Scale L, Scale U, and Decimal Point
Enter the upper and lower limit values to which you wish to convert the input values. Set
the decimal position by the number of digits to the right of the decimal point.
When the scale L and scale U values are set to the same value or when a value outside
the range is entered, they are corrected when the data are checked.
Unit
Clicking the unit display area enables entering a new unit.
Enter the unit using up to six characters.
Alarm
Four alarms (Alarm 1 to 4) can be specified on each channel.
Type
Select from [H], [L], [h], [l], [R], [r], [T] or [t]. [h] and [l] can be specified on difference
computation channels only. Select [OFF] to disable alarm.
Alarm Value
Alarm is generated using the specified value as the boundary. The selectable range of
alarm values vary depending on the input mode and range.
Alarm Delay
This applies to delay upper (T) and lower (t) limit alarms.
Alarm is generated when the measured value stays above or below the specified alarm
value for the specified time (delay period).
Relay
To output relays, select the output relay number. Otherwise, select [NONE].
Input Filter and Moving Average
Moving average can be specified on models DX106P, DX112P, DX210P, DX220P, and
DX230P.
Input filter can be specified on models DX102P, DX104P, DX204P, and DX208P.
Input Filter
To use the input filter, select the time constant (2 s, 5 s, or 10 s).
Moving Average
To use the moving average, select the sampling count (2 to 16).
Tag
Up to 16 characters can be entered for the tag.
You can use the tag name instead of the channel number to be displayed on the screen.
The [System Mode] screen is used to select whether to display the channel number or
the tag name on the screen.
Display Zone
You can select the range of the screen in which the waveform of each channel is to be
displayed.
Specify positions (%) on the display scale for the upper and lower limits.
The conditions for setting the zones are as follows:
• Range: 0% to 100%
The lower limit must be less than the upper limit
• The difference between the lower and upper limits is at least 5%.
