9.2.2 iVu Output Values
Using output values, the following information can be obtained:
•
ACK bits (acknowledgement bits) for input commands, including error codes
•
System indicators (Ready, Pass/Fail, Read/No Read, Output signals, Command Error, etc.)
•
Inspection History (Iteration Count, Pass Count, Fail Count, etc.)
•
Current Inspection Results (data of the sensor type contained in the inspection)
•
Command Responses
Refer to the sections on protocols for more information.
ACK Flags
For each of the Command Flags there is a corresponding ACK flag. The Vision Sensor sets the ACK flag when the
corresponding action is complete. Command flags cause actions to occur on the low-to-high transition of that flag. You
must clear the command flag after the corresponding ACK flag has been observed to be high.
As an example, to use the Trigger ACK flag, the programming steps for triggering an inspection would be:
1. Wait for ready.
2. Set Trigger command flag to 1.
3. Wait for Trigger ACK to go to 1.
4. Set Trigger command flag to 0.
Command Responses
iVu Plus Series Command Channel commands executed using command IDs may have a response value. Depending on the
Data Type, the response value will be contained in one or multiple registers. Refer to iVu Command Channel Commands
section of this document and the iVu Plus Communication's Users Guide for more information about the iVu Command
Channel.
9.3 Sensor Operation
Any Industrial Ethernet protocol can be used to trigger inspections, remote teach and perform command functions. On
iVuPlus BCR models, compare strings can also be set.
