UM-0085-B09 DT80 Range User Manual Page 148

The Diagnostics screen provides functions which may be helpful when diagnosing a problem with the DT80. You can:

• display the event log, which records events such as resets and power failures (Event Logs (P276))

• execute a self test, which verifies correct hardware operation (TEST Command (P275))

• generate a full service report. This includes the above items, plus several other details regarding the state of the

logger (SERVICEDATA Command (P277)). The report also contains details relating to the web client (i.e. your

PC and browser).

To perform the desired function, press the appropriate button. If this is the first time you have selected the function then it

will be performed immediately and after a short pause the data will appear. If you have previously selected the function

then the previously collected data will be displayed; press Update if desired to repeat the operation.

Program Screen

The Program screen simply displays a listing of the program text for the current job, similar to the SHOWPROG

command.

Data Retrieval

Unloading Data Using the Web Interface

The Retrieve Data screen allows you to transfer logged data and alarms from the DT80 to your computer. There are two

variants of this screen:

The Basic screen will be shown by default. You can retrieve data and/or alarms for the current job: either all logged

data, or a specified time range, or just the new data (that is, data logged since you last retrieved data)

The Advanced screen (see Figure 41) is the same, except it also shows details relating to the number of logged

data/alarm records for each schedule (similar to the Schedules screen (P146)). You can also select the schedules for

which to retrieve data.

This process is essentially the same as unloading the data, using the

COPYD command (see Retrieving Logged Data

(P98)), in that the logged data is read out of the logger's store files and saved in CSV or DBD form.

CSV data is in form that can be loaded directly into a spreadsheet application such as Excel.

DBD format is the logger's native binary format, which is generally quicker to transfer. DBD files can be opened by the

dataTaker dump_dbd utility and certain data analysis packages.

The general procedure for retrieving data is:

1. Specify the data format and the extent of the data and/or alarms to be retrieved, using the various controls

(described further below).

2. Press Retrieve Now.

3. A "Save As" dialog will be displayed where you can enter a filename. The selected data will be saved to this file

in CSV or DBD format.

4. Locate the saved file and open it using a suitable application.
