Live SPC from the plant floor
See quality problems on your lines while the shift is still running.
SCADA Lean is a lean, industrial-grade edge computer installed right in your plant. It connects to the PLCs you already run and streams their data securely to LSSI STATS, giving your team live control charts, capability and alerts. Fast to deploy, secure by design, and your lines keep running exactly as they do today.

01How it works
Your machines, one efficient edge device, and live results your team opens in any browser
The node reads your PLCs, keeps a local copy of every reading, and sends them over an encrypted outbound connection. Every reading is held safely on site until it is delivered.
Online · every reading reaches STATS Cloud within seconds
1 · Already at your plant
Machines and PLCs
The controllers that already run your lines, plus gauges and sensors. SCADA Lean connects read-only.
2 · We install
SCADA Lean node
A fanless industrial computer in your cabinet. It collects every reading and stores it securely on site.
3 · We operate
STATS Cloud
Stores every measurement and runs the statistics: control charts, capability, Gage R&R, AI explanations.
4 · Your people
Quality and CI teams
Live charts and reports in a browser, from the office, the floor or a phone. Alerts reach the right person.
02What changes
Quality decisions move from the weekly report to the moment the process drifts
01
Catch drift early
Alerts fire when a process starts to shift, while every part is still within specification.
02
Capability you can trust
Cpk calculated from every part produced, for a complete and reliable picture.
03
Find where variation comes from
Compare lines, shifts, crews, materials and products side by side.
04
Prove each improvement
Before-and-after results tied to each improvement project, ready for management review.

04For IT and OT security
Plant data reaches the cloud without opening your network
The design follows IEC 62443 zone-and-conduit principles. The node connects outward only, keeps each network fully separate, and reads your PLCs on a strict read-only basis.

R/O
read-only PLC access: your logic and setpoints stay exactly as you set them
Red: plant data to STATS Cloud. Blue dashed: the support tunnel, limited to the node itself.
- PLC access
- Read-only. It reads tags and registers, and every value, program and setpoint stays fully under your control.
- Network separation
- Two physical ports, one on the OT network and one uplink. IP forwarding is disabled, so each network stays fully isolated.
- Connection direction
- Outbound only: HTTPS on 443 to STATS, plus a Tailscale tunnel for support. Your firewall stays closed to inbound traffic.
- Remote support
- A WireGuard tunnel the node starts. Only named LSSI support staff, with SSO and MFA, limited to the node itself. Your IT team can require approval or switch it off.
- Encryption
- TLS 1.2 or later on every connection that leaves the plant.
- Identity
- Each node has its own credential, and a lost node can be revoked from the console. Users sign in to STATS with passkeys.
- Outages
- Data is held on the node through any uplink interruption and delivered in order, exactly once, when the connection returns.
- Your data
- Your production data belongs to you. Retention, export and deletion terms are set in the agreement.
05Deployment
Six steps from a site survey to the first capability study, mostly handled by our team
- 1
Step 1
Site survey
We review your PLC models, network layout and the characteristics that matter most to quality, with your IT team.
- 2
Step 2
Node preparation
We load the site settings and drivers for your equipment before the node ships.
- 3
Step 3
Install and connect
Your technician mounts the node and plugs in two network cables. It calls home and shows as healthy.
- 4
Step 4
Tag mapping
Each PLC tag is linked to a characteristic, with its units and specification limits.
- 5
Step 5
Live monitoring
Control charts update with each subgroup, and rule violations notify the right people.
- 6
Step 6
First capability readout
Cp/Cpk by line and shift, with an improvement project opened on the largest gap.

07FAQ
Questions plants ask us first
Is SCADA Lean safe for my machines?
Yes. The edge software is read-only by design: it reads tags and registers, and every value, program and setpoint stays exactly as your team set it. Your machines keep running as they do today.
What does my IT team need to configure?
Two outbound connections: HTTPS on port 443 to STATS Cloud, and a Tailscale tunnel our support team uses to maintain the node. Your firewall stays closed to inbound traffic.
How does it handle internet interruptions?
The node keeps reading and stores every measurement locally. When the connection returns, it delivers the backlog in order, and the cloud records each reading exactly once.
Which PLCs do you support?
OPC UA and Modbus TCP today, which covers most modern controllers and many gateways. EtherNet/IP (Allen-Bradley) and Siemens S7 drivers are next. Tell us your models and we confirm during the site survey.
Does it work with our existing SCADA or historian?
Yes. SCADA Lean runs alongside what you have. It reads the same tags and adds live statistics and capability on top, complementing your HMI.
How is it priced?
One annual subscription, sized by the number of PLCs you connect. It includes the devices, software, storage, alerts and support, plus a one-time setup per site. Gauges and instruments are included at no extra charge.
Who owns the data?
You do. Retention, export and deletion terms are written into the agreement.
How do we start?
With one line and success measures we agree on before the start. A one-hour working session with your operations, quality and IT leads is enough to plan the site survey.
Proposed starting point
Start with one line.
We agree the success measures together before the start. Bring a rough count of PLCs, the characteristics that matter most to quality, and an IT contact. A one-hour working session is enough to plan the site survey.
