
