Virtual Instrumentation Logging System - VILS

VILS turns any PC into a versatile logging system data logger screen

An extension of the VIPS software, VILS allows a PC to be configured into a versatile and comprehensive Data Logger or Data Acquisition system.
Logging runs can be started and stopped in numerous different ways
Uses low cost VIPodS or VInterface hardware connected via the parallel port.
Stores data to disk in four different formats
All other VIPS functions still available, eg Oscilloscope, Bar Graph and Panel Meter displays.
Output pods can still be used to control the experiments
The VInstrumentation Products page should be consulted to obtain the full capabilities of the VIPodS interface hardware and software.
A demonstration version can be downloaded.

Logger Configuration
VIPodS
	Up to 4 VIPod input pods (VIPod10 or 10/20 analogue Input, VIPod30 or 50 logic input and VIPod101 voltage or temperature input) can be logged at the same time. 32 voltage channels, 32 logic channels or 24 temperature channels can be logged at speeds in excess of 10K samples per second. Input and output pods can be mixed on the same system but output pods are not logged.
VInterface
	The analog inputs and logic inputs can be logged.
All hardware
	Positions can be linked in a master/slave configuration or can act independently. The master/slave relationships, the logging file names and the logging format are set up from the position drop down menu. The operational conditions are set on-screen when logging of a position is selected.
Logging Modes
A comprehensive range of logging modes are provided that allow you to set up logging at time intervals or on alarms. In alarm logging mode, the logging period before the alarm and the period after the alarm can be specified.
1-Shot - Returns to logging setup at the end of the logging period
	Start -Starts Immediately, on Manual click or at selected Time of Day Stop - Stops on Manual click, at Time of Day, after specified Time Interval or after a specified number of Samples
Repeat - Repeats until manually returned to logging setup.
	Start - Starts N samples before Alarm, at Time of Day, after Time Interval or after N Samples Stop - Stops N samples after Alarm, at Time of Day, after Time Interval or after N Samples The logging repeats when the start condition is next detected.
Freeze
	A manual alternative to logging. Immediately freezes sampling allowing the display to be redrawn for clearer presentation. The information making up the screen display can then be dumped to disk.
File Formats
	All log files are text files and can be read with a text reading program such as Notepad. Files can be in :- Print Format - a heading on each page and in engineering units. Excel format - a heading at the beginning of the file and in engineering units. Data Format - raw data as measured with no engineering unit calculations included. Matlab Format - can easily be imported into Matlab programs for analysis.
