6. Review the Missed field in the I/O Packet Counter Statistics table.
This field shows how many I/O packets have been missed. Your
EtherNet/IP communication module may lose I/O packets due to
these conditions:
• Packets are produced faster than the connection’s requested packet
interval (RPI). This happens for change-of-state connections or a new
consumer requesting a faster RPI than the first consumer.
• A packet is received out of sequence.
Ethernet Statistics
The Ethernet Statistics web page presents the current configuration of an
EtherNet/IP communication module and any errors that have occurred on the
module.
IMPORTANT Because this example shows the diagnostic web pages for a 1756-EN2TR
module, diagnostic data is shown for two ports.
