How to log the data of specified period of time
We sometimes receive the inquiry about "How to log the data in accordance with the period of time when the device is operating" or "How to log the communication data sent in specified period of time" from engineers working on the production lines.
This time by LINEEYE analyzers we introduce the way to execute measurement with time appointing or measurement coupled to power ON/OFF. As the function for this purpose differs depending on the model, please select the one which suits your intention. Also if you want to log the data for long time, the data should be saved on the external memories such as CF card or SD card. This article treats the case of the analyzers for serial communication such as RS-232C/RS-422/RS-485, other LINEEYE analyzers may have the same kind of function, If you want to know the detail please contact us.
In the case of LE-8200A / LE-8200
These are the standalone battery powered analyzer with large color display.
You can confirm the logged data without using PC on site.
| Time appointing measurement | Yes |
|---|---|
| Power OFF while waiting on schedule measurement | Yes |
| Start measurement with power ON | No (You can check existence or non-existence of external power when you start measurement.) |
| Battery run time | Max. 4 hours (depending on how it works and circumstances) |
| Supported external memory | Max. 64GB CF card (LE-8200A also supports USB flash) |
Appointing start/stop measurement time, Power OFF on waiting (P-OFF standby), and Power check of when it starts the measurement (Power check) offer the measurement in specified period off time like following example.
Example: Measurement on weekdays while power supply is ON. Saturday and Sunday the measurement is not needed and power supply is also OFF.
- The analyzer starts measurement from the run time and stops at the stop time on weekdays.
- The power of the analyzer turns OFF (standby) after stopping measurement and on the next day it automatically turns ON the power before start measurement and then restart the measurement.
- When the power is not supplied for holidays, power check function automatically works and does not execute the measurement.
By this function you can avoid the situation in which the measurement starts on holidays and runs out the battery and it cannot execute measurement.
In the case of LE-3500R / LE-2500R / LE-3500 / LE-2500 / LE-1500
These are the standalone battery powered analyzer with monochrome display.
You can confirm the logged data without using PC on site.
| Time appointing measurement | Yes |
|---|---|
| Power OFF while waiting on schedule measurement | No |
| Start measurement with power ON | Yes |
| Battery run time | Max. 8 hours (depending on how it works and circumstances) |
| Supported external memory | Max. 32GB CF card (LE-3500R) Max. 16GB CF card (LE-3500, LE-2500R) Max. 8GB CF card (LE-2500/LE-1500) |
Appointing start/stop measurement time and automatic initiation of measurement by power ON are available. By these functions, for example, you can execute a scheduled measurement on weekdays like following.
Example: Measurement on weekdays while power supply is ON. Saturday and Sunday the measurement is not needed and power supply is also OFF.
- The analyzer starts measurement from the run time and stops at the stop time on weekdays.
- On Saturday and Sunday, when power supply stops, the analyzer run out the battery and stops. Thus it does not execute measurement then.
- On Monday, when power supply restarts, gStart measurement with power ONh works and the analyzer starts the measurement.
In the case of LE-200PR / LE-200PS / LE-150PS
These are the models which serve as PC-connectable communication protocol analyzer or data logger.
The compact body is suitable for installment on the site for data logging and data check when any problem occurs. To monitor the logged data PC is needed, but you can see if the communication data runs or not by seeing the LED on the analyzer. The following table shows the function of the analyzer as data logger.
| Time appointing measurement | Yes |
|---|---|
| Power OFF while waiting on schedule measurement | Yes/No depending on the situation (It turns to be power saving mode while waitingj |
| Start measurement with power ON | Yes |
| Battery run time | No battery. Built-in capacitor for protecting data at power failure |
| Supported external memory | Max. 8Gb SD card |
Appointing start/stop measurement time and automatic initiation of measurement by power ON are available.
These models does not have internal battery and cannot work without external power supply. These models also have the function to stop the measurement after saving the log file safely when sudden power failure happens. Thus these models can restart the measurement by using the function "and automatic initiation of measurement by power ON" when power supply resumes.
Example: Measurement on weekdays while power supply is ON. Saturday and Sunday the measurement is not needed and power supply is also OFF.
- The analyzer starts measurement from the run time and stops at the stop time on weekdays.
- On Saturday and Sunday it does not execute measurement because the power supply is OFF and it does not work.
- On Monday, when power supply restarts or when the indicated time comes, gStart measurement with power ONh works and the analyzer starts the measurement.
Web pages of LE-200PR, LE-200PS, and LE-150PS also have detailed example.
