5.10 Standard machine projects
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.
① Load configuration with multiple use IO system
② Set IP address and device name locally on the IO controller
Figure 5-92 "Multiple use IO system" principle
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.
Requirements
• 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.
