Retry Function

At one inspection trigger, this function repeats scanning until the entire code is successfully scanned. The retry
function has four modes: normal retry, exposure retry (*1), scene retry, and trigger retry.
*1: The brightness (exposure) depends on the shutter speed and gain. When HDR is ON, the shutter speed and gain are automatically
adjusted for the optimum exposure. When HDR is OFF, the gain is fixed.

Retry mode
Normal retry Scanning is repeated the specified number of times at the specified interval until the entire code is successfully
scanned. The maximum count and interval are set.
The settings are configured in the retry settings of each scene.
Exposure retry Scanning is repeated the specified number of times while varying the exposure (when HDR is OFF, the shutter
speed is varied) until the entire code is successfully scanned. The brightness step (shutter speed step when HDR is
OFF), increment count, and decrement count are specified. The settings are configured in the retry settings of each
scene.
Scene retry Scanning is repeated the specified number of times while switching the scene until the entire code is successfully
scanned. [Auto] or [Fixed] is selected for the switch order.
[Auto]: Switches through the scenes in the order of highest frequency of use.
[Fixed]: Switches scenes in the set order.
Trigger retry When the parallel IN5 signal is ON, scanning is repeated until the entire code is successfully scanned.
To use trigger retry, the I/O input mode must be set to expanded mode.
None (default) Retry is not performed.
Combining retry modes
Normal retry, exposure (shutter speed) retry, scene retry, and trigger retry cannot be used at the same time.
When scene retry is ON, the normal retry and exposure retry modes in the same scene are OFF.
When normal retry, exposure retry, or scene retry is ON, trigger retry is OFF.
