System behavior and rules

Below, you find a description of how an IO system whose configuration is controlled by the
user program behaves in operation.
In addition, rules and restrictions are listed here which must be considered when configuring
the maximum structure of the configuration in a standard machine project.
System behavior
● System diagnostics:
If an optional IO device is deactivated, the IO device is displayed as "deactivated" from
the system diagnostics viewpoint (online view or Online & Diagnostics).
● Topology view:
Offline view: As configured. No interconnection is shown for ports with partner ports
configured as "Setting partner by user program".
Online view: Ports and interconnections with deactivated IO devices are shown in a
different shade of green as error-free ports and interconnections of activated IO devices.
● Representation in the Web server:
The names of devices are shown as configured (Properties > General > Project
information).
The assigned PROFINET device name for the CPU is shown on the "Communication"
website, at the "Parameter" tab.
IP address parameters: Currently assigned IP address parameters are shown on the site
"Module state".
Topology: The current topology resulting from any customizations via user program is
shown in the Web server. IO devices configured as optional are shown as "deactivated"
IO devices in the Web server.
