5.9 Standard machine projects
PROFINET with STEP 7 V15
222 Function Manual, 12/2017, A5E03444486-AH
The configuration of a series machine using an S7-1500-CPU as an example is described
below.
To create a standard machine project, follow these steps:
1. Create a project.
2. Configure a CPU as the IO controller, for example a CPU 1518-4 PN/DP as of firmware
version 1.5.
3. Configure the required IO devices and assign the IO devices to the IO controller.
4. Configure the port interconnection between the devices.
5. Select the IO system so that you can edit the properties in the inspector window.
6. Select the "Multiple use IO system" check box in the "General" area of the inspector
window.
Figure 5-78 Activate "Multiple use IO system"
: The following settings are made by STEP 7:
● The device name of the IO controller (CPU) in the standard machine project is set to
"PROFINET device name is set directly at the device". The IO controller (CPU) has no
PROFINET device name initially.
● The IP protocol of the IO controller (CPU) is set to "IP address is set directly at the
device". The CPU has no IP address initially.
● The "Support device replacement without exchangeable medium" option is selected
automatically. This option enables automatic commissioning. A commissioning engineer
does not have to assign device names to the IO devices locally. The IO controller assigns
the device name and IP address to the IO devices based on the preset topology and
other settings during startup.
● The device name of the IO devices is set to "Generate PROFINET device name
automatically" (from the configured name of the IO device).
● The IP protocol of the IO devices is set to "IP address is set by the IO controller during
runtime". The IO devices have no IP address initially. If an IO device is not a typical
distributed I/O system (e.g., ET 200 systems), but rather another device such as an HMI
device, change the option to "IP address is set directly at the device"; see below.
● The device number for the IO devices is automatically assigned and is used locally for
making the IP address unique.
