Make history useful
The data is already there. Put it to work.
Give engineers and operators a route from InTouch LGH log files to answers.
Build repeatable reports
Get historical values into the tools your team uses to review production and quality.
Recover missing history
Use available InTouch logs as a source for a planned historian backfill workflow.
Keep operators in context
Use the Industrial Graphic option to query history from within InTouch HMI screens.
How it works
From daily logs to usable results.
A focused workflow for working with the history you already collect.
STEP 01
Find your history
Create an LGH File Place that points to the directory containing your InTouch history. Keep your source files available to the computer running the query.
- Select the LGH data directory
- Confirm access to the files
- Check the source time zone
STEP 02
Define your query
Choose the tags and time period relevant to your question. Narrow the scope to a batch, shift, or event rather than manually searching through daily logs.
- Choose the process tags
- Set the start and end time
- Review query settings
STEP 03
Review and export
Run the query, inspect the returned data, and export it for the next step in your workflow. Save the query when you expect to use it again.
- Review raw results
- Export Excel, CSV, or FastLoad
- Save a reusable query
Practical applications
Give yesterday’s data a useful next step.

Simple to use. Clear about the details.
Flexible options for file access, output formats, automation, integration, and deployment.
Files & access
Work with history where it lives.
The standalone application queries InTouch LGH history without requiring a running InTouch system. For remote files, configure an accessible location and the required Windows file permissions.
- Local history and accessible network locations
- LGH File Places organize data directories
- Confirm access under the account running automated jobs
Query & export
Get the right slice of process history.
Select tags and a time range, inspect results, then export to Excel, CSV, or AVEVA Historian FastLoad. Licensed queries support up to 1,024 tags and nearly 15 million values per query.
- Target a specific shift, batch, or incident
- Keep export format aligned with its destination
- Test real file sizes and query scope during evaluation
Automation
Repeat a query without rebuilding it.
Save a query as an .lghq file. Use Windows Task Scheduler, a batch file, or a suitable scheduling tool to run configured queries without manual interaction.
- Reuse saved query definitions
- Configure Advanced Query Settings
- Plan output locations and job permissions
InTouch integration
Give operators access inside the HMI.
The Industrial Graphic option embeds query functionality in AVEVA InTouch HMI windows. Operators can build, modify, and run queries without opening the standalone application. A bundle includes both options.
- Standalone application for desktop workflows
- Industrial Graphic for queries from HMI screens
- Verify the edition and InTouch version for your project
Time & compatibility
Keep the timing of your data meaningful.
Check time-zone and date-format settings before comparing records from different locations. LGH File Inspector supports configurable time formats, including UTC and offsets. Test the trial with history from your actual InTouch version.
- Review time-zone assumptions
- Choose the required output time format
- Confirm file compatibility before rollout
Evaluate with your own files. Confirm your InTouch version, permissions, time settings, and expected query size before deployment.

FAQ
Before you open your first file.
What is an LGH file?
An LGH file stores local historical process data logged by AVEVA InTouch, formerly Wonderware InTouch. Its proprietary format needs a compatible reader to turn recorded values into usable query results.
Does the standalone application need a running InTouch system?
No. The standalone application can query accessible LGH history without a running InTouch system. The Industrial Graphic option is designed to run within an InTouch HMI application.
What can I export?
Query results can be exported to Excel, CSV, or AVEVA Historian FastLoad. Choose the format that suits your reporting, analysis, or historian import workflow.
What are the free trial limits?
The trial allows 25 tags per query, 100 rows per query, and 25 total queries. It lets you evaluate exports and query automation. Contact Software Toolbox if you need help completing your evaluation.
Can queries run automatically?
Yes. Save a query and configure it to run through Windows Task Scheduler, a batch file, or another scheduling tool. The automation tutorial covers saved .lghq files and Advanced Query Settings.
Which edition should I choose?
Choose Standalone for desktop analysis and automated extraction, Industrial Graphic for queries within InTouch HMI screens, or the bundle for both. Confirm the user count and deployment requirements with Software Toolbox.
Does this replace a historian or guarantee compliance?
It provides access to existing InTouch history. It can support reporting and historian recovery workflows, but retention, validation, audit procedures, and regulatory compliance depend on your complete application and operating procedures.
What happens when support or a subscription expires?
A perpetual license continues operating if support coverage lapses. Updates and support depend on active coverage. A 90-day subscription is time limited; arrange renewal or conversion before it expires.
