Port statistics
Proceed as follows to display the port statistics for an Ethernet port in STEP 7 HW Con-
fig:
1. Click the "ONLINE
→
OFFLINE", to switch to the "Online" communication mode.
2. Select a unit.
3. Select the desired port on slot 0.
4. Right-click on the port and select "Module status" from the context menu.
The "Module status ..." window is displayed.
Select the "Statistics" tab [1].
The following statistic values can be displayed:
•
Dropped received packets – no resources
Shows the number of valid Ethernet packets dropped upon reception. A large num-
ber of dropped valid packets suggests a high load on the bus system. In this case,
try to reduce the utilization by especially reducing the number of broadcast and mul-
ticast telegrams and reducing the IO cycle or the number of PROFINET units in a line
if required.
•
Bad received packets
Shows the number of faulty Ethernet packets. A high number suggests a bus error.
In this case, check the cabling and shielding of the network.
•
Received octets
Shows the number of received packets.
