■ 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

• 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

■ 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 10 V, Full Scale 0 to 16000, input value is 1600 (1 V) 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 (1.5 V)

■ 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])

■ 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.

■ Disconnection detection

• 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 1-5

V, 4-20 mA 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.

It is set as 1,000 per 1 V (mA).

In case of 1-5 V, 4-20 mA, it is applied from over

min. allowable range 0.8 V (800), 3.2 (3,200).

The below input value is break detection.

It outputs as min. allowable range.

It is set as default value 0 to 16000 (-8000 to

8000). (0-5 V, 1-5 V, 0-10 V, 4-20 mA, 0-20 mA:

0 to 16000, -5-5 V, -10-10 V: -8,000 to 8,000 )

Set high/low-limit value to apply at 'Scaling

Point 0 %' and 'Scaling Point 100 %.'

Setting range: -28,000 to 28,000

■ Input comparison

• 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.

HH alarm

H alarm

Normal Flag

L alarm

LL alarm

■ Hysteresis

• In case of comparison output, this function is to increase stability of comparison output

against vibration of input signal or chattering. It is able to read by Configurator or Explicit

message.

• It is applied when Compare Bit flag turns ON at Function Choice of Analog Input Point Object.

Set the value at Hysteresis Value.

• Setting range: 0 to 16,383 (factory default: 0)

■ Output value setting for com. error

• When communication error occurs, this function is to set output value of output unit by each

channel. It is able to read by Configurator or Explicit message.

• Set Fault state at Fault Action of Analog Output Point.

• Setting range: 0 to 3 (factory default: 1)

0: Hold Last State-maintains the last status, 2: High Limit-outputs max. value,

1: Low Limit-outputs min. value, 3: Zero Count-outputs 0 %

■ Status flag monitoring

• When the network power voltage is lower than the set value or unit operation time is over

the set value, monitoring is available by Status Bit of Application Object. It is able to read by

Configurator or Explicit message.

• Flag Bit

Bit 0: Reserved, Bit 1: Network Power Voltage Drops (below the set level),

Bit 2: Life State (Unit), Bit 3: Reserved, Bit 4: Reserved, Bit 5: Reserved, Bit 6: Reserved,

Bit 7: Reserved

■ Analog data allotment

• This function is to allot analog data. Select the desired data to transmit it to the master unit.

It is able to read by Configurator or Explicit message.

• Set the allotment at Analog Data 1/2 Allocation selection of Analog Output Point.

• Setting range: 0 to 2 (factory default: 0)

0: Analog Input Value, 1: Peak Value, 2: Bottom Value
