DumpAsCSV
If this option is set to true, then the buffer will be directly dumped to the specified location as a *.CSV file in
the format specified below. If it is set as False, then the dump of the trend file will be in binary format; the
result of the dump operation is actually a couple of files, one with extension .dat and one with extension .inf.
An external utility is then required to convert it to a CSV format. These two files are both required by the
utility to operate the conversion.
DateTimePrefixFileName
When this Option is enabled the dumped File will have the Date and Time as Prefix to the name of the File.
For example if we are making a Dump at 10.10AM on 1-1-2012, then the file name will look like
D2012_01_01_T10_10_Trend1.csv. [DYear_Month_day_THour_Minute_Filename]
This helps to know the Time at which the Dump was executed and also to identify which one is the latest.
timeSpec
This option defines the time format used when dumping the trend to file.

Local: the time values exported are the time of the HMI device.

Global: the time values exported are in the Coordinated Universal Time (UTC) format.
Example:

Global
The software tool required to convert the dump files to CSV are available in the HMWIN Studio
NOTE
folder called "Utils" under the directory where the software is installed.
The tool needed to convert trend buffers is called "TrendBufferReader.exe".
The TrendBufferReader.exe tool can be invoked using a batch file with the following syntax:
TrendBufferReader -r Trend1 Trend1.csv 1
