DeviceNet Analog Remote I/O
● It adjusts the gradient of input/output value or scale
value. It is able to read/write by Configurator or Explicit
message.
● It is applied when Adjust Gradient Flag bit is set as ON
at Function Choice of Analog Input Point Object. Set
the range at Adjustment Gradient value.
● Adjustment range: -5 to 5%,
Setting range: -500 to 500 (factory default: 0)
E.g.) When input value is 1000, Adjustment Gradient is
500 (+5%) X’=aX, a=1+Adjustment Gradient (0.05),
X=1000, X’=1.05×1000=1050
I/O comment
● You can set the comment for I/O. It is able to read/
write by Configurator or Explicit message.
● Set I/O comment by Explicit message at I/O Comment
of Analog Input Point Object, Analog Output Point
Object.
● Setting range: max. 32 characters
Gradient adjustment
Offset adjustment
●
This function is to adjust the error occurring from
external analog sensor, etc, not from the unit itself. It is
also applied to analog output. It is able to read/write by
Configurator or Explicit message.
●
It is applied when Adjustment Offset Flag bit is set as
ON at Function Choice of Analog Input Point Object.
Set the value at Adjustment Offset Value.
●
Adjustment range: -5 to 5%,
Setting range: -500 to 500 (factory default: 0)
E.g.) When input range is 0 to 10V, Full Scale 0 to 16000,
input value is 1600 (1V) and Adjustment Gradient
500 (+5%), X’=X+b, X=1600, b=16000×0.05
(added input value and percentage of Full Scale)
X’=1600+800=2400 (1.5V)
Input digital filter
●
This function is used when input value vibrates or
repeatedly shake by included noise at input signal.
Accurate control is available by stable input with this
function. It adopts moving average filter method not
to affect sampling cycle. It is able to read/write by
Configurator or Explicit message.
●
It is applied when Moving Average is set as ON at
Function Choice of Analog Input Point. Set the number
of digital filters at Moving Average Filter of Number.
●
Setting range: 0 to 8
(factory default: 3[Moving Average No_8])
●
When operating analog input cable (voltage/current
input) is disconnected, Broken Wire Flag Bit turns
ON at Analog Status Flag Read of Analog Input Point
Object. (It operates only for 1-5V, 4-20mA input range.)
It is able to read by Configurator or Explicit message.
●
If this value is below -5%, it recognizes disconnection
and displays ‘32767’ as data value.
Disconnection detection
Input min./max. value save
●
Min./Max. save when power is ON
It saves min./max. input value from power ON the network.
(When network power is OFF, the saved min./max. input
value are cleared.)
It is able to read by Configurator or Explicit message.
When Clear Max, Clear Min Flag bit of is ON at Function
Choice of Analog Output Point Object, the saved values
are cleared and it saves current min./max. value of
current input.
●
Min./Max. save when Peak/Bottom Hold signal
is ON
It memorizes the max./min. value while Peak/Bottom
signal is ON. When Peak/Bottom signal is OFF, they are
saved.
It is able to read by Configurator or Explicit message.
It is applied when Peak/Bottom is set as ON at Function
Choice of Analog Input Point Object. You can check the
value of Peak/Bottom at Peak Value and Bottom Value.

It compares analog input value or the operation value
and alarm set value (HH, H, L, LL) and Analog Status
Bit flag turns ON at Function Choice of Analog Input
Point Object. It is able to read by Configurator or
Explicit message.
●
If the value is within the setting range between ‘H’ and
‘L’, it is available to apply by turning ON Pass Signal
Flag bit at Analog Status Flag Read of Analog Input
Point Object and turning ON/OFF Comparator Flag bit
at Function Choice.
