Event log descriptions
Column title Description
Example
Received
Time Displays the date and time that the LAN
trigger occurred in UTC, 24-hour time 06:56:28.000 8 May 2011
Event ID Identifies the
lan.trigger[ N ]
that
generates an event
LAN0 = lan.trigger[1]
LAN1 = lan.trigger[2]
LAN2 = lan.trigger[3]
LAN3 = lan.trigger[4]
LAN4 = lan.trigger[5]
LAN5 = lan.trigger[6]
LAN6 = lan.trigger[7]
LAN7 = lan.trigger[8]
From Displays the IP address for the device that
generates the LAN trigger localhost
192.168.5.20
Timestamp
The Series 2600B does not support the
IEEE Std 1588 standard; the values in this
field are always 0 (zero)
HWDetect Identifies a valid LXI trigger packet LXI
Sequence Each instrument maintains independent
sequence counters:
•
One for each combination of UDP multicast
network interface and UDP multicast
destination port
•
One for each TCP connection
Domain Displays the LXI domain number; the default
value is 0 (zero) 0
1523
Flags Contain data about the LXI trigger packet;
values are:
•
1 - Error
•
2 - Retransmission
•
4 - Hardware
•
8 - Acknowledgments
•
16 - Stateless bit
Data The values for this are always 0 (zero)
Accessing the event log from the command interface
You can access the event log from any remote command interface. The event log must be enabled
before LXI trigger events can be viewed. To enable the event log, send:
eventlog.enable = 1
To view the event log from a remote interface, send:
print(eventlog.all())
