Real-time SPC monitoring with zero configuration overhead
Here is a live demonstration of PIForge Smart SQC Pro running in AVEVA PI Vision:
Every capability is demonstrated live in AVEVA PI Vision.
Real-time SPC monitoring with zero configuration overhead
Watch your process data stream in live — Smart SPC/SQC Pro automatically calculates control limits, detects violations, and updates the status badge the moment something goes wrong. No scripts. No external tools. Just drag, drop, and monitor.
- Auto-calculates UCL, LCL, and CL from live PI tag data
- Status badge switches STABLE → WARNING → VIOLATION in real time
- Cpk updates continuously — green when capable, red when not
- Histogram and Gaussian curve build as data arrives
Instant alert when any value exceeds ±3σ
A single rogue data point crossing your control limit is all it takes for a batch to fail. Smart SPC/SQC Pro catches it the moment it happens — marking the violation directly on the chart and raising a VIOLATION alert before your operator even notices.
- Flags any point beyond ±3σ (sigma factor is configurable: 2, 3, or 4)
- Red violation circle appears on the exact data point
- VIOLATION badge shows total count — always visible at a glance
- Cpk turns red instantly when the process goes out of control
Detects when 2 out of 3 consecutive points exceed 2σ on the same side
A process shift rarely announces itself with a single extreme value — it creeps in as a subtle bias. Rule 2 catches this pattern early, raising a WARNING while you still have time to act, not after the damage is done.
- Detects 2/3 consecutive points above 2σ on the same side of the mean
- WARNING badge triggers before values ever cross the control limit
- N, M, and σ threshold fully configurable to match your process standards
- Works alongside Rule 1 — multiple rules fire independently
6 consecutive points rising or falling — a trend your process shouldn't have
A steady upward or downward trend in your process is a warning sign that something is changing — tool wear, temperature drift, raw material shift. Rule 5 identifies the pattern while it's still within limits, giving you time to investigate and correct.
- Detects 6+ consecutive points in a continuous rise or fall
- Trend violation markers appear as the pattern completes
- Configurable run length — tighten or loosen to match your process
- Pairs with Rule 4 (Bias) for complete drift detection coverage
Bias, Hugging, Oscillation, and Mixture patterns — all detected automatically
Most SPC charts only check Rule 1. Smart SPC/SQC Pro runs all 8 Western Electric rules simultaneously — catching the subtle patterns that ordinary charts miss entirely. Enable the rules your process needs, disable the ones you don't.
- Rule 4 (Bias): 9 consecutive points on one side of the mean
- Rule 6 (Hugging): 15 points within ±1σ — process too quiet
- Rule 7 (Oscillation): 14 alternating up/down — systematic variation
- Rule 8 (Mixture/Gap): 8 consecutive points beyond ±1σ — bimodal distribution
- All rules configurable independently — mix and match for your standard
Switch between 2σ, 3σ, and 4σ control limits without touching a formula
Not every process runs to 3-sigma. Tighten limits to 2σ for high-precision manufacturing, or widen to 4σ for naturally noisy processes. Change the sigma factor and watch UCL, LCL, and all zone bands update instantly — no recalculation needed.
- Sigma Factor: 2σ (tight) → 3σ (standard) → 4σ (wide)
- UCL and LCL lines move in real time as you adjust
- Cpk recalculates automatically to reflect the new limits
- Manual UCL/LCL override: map limits directly from another PI tag
Follow the PI Vision display time or pull any historical window you need
Smart SPC/SQC Pro works in three time modes. Display mode follows your PI Vision page time automatically. Duration mode fetches a fixed rolling window — last 8 hours, last 7 days. Custom mode lets you analyze any historical period down to the minute.
- Display mode: syncs with PI Vision page time — no extra configuration
- Duration mode: 8h, 24h, 7d — configurable rolling window with optional offset
- Follow Display Time: Duration window shifts as the PI Vision time advances
- Custom mode: set exact start and end dates for historical SPC analysis
Color bands, histogram, data badges — toggle each independently
Every operator and every display has different needs. A control room wall screen needs a clean trend line. An engineer's workstation benefits from the full histogram and zone bands. Smart SPC/SQC Pro lets you configure exactly what's shown — and it persists per symbol.
- Color Bands: shade zones A/B/C/D (±1σ / ±2σ / ±3σ) for instant visual context
- Histogram + Gaussian curve: see your data distribution alongside the trend
- Data Badges: pin value labels on key points — first, last, and violations
- Limit Line Style: solid or dashed — adapt to your display background
Every color configurable — trend line, limits, zones, background
Whether your control room uses a dark theme, a light theme, or your company's brand colors, Smart SPC/SQC Pro adapts completely. Change the trend line color, limit line color, zone band intensities, and background — all in the configuration panel, all reflected instantly.
- Trend line color: adapt to any display background
- Limit line color: high-visibility red by default, fully overridable
- Zone colors: tune the opacity of each sigma band independently
- Background and text color: dark theme, light theme, or anything in between
Setting up PIForge Smart SQC Pro is quick and straightforward. Follow these steps:
Extract the downloaded ZIP package. You will find HTML, JS, CSS/SVG, and image files. Copy these files to your PI Vision server's extension folder:
%PIHOME%\Scripts\app\editor\symbols\extTypically, this path translates to:
C:\Program Files\PIPC\PIVision\Scripts\app\editor\symbols\extWindows blocks downloaded files by default. If you skip this step, the symbol will silently fail to load in PI Vision.
- Right-click the
.jsand.htmlfiles you copied on the server. - Select Properties from the context menu.
- On the General tab, look for the security warning at the bottom: This file came from another computer and might be blocked to help protect this computer.
- Check the Unblock box, then click Apply and OK.
- Repeat this for all files in the package.
- Log in to your PIForge Dashboard and go to My Licenses to copy your License Key (format:
XXXX-XXXX-XXXX-XXXX). - Open PI Vision, add the symbol to a display.
- Click the Format Symbol (⚙) configuration panel.
- Paste your key into the License Key field and click Activate.
In PI Vision, go to Help → About to verify your version number.
| PI Vision Version | Smart SQC Pro Support | Notes |

- Verify the files are copied to the correct
extdirectory on the PI Vision server (not your local machine). - Perform a hard browser refresh:
Ctrl + Shift + R. - Ensure all files are unblocked (see step 2 of the Installation Guide).
- Open Browser DevTools (
F12) and check the Console tab for red errors. - Verify the license key has no extra spaces.
- Try restarting IIS on the PI Vision server. Run this command in an Administrator command prompt:
iisreset
- If you run into issues, copy your license key and contact us at contact.piforge@gmail.com for assistance.
