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 Bits
For each of the Command bits there is a corresponding ACK bit. The iVu sets the ACK bit when the corresponding action is
complete. Command bits cause actions to occur on the low-to-high transition of that bit. You must clear the command bit
after the corresponding ACK bit has been observed to be high.
As an example, to use the Trigger ACK bit, the programming steps for triggering an inspection are:
1. Wait for ready.
2. Set Trigger command bit to 1.
3. Wait for Trigger ACK to go to 1.
4. Set Trigger command bit to 0.
Command Responses
iVu Command Channel commands executed using command IDs may have a response value. Depending on the Data Type,
the response value is contained in one or multiple registers. Refer to
iVu Command Channel Commands (iVu Command
Channel over Industrial Ethernet)
(p. 98)for more information about the iVu Command
Channel.
