TCP: keepalive
Keepalive check cycle.
TCP: connects
Total number of connections established.
TCP: closed
Total number of closed connections.
TCP: timeoutdrop
Total number of dropped connections due
to TCP retransmission timeout. When the
transmitted packet is not received, the
MV retransmits the packet at given time
intervals. If the packet is not received after 14
retransmissions, a timeout occurs, and the MV
drops the connection.
TCP: keepdrops
Total number of dropped connections due to
TCP keepalive timeout.
TCP: sndtotal
Total number of sent packets.
TCP: sndbyte
Total number of sent bytes.
TCP: sndrexmitpack
Total number of retransmitted packets.
TCP: sndrexmitbyte
Total number of retransmitted bytes.
TCP: rcvtotal
Total number of received packets.
TCP: rcvbyte
Total number of received bytes.
DLC: 16 collisions
Number of collision incidents. A collision occurs
when two or more instruments on the network
attempt to transmit a packet simultaneously.
The tendency for collisions to occur increases
when the network is congested. “16 collisions”
refer to 16 consecutive collision incidents.
quit Disconnects the connection
to the instrument that is being
controlled
