Wintriss LETS - How LETS Works
Communications With The Machines
Your machine controls send real-time production information to LETS using your existing Ethernet.
For stamping press applications, the Wintriss SmartPAC 1 can be made Ethernet compatible by adding our
serial-to-Ethernet converter.
The SmartPAC 2 and
LETS Machine Interface (LMI) already have
built-in Ethernet capability.

Machines such as welders, injection molding machines, etc., can be connected to LETS using the
LETS Machine Interface (LMI).
We can help you to determine what data you need to collect from each
machine and recommend a range of solutions.
Here is a description of the software components that make up a LETS Installation:
Data Logger
The data logger is the "engine" that drives the data collection process. It retrieves the
data from each control, sorts it, and puts it into the database. LETS uses Rockwell’s
FactoryTalk Transaction Manager – the industry standard data logger/transaction manager. It
is FactoryTalk’s powerful interfacing capabilities that enables us to communicate with many different
types of controls including PC's, PLC's (Programmable Logic Controllers), and even proprietary
controls - provided the vendor supplies us with the communication protocol.
The Database
The database stores all of the production information and "feeds" the LETS Report Manager, the Report Server,
and the Factory Viewer. LETS uses Microsoft’s SQL Server Version 2008 database.
Microsoft SQL Server is the most widely used database in the world. The Microsoft SQL
database is highly scalable – it can easily grow with your needs. If you need to share data
with other software, chances are good that someone has written a SQL Server interface.
The Factory Viewer
The LETS Factory Viewer allows you to see at a glance the status of your entire factory.
The overview screen shows the status of each machine (green when running, red if stopped, and yellow
for a tool change) as well as the parts count, current tool, and estimated time until job completion.
By clicking on the machine name, you can bring up more detailed job and downtime
information. Best of all, the Factory Viewer runs in your web browser; there is no need to
install client software. Click here for a self-guided demo of the Factory Viewer.
The LETS Reporting Interface is built into the database and is fully accessible through the Factory Viewer.
The Report Interface allows you to configure reports by date range, shift, machine, tool/part, and/or
operator. For example, you could specify that you want a report showing production data for
4 of your machines, while they were making 10 specific parts, being run by 5 selected operators, on
third shift. Once configured, you can save the settings as a new report. You can create as
many new reports as you wish - there is no limit to the number of report configurations that you can store.
The Report Generator runs on the server, allowing multiple users
to configure reports simultaneously.
The Report Server
The Report server controls the automatic distribution of the reports.
Reports can be sent via email to any recipients that you chose, or posted as links into the database that can be viewed in a web
browser by anyone with appropriate access. Also, once you've set up the distribution schedule,
the Report Manager will automatically generate and distribute the reports.
LETS Factory Viewer
The "Tools" page in the Factory Viewer shows a list of all of your tools, along with their status -
Running, Down, or Available. LETS also keeps an accurate total cycle count (with preset)
for your tooling - even when tooling are run in multiple machines. If a tool has exceeded its total
hits preset, the background for the tool listing turns red.
