User Manual
27. POS Data Logging
POS collects data from many different sources. One type of data log file contains all the
operating data for each individual Voltage Control. There is a separate file created for each
control on each day. The filenames begin with the control name and a dash (-) character,
followed by the year, a two-digit month code and then a two-digit day code. For example, the
data in the file
A5-20020417.DAT would be for voltage control A5 on April 17,2002. Another important data log
contains all the precipitator data including the analog load and opacity signals along with
optimization parameters and average electrical readings from the precipitator. There is a
separate file created each day for each precipitator on the system. The filenames begin with the
precipitator name and a dash (-) character, followed by the year, a two-digit month code and then
a two-digit day code. For example, the data in the file PRECIPB1-20020417.DAT would be for
precipitator B on April 17, 2002.
Data is also logged for each SmartSense, MicroRap Rapper Controller, soot blower, and flue gas
conditioning unit connected to the POS system. Like the voltage controls and precipitator log
files, a file is created every for each module attached to POS beginning with the unit name and a
dash (-) character, followed by the year, a two digit month and then a two digit day code.
All of the data logs also has a matching “*.LOG” file. This file contains the time and date
information the POS uses internally to get historical data.
Data File Locations and Maintenance
Since there is one file generated each day for each voltage control, precipitator, and any other
module on the system, regular maintenance is required to prevent the possibility of filling up the
computers hard disk drive. There will be a different directory for each month of data that stores
the *.DAT files. The files are stored in the C:\VTS\POS\LOG\year-month# directory. If you
require extended historical data, we recommend you back these files up using the POS Back-Up
Utility. The files can then be transferred to a removable media such as a tape drive or CD
Burner.
Viewing Data
Data that has been logged by POS can be displayed in two different ways.
1) Live and historical data for precipitators (and voltage controls in the current precipitator)
can be viewed using the Precipitator Log.
2) Data can be used to generate custom reports that can be saved, printed, displayed onscreen
or even emailed using the Report Generator.
