These data show the AD268’s operation status.

Bit position →FEDCBA9876543210

0000

Bit Name Description

0 to 2 Input t ype Shows the input type.

000 (0) = 0 to 5V/0 to 20mA

001 (1) = 0 to 10V

010 (2) = 1 to 5V/4 to 20mA

100 (4) = ±5V

101 (5) = ±10V

3 to 5 - Reserved

6 Channel skip 1 when the channel skip is designated.

7 Input type setting

error 1 when the input type designation is invalid.

8 Wire break 1 when wire breakage is detected. (Effective only for 4 to 20mA

input)

9 Input limit 1 when the A/D conversion data i s limited because of the range

over.

A MPU er ror 1 when the AD268’s processor is not normal.

B ROM status 1 when the AD268’s EEPROM is not normal.

C DP-RAM stat us 1 when the AD268’s DP-RAM (buffer memory) is not normal.

D- Reserved

E Ex ternal 24V error 1 when the external 24Vdc is not norma l.

F Initializing 1 during the AD268 is in initialization process.
