1.1 About DARWIN

What is DARWIN?

Created from a completely new concept that is based on modular architecture, this group of next generation data acquisition systems is called DARWIN (Data Acquistion and Recording Windows).

Today many data acquisition networks are increasingly being linked together. More than ever before, large volume, high speed, accurate, easy-to-use communication functions are essential in many disciplines.

In the world of measurement and control where the number of measurement points has increased sharply, the ability to acquire information from a large number of points easily and economically is crucial. Interfacing to a personal computer allows simplified utilization of the information while improving quality and efficiency.

DARWIN is based on a unique, new concept to meet these needs. The art of measurement is revolutionized by DARWIN which integrates functions of conventional recording and data logging.

Most existing data acquisition equipment has been the all-in-one type in which the measurement section and display/recording section are contained in one box. While this simplifies operation on the one hand, it is difficult to adapt to changes in the measurement environment and also makes expansion difficult.

DARWIN uses a data acquisition engine and remote I/O modules which are completely separate from each other. It is an entirely new product line which quickly and flexibly copes with various restrictive conditions and changes in specifications.

Supported by a personal computer, a whole line-up can be created starting with the data acquisition systems DA series which performs data logging. For example, using a printer as the output device, the equipment becomes a hybrid recorder (DR series).

Three models are available in the DR series: the DR130, DR230 and DR240. The DR130 is a portable hybrid recorder, the DR230 is a desk-top hybrid recorder, and the DR240 is a panelmount hybrid recorder (component type).

2.2 Measurement Input Functions

Input Type

DC Voltage

Measurements can be done after selecting the measurement range per channel. The minimum range is 20mV, the maximum range is 50V.

Thermocouple

Measurements can be done after selecting the type of thermocouple per channel. The available types are R, S, B, K, E, J, T, L, U, N, W and KPvsAU7FE.

Reference Junction Compensation (RJC) can be set to either use Internal RJC (INT) or External RJC (EXT) per channel.

Burnout function can be set OFF per channel or it can be selected in which direction the trend line will move if burnout occurs (right or left)

Resistance Temperature Detector

Measurements can be done after selecting the type of resistance temperature detector (RTD) per channel. The available 17 types are Pt100(1mA), Pt100(2mA), JPt100(1mA), JPt100(2mA), Pt50(2mA), Ni100(1mA)SAMA, Ni100(1mA)DIN, Ni120(1mA), J263*B, Cu10GE, Cu10L&N, Cu10WEED, Cu10BAILEY, Pt100 (1mA) high resolution, Pt100 (2mA) high resolution, JPt100 (1mA) high resolution and JPt100 (2mA) high resolution.

Contact Input

The type of contact input can be selected from voltage level input or contact input, and recording can be set ON or OFF per channel. In case of the voltage level input a voltage level up to 2.4V results in recording OFF, whereas a voltage level of 2.4V or more results in recording ON.

AC Voltage/Current

The effective voltage, effective current, active power, reactive power, apparent power, frequency, power factor and phase angle can be measured. The measuring range is common to all terminals. The input terminals of the module with this input mode are not consistent with a setup screen in terms of the channel number.

Skipping Input Channels

This function allows skipping measurement, recording and display of channels you are not using. Measurement, recording and display will not be done for the skipped channels.

Reference Junction Compensation (RJC)

This function is to be used when measuring temperatures using thermocouples. The voltage generated by a thermocouple depends on the temperature of the spot of measurement and the reference junction temprature. Reference junction compensation is a function which compensates the temperature at the side of the measurement instrument to 0 degrees C.

To compensate for the environmental temperature an internal circuit can be selected, or compensation by a fixed compensation voltage value (external) can be set.

2.2 Measurement Input Functions

Scan Interval

•The duration of time (one scan) in which the measurement of all channels is carried out, is called the scan interval.

•This interval can be set to any value from 2 to 60s, and this range is the same for the 10ch, 20ch and 30ch model.

A/D Integration Time

This instrument measures the input signal after putting it through an A/D converter. In order to minimize the noise imposed on the input signal, specific integration times exist.

The integration time can be selected from 20ms (50Hz), 16.7ms (60Hz) and 100ms (10Hz). When “AUTO” is selected, the integration time will be automatically decided according to the 50/ 60Hz frequency of the power supply.

AUTO does not function if the instrument is a DC power supply model (Selecting “AUTO” will set the A/D integration time to 20 ms (50 Hz)). If you are using the instrument on a 60-Hz power supply, set the A/D integration time to 16.7 ms (60Hz).

Input Filter

A filter can be set ON/OFF to reduce normal mode noise. Effects on normal mode noise are as follows depending on the filter being ON/OFF (theoretical values).

2.3 Recording Functions

Chart Speed

The speed at which the chart moves when performing trend recording can be selected from any value between 1 to 1500mm/h.

Two types of chart speeds can be set. When you are not using the Event/Action function, which will be described later on in this manual, chart speed 1 will be valid. When the Event/Action function is being used, you can select whether chart speed 1 will change to speed 2 according to the event status.

Recording Mode

Two types of recording modes are available; analog trend and logging mode. The default setting is analog trend mode.

Analog Trend Mode (refer to the next page for a recording example) Trend Recording (Dot recording)

The recording principle is that, according to measurement data and recording conditions, the correct position on the chart will be decided and on that position the dot will be printed. Trend recording conditions consist of the following.

•chart speed

•channels to be recorded

•recording color (refer to page 2-9)

•recording interval (refer to page 2-9)

•recording span (refer to page 2-10)

•recording zone (refer to page 2-10)

2.3 Recording Functions

Recording Format

You can modify the recording format of measurement values according to your own preferences. The following selections are available.

Items common for Analog Trend and Logging mode Printing Channel No. or Tag

When printing measurement values, the corresponding channel number or a preset tag can be recorded with it. This selection will also affect the display the same way. The number of characters of a tag which will be printed out, can be selected too.

Items for Analog Trend Mode

• Printing Starting/Stopping Time of Recording

You can select whether to print the time of starting/stopping the recording (refer to page 2-10) on the right side of the chart. The first time recording starts after the power has been turned ON, only the starting time will be printed. After that, the current starting time will be printed together with the stopping time of the previous recording. To the right of the starting time a bar will be printed as a reference point to the time of starting.

•Selecting the Number of Columns for Digital Printouts

You can select how many columns (where one column equals data of one channel) will be used in one line for printing out measurement data.

•Selection of the Pitch of Channel Printouts

You can select at which distance the channel numbers (or tags) will be printed. You can also select this printout OFF. When tags have been selected, this distance applies to the tag printout.

•Selection of the Pitch of Title Printouts

You can select at which distances the title will be repeatedly printed. You can also select this printout OFF.

•Selection of the Scaled Values Printout

You can select the printing pattern for scaled values (refer to page 2-10). You can also select this printout OFF.

•Selection of the Reference Point of Scaled Values

You can select whether or not to print a reference point for the positions of the scaled values.

Items for Logging Mode

•Selection of the Recording Direction (Horizontal/Vertical)

You can select whether printouts will occur in horizontal or vertical direction,

Example of a printout in horizontal direction

2.3 Recording Functions

Recording Colors

The color of trend recordings can be selected per channel. The colors which can be selected are black, purple, red-purple, navy blue, red, blue, brown, green, orange and yellowish green.

The recording color of the numerical values in the logging mode is purple only.

Recording Interval

The time during which one scan of trend recording or numerical printout is carried out is called the recording interval.

Recording interval for trend recording

This recording interval can be selected from AUTO or FIX.

•AUTO

The recording interval is decided automatically depending on the measurement (scan) interval and chart speed in order prevent the dots from overlapping. However, in cases where this calculation would render the recording interval smaller than the scan interval, the recording interval will equal the scan interval.

Recording interval = Scan interval × N

where N is an integer satisfying N ≤ 720 / (scan interval × chart speed). 720 is fixed.

Example: when scan interval is 2s; chart speed is 100mm/h then N ≤ 720 / (2 × 100) = 3.6

The closest matching integer is 3.

Accordingly, the recording interval becomes 2 × 3 = 6s.

•FIX

Recording is carried out at an interval which is the same as the scan interval (2 to 60s) regardless of the chart speed.

Recording interval for digital printouts

This recording interval can be selected from MULTIPLE or SINGLE

•MULTIPLE

Six preset recording intervals (Timer 1 to 6) can be set and a recording interval can be selected per channel. The timer setting can be selected from relative and absolute.

•Relative time: Time will be counted from the point of turning the power switch ON or of resetting the timer. Each time the preset length of time is reached (and thus when time is up), recording will start.

•Absolute time: A reference time is set, and from that time recording will start at preset time intervals (each time when time is up).

•SINGLE

The logging interval is decided automatically depending on the chart speed and the number of columns for digital printouts.

Recording interval in logging mode

This recording interval can be selected from MULTIPLE or SINGLE

•MULTIPLE

Same as for the analog trend mode

•SINGLE

From the above mentioned six preset recording intervals, the interval set as Timer 1 will become the recording interval.

Resetting the Recording Interval (Timer Reset)

This function will reset the elapsed time of the above mentioned MULTIPLE recording interval to zero. Usually recording will start according to the recording intervals, but when you reset the elapsed time using this function, the results are the same as for time-up.
