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.

What is the stipulated current value of the DCV/TC input module?
(ns-faq-darwin-8054-spec)
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...
Can I forcibly turn the alarm output modules ON/OFF from a PC regardless of any input data alarms?
(ns-faq-darwin-8055-spec)
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...
What is the temperature measurement interval of the universal module's RJC (INT)?
(ns-faq-darwin-8051-spec)
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...
When loading data on a PC via RS-232C communication, is a horizontal parity check performed?
(ns-faq-darwin-8047-spec)
No, on DARWIN, only a vertical parity check is performed.
What internal processing occurs of the DI input (non-voltage contact input) from the universal input module and DCV/TC/DI modules?
(ns-faq-darwin-8050-spec)
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).
When I add a module and configure the system, are the settings initialized?
(ns-faq-darwin-8058-spec)
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...
I'm using a previously delivered DARWIN, but can I use an Ethernet module that supports a new style?
(ns-faq-darwin-8059-spec)
This requires upgrading the DARWIN hardware style. Please submit for factory rework.
I’m trying communication from a RS232C communication module (DT300-31) to a recorder using DAQ32 software, but *E0401 Communication error* is displayed and communication fails.
(ns-faq-darwin-8068-connect)
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...
I'm using DAQ32Plus. I set an alarm on the DARWIN (DC100). When the measured value rises, an alarm appears in the DARWIN (DC100) screen, but in the DAQ32Plus screen the alarm stays green (doesn't turn red).
(ns-faq-daqworx-13067-soft)
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.
When the measurement mode is 20 k and the gauge method is 4 gauge, the range is －5000 µε to +5000 µε(microstrain), but I can measure up to ±20000 µε. What is the accuracy?
(ns-faq-darwin-8062-spec)
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...
When the counter is up, does it go back to zero?
(ns-faq-darwin-8061-spec)
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.
Is the integral value on the input pulse module the calculated scale value?
(ns-faq-darwin-8060-spec)
Yes. The integral value is the scale calculation.
On the DC100, can I automatically save data to both SCSI and floppy media at the same time?
(ns-faq-darwin-8033-spec)
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 ...
When measuring voltage with a universal input module or DCV/TC input module, what is the limit value where an overrange occurs?
(ns-faq-darwin-8029-spec)
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...
What are the burnout determination criteria (just for thermocouples)?
(ns-faq-darwin-8007-spec)
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
What does the specification, "Signal supply rating 15 VDC, 30 mA" mean?
(ns-faq-darwin-8008-spec)
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...
What is the difference between RELATIVE and ABSOLUTE in the timer settings?
(ns-faq-darwin-8006-spec)
  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...
I do a burnout with the burnout setting command (XB) and set +OVER, but even when one side of the thermocouple is open the burnout check doesn't work.
(ns-faq-darwin-8005-spec)
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.
When outputting measured data, what happens if I specify channels not identified by the FM command?
(ns-faq-darwin-8002-spec)
If you specify unidentified channels, no errors occur but the channels are ignored.
When I acquire DI input with the BFD32 and perform statistical computation (averaging) on the Viewer software, I get computation errors 0 and 1.
(ns-faq-darwin-8004-spec)
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...
What do "initial balancing" (EXEC) and "initialization" (INIT) of the strain input channels mean?
(ns-faq-darwin-8010-term)
  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...
When expandable model subunits are connected serially, if a middle subunit's power cuts out, what happens to the downstream subunits?
(ns-faq-darwin-8013-spec)
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).
When I changed to Windows 7, I couldn't change the IP address of the Darwin Ethernet module. What should I do?
(ns-faq-darwin-8018-setting)
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...
Can I connect the main unit to a company network?
(ns-faq-darwin-8019-connect)
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.
How can I connect the DA100 to a PC via RS-232C and acquire data continuously? Also, can I synchronize the data acquisition on the software with the scan interval on the hardware?
(ns-faq-darwin-8015-connect)
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...
Why aren't thermocouples included in certificates of results?
(ns-faq-darwin-8014-other)
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...
