• Dropped sent packets – no resource
Shows the number of valid Ethernet packets dropped during transmission. A large
number 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
multicast telegrams and reducing the IO cycle or the number of PROFINET units in
a line if required.
• Bad sent packets – transmit collisions
Shows the number of Ethernet packets dropped due to collisions. There should be
no collisions in a switched network.
• Sent Octets
Shows the number of transmitted packets.
