Hi all, I have what I thought was an extraordinarily simple application. I am using a DT85 to record 32 thermocouple measurements at 5 minute intervals. It is so simple I chose to make the configuration file on dEX-2 on the desktop. My problem is, when I save the configuration to the logger it scans and saves just fine but the schedule appears corrupt on dEX-2 (After channel 19, every even-nu
Hello, i wish to count the Sunshine duration with the DT82I-3 over the digital input. The Senser does have a Digital Output. Sun =1 otherwise =0 Now i wish to Count the total Time of the sunshine duration each day and log to CSV. This means. The Counter Starts each Midnight with : 0h 0m 0s and count the Time the digital input does have the input status "1"(high).
I would like to log data with the faster schedule. I saw on the forum that the faster is 25ms with some special parameters
_"If you have series 3 logger, 100 ms rate is not possible for 3 channels because the fastest rate would be 40 ms per 1 channel. But if you have series 4 logger, you can set 100 ms rate (fastest speed 25 ms/ channel).
I am having issues configuring a DataTaker DT82E-4 data logger that connects to a Toshiba GF630 flow meter. The output signal of the flow meter is 4 mA - 20 mA (corresponding flow rate 0 - 650 GPM). The flow meter has three wires: red (positive), white (negative) and green (ground). For wiring configurations, I used C3 - Independent Current Input using Internal Shunt (Red positive
Hi all, I have a DT80 series 4 , I want to connect a Power analyzer with RS485, Protocol communication: Modbus RTU • Baud rate : 4.8, 9.6, 19.2 kbps • Parity number: Odd, Even, None • Stop bit: 1,3 • Address: 1-247 • Connectors : 4 pole terminal ( integrated 120 Ohm terminator on T terminal ), So, I need your help for the configura
Sleep mode and its handy exceptions of the DT8x series dataloggers works well when using an internal battery. This may not be the case when the hardware setup is more complex with external high capacity batteries, DC converters, additional logic, etc.
It would be useful to use WK input, not only for waking purposes but preventing the logger going to sleep by keeping the input in logical low b
Hi all, I am having an issue with the DT80 series (FW 9.22) in that I am using it as a host device for a number of remote DT80s and I am looking to add 5x more remote devices (2-300 new CVs to bring in) over the 2Modbus commands. The Release Notes (9.18) state that we now have access to 65535 channel variables now of which I now need ~1300 but am experiencing errors in applying this.
I have a DT80 datataker attached to several type T thermocouples. My issue is that at some points the thermocouple temperature "jumps". It jumps, then continues at the new temperature for a while, then there is another jump and so on. This occurs even when I am not interacting with my setup. I have attached a graph showing two jumps, one at around 61 s the other at around 68 s. For ref
Hi, i was using this schedule RA"US"(DATA:OV:1D)100T 1V(A) 1V(A) 2V(A) 2V(A) i read in the manual that this 100T means it will trigger every 100ms, so i was expecting that i will get around 10 readings in a second. When i extracted the csv file i did not see more than 3 readings in the same second, so i am not sure this is accurate. Also i was expecting the time stamp to be more exact in t
Hi, i wqnted to copy some files onto the usb from a DT82I but it reads the usb too long. It is an empty one, and i am not sure what is happening. I want to mention that i have a schedule running and i am not sure if that influences. I was doing the followong logon, then run the schedule, then logoff and then i was able tonread the usb faster, but when i copyed the job, there were no recordings
Hi, i need to use 4 analogs , and make a chart with data while these analogs are changing values. So, i learned how to read these analog values instantly, but when trying to record them and put them in a chart i have lots of issues. Can you please give me some hint on what i need to code for the thing to work? I have some errors i think of syntax but u tried different things and still not
We finally release the new version of dEX which is a PC based application and free from flash player.
dEX® 2.0 is a simplified yet powerful software that allows you to configure and program your DT80 series data loggers. This configuration-based software allows you to configure the hardware, visualisation data and also debug your application on all DT80 series of loggers (includi
I try to write a script that will read the sensors on my Datataker DT85G but I run in to problems. I try to use the command server and connect to the local ip and can see all the commands but when sending commands I get problem.
It works fine is I logg into the Datataker through the web interface. Then I can send commands and receive results. However, if I'm not logged in through the web
Hi, I am a newbie in using the data taker. I was trying to create a schedule to read a DI every second for 1 minute. Then i deleted this schedule and i wanted to create another one..but this time any typr of codefor schedule i try to run is giving me this errror Cannot log: job untitled has existing data/alarms I have used deld..to delete all the data but it says there is no job
I have to use modbus function 0x03 to read values from a probe. But ist seems that the DT80 only supports 0x04. I was able to send the command manually via serial but when I try to read the answer which I can log in a terminal all CV variables stay empty. I tried %1b[CVx] and %1c[CVx] as well but no success. The exact command I used to read the values from serial port is 1SERIAL("%*3b
dataTaker does not have automatic detection on daylight saving however it is possible to introduce time manipulation through the code.
This is the code Jairus Pascoe from Metro Train which address daylight saving in Melbourne. Daylight saving in Melbourne start on 2 am the first Sunday of October and end on 2 am the first Sunday of April.
Current measurement using internal shunt resistor may prove difficult to achieve because there is measurement relay which separate output circuit of the sensor with shunt resistor. Using a default measurement delay of 10 ms may not be enough for some sensor.
Thus the only solution is increasing measurement delay, however some sensor may need a couple second to establish stable current
We need a simple way to totalizer a slow pulse from water meters and the same time reset counter each datalogging. Reset is easy using dEX with “Reset Counter”, but ”doesn’t exist the “Totalizer Counter for ever”
Our distributor in Chile sent us a request to implement PenMan-Montieth formula for evapotranspiration measurement using dataTaker. This formula requires several parameters that need to be calculated first from 10 measurements:
temperature (average, maximum and minimum)
relative humidity (average, maximum and minimum)
wind speed average
altitude from sea level
We manage to
This time I will explain about some possible causes of error related modem messages:
SESSION: Failed [Network check] - will retry This error is related to connection testing by pinging to dataTaker website after the internal modem established a data connection. If the pinging is unsuccessful, data connection will be dropped. There are 2 possible issues:
