Error Processing

4-9-2 Errors Detected by Analog I/O Unit
Bit
Word n+9
When an error occurs at the Analog I/O Unit, the ERROR indicator on the front
panel of the Unit lights and the error code is stored in bits 08 to 15 of IR word n+9.

Error code
For the IR word addresses, n = 100 + 10 x unit number.
For Units #A to #F (10 to 15), n = 400 + 10 x (unit number – 10).
Error
code
8 0 In adjustment mode, offset or gain
cannot be adjusted because input
value is out of the permissible
range for adjustment.
8 1 In adjustment mode, adjustment
cannot be performed because the
specified I/O number is not set for
use or because the wrong input or
output number is specified.
8 2 A disconnection was detected.
(See note.)
8 3 The output setting range has been
exceeded.
8 8 An EEPROM writing error has
occurred while in adjustment
mode.
F 0 The specified I/O number is not
set for use. (The loop-specified
number.)
F 1 A number outside of the 0 to 9999
BCD range has been specified for
the ratio set value.
F 2 The wrong output status for when
conversion is stopped has been
specified.
F 3 The wrong number of samplings
has been specified for mean
processing.
Note Disconnection detection (82) operates for input numbers used with a range of 1
V to 5 V (4 mA to 20 mA).
Errors indicated with 8j codes are automatically reset when proper counter-
measures are taken. The errors indicated with Fj codes are cleared when the
power is turned on after making the correct settings and when the Special I/O
Unit Restart Bit is turned OFF, ON, and OFF again.

Countermeasure
If making the adjustment by
means of a connected input
device, first adjust the input
device before adjusting the
Analog Input Unit.
Check whether the word n I/O
number to be adjusted is set to
21, 22, 11, or 12.
Check whether the input or output
number to be adjusted is set for
use by means of the DM setting.
Check the rightmost byte of IR
word n+9. The inputs for bits that
are ON may be disconnected.
Restore any disconnected inputs.
Correct the set value.
Turn the Set Bit OFF, ON, and
OFF again.
If the error persists even after the
reset, replace the Analog I/O Unit.
Set the I/O number for use.
Specify a number from 0 to 9999
BCD.
Specify a number from 0000 to
0002.
Specify a number from 0000 to
0004.
