Total number of disconnection on port 34150 due to timeouts
Total number of disconnection on port 34151 due to timeouts
Keep alive chack sycle
Total number of times the connection has been disconnected
Total number of times the connection has been disconnected due to TCP retransmission * 1
Total number of times the connection has been disconnected due to TCP Keepalive timeouts
Total number of packets * 2 transmitted
Total number of bytes transmitted
Total number of packets retransmitted
Total number of bytes retransmitted
Total number of packets received
Total number of bytes received
Number of times 16 collision* 3 occurred
*1: If the sent packet is not received, the packet is automatically retransmitted at a predetermined time
interval. If the packet is not received after retransmitting 14 times from the DR, the connection is
disconnected as a timeout.
*2: The unit (size) by which data are transmitted.
*3: Collisions occur when packets collide on the network. Collisions occur more frequently when the
network is congested. The condition in which collisions occur 16 times in succession is called 16
Timeout setting (ET command)
Total number of times the connection has been established
