Image file name
An image file name is set in the following format.
(1) Image count value (3 bytes) IMG : When saved in ROM/RAM
000 to 999 : When sent via FTP
• The number is counted from 000
at startup.
• The counter value is
incremented each time one
image is sent.
• When the counter value of 999 is
incremented, the value returns to
000.
(2) Image type (1 byte) S : OK image
L : Latest
E : Error image
W : Unstable image
N : Comparison NG
C : Captured image
X : No decoding process
(3) Operation number (2 bytes) 00 : Latest
01 to 10 : From timing ON/OFF to specified
number
#1 to #8 : Burst number
(4) Bank number (2 bytes) 01 to 10
(5) Image file extension ROM/RAM : bmp

„ When the edit image file name function is enabled
When sending images via FTP transmission with [Edit image file name] – [Use
script] set to Enable, image file names can be freely changed.
For the edit image file name function, refer to
"3-13 Edit data function/Edit
image file name function (Page 24)".
Image save mode
The following 3 image save modes are available:
• Save final bank image
• Save images after timing input ON
• Save images of the specified number before trigger input OFF
This section describes each mode.
Save the latest bank image
In this mode, the SR-750 Series performs reading operation and saves the image
at the timing when the read result is judged.
Depending on the reading mode of the SR-750 Series, saved images and the
determination timing for images to be saved are as follows.
Refer to
"4-4 Read Mode (Page 28)"
(1) _ (2) _ (3) _ (4) . (5)
„ Read OK/Comparison NG (When the preset/comparison
function is used)/Unstable image
(1) When the reading mode is the single read mode or multi 1 read mode
Only successfully read images of both the latest images and judged images are
saved.
(This is the example of when the parameter banks 1 to 3 are used.)
(2) When the reading mode is the multi 2 read mode
Judged images and parameter bank images successfully read are all saved.
For the latest images, only the image obtained last is saved.
(This is the example of when the parameter banks 1 to 3 are used.)
(3) When the reading mode is the burst read mode
For the latest images, all burst scanned images are saved.
For the judged images, only the images that can be decoded are saved.
(This is the example of when the burst execution bank is 1 and the number of
burst scans is 5.)
„ Read error
(1) When the reading mode is the single read mode or multi 1 read mode
When a reading error occurs, all parameter bank images used for reading
operation are saved one by one as judged images.
For the latest images, only the image obtained last is saved.
