Yokogawa Technical Report
Overview:

YOKOGAWA has successively released the DARWIN series (DA100/DC100/DR130, 230, and 240) as network- connectable data acquisition instruments, the DAQSTATION DX series as key industrial recorders, the MobileCorder MV series as measurement recorders, and the DAQSTATION CX series, a new product that comes with a PIC control function in addition to having the functionality of the industrial recorders.

Yokogawa Technical Report
Overview:

Yokogawa has set a new standard in data acquisition by rolling out the DARWIN series in 1995. The concept behind DARWIN is to offer features that are normally conflicting such as data acquisition that is easy-to-use yet highly expandable, by combining a data acquisition engine, a measuring unit with display and output mechanisms.

There is no strict specification for the input current value of DCV/TC INPUT, but the current value can be determined from the following specification. DCV/TC INPUT specification Max input voltage: V 2 VDC range, thermocouple, RTD: ±10...
You can, starting with style 8 of the DA. Setting command: VS. Control execute command: VD. The DR and DC do not support this. With DAQ32 and DAQ32Plus you can set up output relays, but you can't actually operate them with commands. You can also ...
Is there a limit on the extender modules?
(ns-faq-darwin-8052-select)
Extender modules can be connected to the main unit (DA100-1) and subunit (DS400, DS600). However, only 1 extender module can be connected to each. Total cable length: expansion cable (max. 500 m) + extender cable (max. 30 m). Even if using an extende...
For 0.5 second models, temperature is measured for RJC every 2.5 seconds (with a 0.5 second scan, since the time for processing temperature measurement, burnout, and other factors is too short, measurement occurs every 5 cycles). For 2.0 second mode...
No, on DARWIN, only a vertical parity check is performed.
The voltage generated when a burnout current of 4.2 mA flows to the measuring terminal circuit is measured in the 60 mV range, and a determination is made. If 42 mV (10 kΩ) or more, the result is 0 (open). If less than that, 1 (closed).
Generally they are not initialized if the modules are not different from the previous system. However, initialization happens if slots are in the following conditions. Slot replaced with a module of a different model name or style number Slot who...
This requires upgrading the DARWIN hardware style. Please submit for factory rework.
On the RS232C communication module, set communication parameters by using the dip switches on the front of the module. Make sure the communication module’s dip switches match what is displayed on the DAQ32's “Environment, diagnosis, a...
Check whether "Alarm data" is checked in the DAQ32Plus Logger acquisition conditions. If not, the alarm on the DAQ32Plus screen remains green and doesn't turn red even if an alarm is reported on the DARWIN hardware.
The range of the strain input module depends on the measurement mode and gauge method. (see the table below) Meausrement mode 2K 20K 200K 1 gauge method -2000 to +2000µε -20000 to +20000µε...
Unless you set the counter to go back to zero with the SETUP function, an overflow results.
Overview:

Unless you set the counter to go back to zero with the SETUP function, an overflow results.

Yes. The integral value is the scale calculation.
Yes. However, please note the following settings. Make multiple memory partitions. On the SET UP menu under MEM SET, set FILE COPY & DELETE=OFF, and FILE ROTATE=ON (WRITE MODE=REPEAT). Event actions must be set, for example: LOGIC BOX NO=1 ...
For voltage measurement, if 5% of range + range span is exceeded, an overrange occurs (±32767 is output). For temperature range, the +10°C measuring range is the upper limit. Ex) For the ±50 V range (span of -50 to +50), the upper l...
4.2 µA flows from a burnout power supply, resistance is measured, and the determination is made. : Thermocouple is normal: Less than 10 KΩ Thermocouple breaks, and while it is breaking: 10 KΩ or more
The input types are non-voltage contact and open collector. Hence, it is not necessary to input a voltage to pulse input. This specification shows the withstand voltage and current capacity determined for contacts or transducers. In other words, a co...
  RELATIVE: Count begins from the moment the timer time is set, and timeup occurs when a set time is reached. For example, if timer 1 is currently at 7 days/10 hours/00 minutes, and you set 01 days/10 hours/00 minutes, the timeup occurs every...
After entering Setup mode settings (including burnout), you have to store the settings using the XE command. If you don't send the XE command, the settings are ignored.
If you specify unidentified channels, no errors occur but the channels are ignored.
The Viewer cannot determine the numbers after the decimal with statistical computation on DI input. Data acquired and results computed by the BFD32 are affected by the decimal of the specified measurement range. For DI (contact input), a 4.2 µA...
  When measuring strain with initial balancing (EXEC), measurement is performed using the state with the gauge connected as a reference criterion. Therefore, you must balance the bridge with the gauge connected. This balancing is called initi...
In principle, they should continue to run even if their upstream subunit has a power failure. However, temporal effects will be experienced (data acquisition will be temporarily lost, or certain data might become damaged).
DAQ32 (DP120) or DAQWORX DAQ32 Plus (WX102) installed on Windows 7 or Windows Vista cannot change the IP address of DARWIN series Ethernet modules (suffix code /C7) or DARWIN series standalone models with the Ethernet communications option (model cod...
Yes. Set the IP address, subnet mask, and default gateway on the main unit.
Does DARWIN support Windows XP?
(ns-faq-darwin-8017-spec)
R10.03 and later support Windows XP.
The set of communication commands TS.GET.FM outputs data on the necessary number of channels (1 scan interval's worth). Accordingly, data cannot be output continuously. Also, the data acquisition on the software has nothing to do with the scan in...
Thermocouple data is generally not included with our digital devices. The accuracy of data measured with thermocouples is the combined accuracies of: the thermocouple itself; the temperature compensator; the linearization that approximates the thermo...
When applying a moving average, the decimal places matches the number of digits in the range.
