Configuring PROFINET IO Devices
The following table shows what information is displayed in the "Object Name"
column:
Accessible Nodes is... Displayed in the "Object
Name ,,," column
PROFINET IO device with assigned
device name
PROFINET IO device without
assigned device name
Explanation
Device name IP address and MAC address can
be determined in a properties
dialog. The "Details" view also
shows the device type as well as
status information (e.g. IP
addresses inadvertently assigned
twice ("doubled-up"), errors, etc.).
IP address As a substitute (for an unassigned
IP address) the MAC address is
displayed.
S7 CP Name (of the station) Only if an IP address was
assigned to the CP; otherwise,
MAC address. The "Details" view
also shows the operating mode
and the module type.
S7 CPU, PC stations Name (of the station) The "Details" view also shows the
operating mode and the module
type, and, if available, information
from the associated STEP 7
project (station name, CPU name,
plant designation).
IE/PB link See PROFINET device Special issue: if you select the
IE/PB link in the "Accessible
Nodes" list, the detailed list then
displays the connected DP slaves
along with their PROFIBUS
addresses as well as other
information.
Other nodes (no S7 nodes or
devices with DCP protocol)
---- Cannot be displayed
Calling diagnostic functions
You can perform system diagnostics from the "Accessible Nodes" window. To do
so, proceed as follows:
1. Select the component to be diagnosed.
2. Select the appropriate menu command (menu: PLC > Diagnostics/Settings >
...).
As of STEP 7 V5.3 Service Pack 2, the "Module Information" diagnostic function
can also be used for DP slaves "behind" the IE/PB link; that is, for those devices
that are not directly connected to the Ethernet.
