Configuring PROFINET IO Devices
4.4.2 Displaying Ethernet Nodes in the "Accessible Nodes" Window
Requirements
You have set up the programming device (PG)/PC interface to work with a TCP/IP
interface card, which means that the Ethernet interface of your programming
device (PG)/PC can be accessed from STEP 7.
For an online connection via the "Accessible Nodes" window, the programming
device (PG)/PC and "Accessible Nodes" must be connected to the same physical
Ethernet subnet.
If nodes are only accessible via intermediate switches or routers (with the use of a
protocol), they will not be displayed in the list of "Accessible Nodes".
Nodes displayed
The following components are shown in the "Accessible Nodes" window:
• S7-CPs
• S7-CPUs
• SIMATIC PC stations
• SIMATIC network components (PROFINET devices)
• All PROFINET devices (in general, all devices that support the DCP protocol)
• IE/PB link with its subordinate DP slaves
Depending on the type of component, there may be more less information
displayed in the detailed view of the "Accessible Nodes" window.
