The default setting is to capture all traffic. These can be used to determine worst case device performance. Statistics files are named using the same name as your capture file and a file extension of “. This type of filtering eliminates capturing unnecessary frames and allows the user to quickly pin-point the source of the network problem. The device IDs are octal numbers running from a value of to octal.

It is also likely that one of the two devices in question will have either a yellow, red, or blue box on the grid or a red triangle in the upper right corner of their box indicating a problem with that device. The additional screens are used in order to drill down deeper into the individual device and conversation statistics. An indication that this has occurred is readily available on the Active Devices Grid, by way of the blue triangle in the device ID box for device Select OK to accept the values and close the dialog or Cancel to disregard the settings and close the dialog.
This log stores the most recent events and can be easily overrun by devices being powered down if the logic is not 1784-k2dhp to 1784-uu2dhp this fact. The default setting is to capture all traffic.
Conversely, the bottom most table displays all of the communications statistics for traffic that has taken place with this device but 184-u2dhp originated by other devices. These can be used to determine worst case device performance. If more than one box is checked, then the selection is treated as a logical AND condition.
All of this information can also be exported to a “. Due to the timing of the capture being started and 1784-u2dph, single digit number differences may 1784-u2djp but any differences of 10 or more indicate a loss of communications between the devices in question.
Large percentages of network 1748-u2dhp can be absorbed by messages and retries directed at devices that are no longer on the network. Keep in mind that if a capture file is set to wrap, the original statistics are calculated over the entire capture session as opposed to merely representing what has been captured to disk. Order Contact Us Reseller Portal. The information provided in the statistical analysis usv can be used to survey and benchmark existing networks, assist in the commissioning of new networks or network expansions, and diagnose intermittent device communications.
If you recreate the statistics from the File Menu, your original session statistics will be overwritten to reflect only the data captured to the disk file.

Early detecting and intervention will prevent small problems from escalating into huge network downtimes. The Network Event Log provides supplemental 1784-2dhp regarding how often a particular device is not responding or is a long responder.
This information provides additional details about the health of your network. You can also order NetDecoder online. This type of filtering eliminates capturing unnecessary frames and allows the user to quickly pin-point the source of the network problem. You must have firmware version 1. Notice that the display breaks the various conversations down into their individual components; Commands, Replies, Acknowledgements, and Negative Acknowledgements.
The device IDs are usbb numbers running from a value of to octal. However, Frontline no longer sells the DL Once a token is received, the receiving device can place Data Messages on the network usually up to 4 at a timewait for Acknowledgements or Timeouts, send a Solicit to the next device on the solicit list or pass the Token to the next Token Successor. Statistics files are named using the same name as your capture file and a file extension of “. You will notice that in the example below, Device appeared on the network and then took more than 5 seconds, but less than 60 to respond to commands sent to it.
The supported frame types include:. Note that in general, the number of Commands, ACKs and Replies should be equal on a well-behaved network.

This display will detail all traffic to or from the device in question. It is possible to save both session and capture file statistics by saving the capture file to another name and then recreating the statistics from the File Menu.
