During the Data and Image export operation the sensor's output channels might become full. This can
occur if the sensor is producing export data (frames) faster than the data can be exported from the device
(due to bandwidth limitations) or faster than the client is reading the channel export data.
This setting affects how the sensor will behave in this situation.
•
Select Hold READY to ensure that all frames are transmitted. In this case, the READY signal will
remain inactive (sensor is busy) until the new frame has been added to the channel for
transmission. Triggers might be missed during this time.
• Select Do not hold READY to cause the sensor to discard the new frame if the channel is full and
thus activate the READY signal immediately after the current inspection is complete. In this case,
the discarded frames will not be transmitted.
8.3 Testing and Troubleshooting iVu Plus Communications
8.3.1 Understanding the Communication Log
The iVu Plus sensor includes the following Communication Logs:
•
Command Channel Log that can be used to ensure that commands are properly formed (syntax is correct), and
provides a history of commands issued along with responses to these commands. To access the Command Channel
Log, go to Main Menu > Logs > Communication Logs > Command Channel
• Data Export and Image Output logs that are purely output logs (that is, there is no receive activity to log)
Some notes about the logs:
•
To see an expanded view of each entry, click on the small right-triangle control on each entry
• To save the log, click the save icon. The saved communication log can be loaded into the emulator for
troubleshooting offline
The table below describes the icons used in the Communication Log, the up-arrow indicates an incoming request to the iVu
from the control device; the down-arrow indicates an outgoing response from the iVu to the control device.
Icon Description
Port opened.
Port closed.
Indicates that the command has been processed without errors.
Indicates that the incoming entry is stalled (no new bytes), or end-of-frame delimiter was not received, or
client is not reading data on ethernet
.
If the response frame contains an error or is dropped, the log entry icons for the request and the
response frames will be colored red, and the displayed error count will increment by one.
If the command takes a long time to process, the last long entry will change to an hourglass (for
example, during trigger of long inspections).
For Ethernet channels:
•
The channel's log will show an Enabled entry that indicates which port is being listened to
• When a client connects, a log entry is added that indicates which IP address connected
