Image file name

Appends the saved image file name linked to the read data (including an
extension).
When no image is saved, "(no file)" is appended.
When there is an image to save, the saved file name is appended.

(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
FTP

: bmp or jpg

*1 (no file) occupies 9 bytes.
*2 When a reading error occurs, the data for the number of parameter banks

registered are appended.

„

Group name (When the Master/Slave function is used)

Appends the group name to be set when using the Master/Slave function.
• Data format

Group name: Up to 16 characters

„

Master/Slave ID

Appends the unit ID to be set when using the Master/Slave function.
• Data format

nn: Unit ID (0 to 31)

„

Read time

Appends the time required for the reading.
• Data format

nnnnn = reading time (1 - 65535)

„

Checksum

The checksum is calculated using all characters that are not part of the header or
the delimiter and is then appended immediately before the terminator with 2
characters.
