1. Executive Summary

The Core Argument

Inductive Automation’s Ignition is a general-purpose, software-only SCADA / IIoT platform — a flexible “blank-canvas” toolkit for factory automation, utilities, smart buildings, and facility-wide control. QB Control is a SCADA-class platform purpose-built for bioprocessing, combining co-engineered hardware (QB Modules) and software with ~40 pre-built bioprocess services, a visual recipe engine, and built-in compliance modules. It deploys both on QB Edge (benchtop QB Modules) and on a standard industrial PC driving stainless-steel, PLC-based systems via OPC-UA.

The two products solve different problems. Ignition gives you maximum flexibility and expects you to build your bioprocess application — tags, screens, control logic, recipes — typically with a system integrator and external PLC hardware. QB Control ships the bioprocess application already built. The comparison is most relevant in lab-to-pilot bioprocessing (150 mL – 50 L benchtop, plus stainless-steel pilot/production via PLC), where Ignition’s generality becomes integration overhead and QB Control delivers a right-sized, turnkey alternative.

Key Finding

QB Control does not replace Ignition in all scenarios. It replaces Ignition where the requirement is bioprocess control rather than facility SCADA. For a 1–12 bioreactor lab or pilot line, building on Ignition means buying PLC hardware, paying a system integrator, standing up an external database, and custom-coding every control loop — then validating all of it as custom (GAMP 5 Category 5). QB Control delivers the same outcome turnkey, as configurable software (Category 4).

The Blank Canvas Problem

Ignition is a supremely capable toolkit — exactly right for refineries, water plants, smart buildings, and plant-wide MES, where control logic varies widely and unlimited protocol support matters. But that generality means every bioreactor deployment starts from an empty screen: someone must define every tag, code every pH loop and feed strategy, build every HMI screen, and wire every PLC. The flexibility you pay for in a factory becomes overhead in a development lab.

QB Control inverts this. The bioprocess application is already built and validated by design: select a service, assign a module, compose a recipe, run. Scientists operate it without SCADA or PLC expertise, and with its industrial-PC deployment path it now scales up to stainless-steel pilot and production cells that already have a PLC — without inheriting integrator cost or Category 5 validation. For bioprocess automation, Ignition is the blank canvas; QB Control is the finished, repeatable system.

  • I/O modules (analog, digital, temperature, pressure) — ~$500–3K per slot
  • Marshalling cabinet, terminal blocks, power supply, relays — ~$5K–15K
  • Cabling, conduit, installation labor — ~$5K–20K per bioprocess skid
  • External SQL database server (on-prem or cloud) + DBA time
  • Server OS management — patching, runtime, firewall, backups

QB Control Hardware Ecosystem (Included)

  • Auto-discovery over PoE eliminates manual device commissioning
  • Open sensors — Hamilton, Mettler Toledo, Levitronix at market price
  • New: for stainless-steel systems with existing PLCs, QB Control deploys on an industrial PC and integrates over OPC-UA — reusing field hardware instead of replacing it

4. Parallel Processing

Side-by-Side Comparison

Multi-bioreactor modelTypically one PLC per vessel + per-vessel SFC/scriptsEach bioreactor = independent Process with its own P&ID, alarms, recipe
Deployment (4 vessels, parallel)6–12 weeks (4 PLC programs + scripts + screens)2–5 days (centralized, parameter sets)

Re-sequence (e.g., change feed timing)Hours–days (edit PLC/SFC, test)Minutes (recipe UI)
Validation effortHigh (N PLCs = N validations)Low (one system, N parameter sets)

QB Control’s Parallel Processing Model

QB Control implements parallel processing through its System → Process → Batch hierarchy. Multiple Processes run within a system, each with an auto-generated P&ID, alarms, recipe, and batch recording. Multi-instance services instantiate the same control strategy across vessels; parallel recipe execution runs multiple recipes simultaneously; and QB Control adds sequential execution — batches queued with a Pending status and chained with auto-stop conditions for unattended campaigns. Each process carries its own per-process emergency stop (P-Stop).

Where Each Platform Excels

  • QB Control: no integrator to set up parallel operations, auto-generated P&ID per process, process/recipe import/export with device mapping for instant replication, and a conflict blockade that prevents batch collisions.
  • Ignition: scales without practical ceiling for facility-wide, multi-protocol deployments (utilities, buildings, MES), where its gateway architecture and unlimited licensing are genuine strengths.

Bioreactor OEMs (Sartorius, Applikon, Eppendorf)Custom OPC-UA integration per OEMOPC-UA connectors + service templates bridge OEM signals
Levitronix flow / Kern & MT scalesCustom integrationNative via QB Multisensor / QB Multiscale

Integration Philosophy Difference

Ignition: “We speak every industrial protocol; you (or your integrator) map each OEM’s tags into Ignition, build the screens, and script the logic. No pre-built bioreactor connectors — each integrator builds their own.”

QB Control: “We provide the hardware and the software. QB Modules natively connect Hamilton, Mettler Toledo, and Levitronix. For everything else there’s OPC-UA (with a dedicated connector), Modbus, MQTT, REST, SQL, and MTP — and we deploy on your existing PLC for stainless-steel systems. No integrator required.”

Honest Note

Ignition’s protocol breadth is genuinely broader — 100+ drivers including Allen-Bradley, Siemens, BACnet, and DNP3 — which is exactly why it dominates facility SCADA. QB Control is OPC-UA-centric by design: it covers the protocols bioprocessing actually needs and stays simple. For non-OPC legacy fieldbuses, Ignition wins; for bioreactor control, QB Control’s native hardware and pre-built services win.


6. Software Module Comparison

QB Control ships 18 software modules accessed through the Portal. Ignition ships a handful of core modules and sells the rest à la carte; bioprocess-specific capability is not among them and must be custom-built.

Conclusion: QB Control includes 18 bioprocess-optimized modules out of the box; Ignition includes a handful of generic core modules and requires custom development (or paid add-ons such as Sepasoft and Cirrus Link) for bioprocess capabilities.


7. Services Catalog & Rapid Deployment

QB Control’s Services Catalog — Bioprocess Content Ignition Doesn’t Have

A Service in QB Control is a pre-defined control action (the equivalent of a configured control loop) that directly commands hardware. Services come in two types: Autocomplete (execute a discrete task and close) and Continuous (run until explicitly stopped).

QB Control ships with ~40 pre-built service templates across 10 functional categories out of the box, with QB Filtration adding a tangential-flow filtration set (recently expanded):

CategoryExample ServicesCount
pH Controlby Base & CO₂, by Base & Acid, by One Pump, One Pump PID, pH PID6
Temperature Controlby TCU, by Heating Mat, by Steam & Water, Split Temp, Set Circulator Temp, Set Heating Mat Power6
Pump & FeedFeed, Autosubstrate, Set Pump Flow Rate, Set Centrifugal Pump RPM, Transfer Volume/Bolus, Gravimetric Feeding9
Gas ControlO₂ Control, Advanced O₂ Control, Set MFC Flow, Set Sparger Mass Flow4
Gas Volume DeliverySet Sparger Volume & Mass Flow1
SamplingAutomated Sampling, Sample by Syringe Pump, Sampler Cleaning3

LED & LightLED Control, LED Control Scheduler2
Core catalog (out of the box)~40
QB Filtration add-onFiltervig Control, Concentration Factor Logic, NWP Calculator, Breakthrough Detection, plus six new tangential-flow servicesexpanded

Service Profiles — Reusable Parameter Templates

QB Control’s Service Profiles save standardized parameter configurations as reusable templates, with grouped and atomic-style models, structured profile cards (e.g., PID tuning, Temperature Ramp, Operating Limits), and portable export/import to move complete profile sets between templates or environments.

Ignition: Zero Pre-Built Bioprocess Services

Ignition provides no pre-built bioprocess service templates. Every control strategy is custom-built using SFC (Sequential Function Charts), Jython scripting, and PLC logic. A single pH PID loop on Ignition requires defining tags, coding the control math, building the HMI, configuring historian logging, and validating — typically 2–3 weeks of integrator time per loop. For a 4-bioreactor system with multiple loops each, expect 6–9 weeks of from-scratch engineering with no reusability across vessels or projects.

Deployment Time Comparison

TaskIgnitionQB Control
Set up 2-bioreactor system (pH, temp, aeration, feed)6–8 weeks1–2 days
Add a 3rd bioreactor2–3 weeks (PLC, SFC, historian, UI)2–4 hours (add vessel, select profiles)
Change a pH setpointMinutes (tag edit)Seconds (UI)
Change a feed sequence (ramp 4h vs 2h)Hours–days (SFC edit, test, deploy)Minutes (recipe edit)
Switch pH strategy (CO₂+Base → Acid+Base)1–2 weeks (re-code, re-test, re-validate)5 minutes (swap service template)
Replicate a setup to a new bioreactorWeeks (new PLC, screens, historian)15 minutes (import/export + device mapping)

Conclusion: QB Control’s pre-built services eliminate 70–90% of the engineering time bioprocess automation requires on Ignition.


8. Recipe Engine

Overview

QB Control’s Recipe Module translates bioprocess protocols into executable workflows through three boards: Designer Board (create/edit), Batch Board (configure/execute), and Executions Board (monitor history). Ignition’s nearest equivalent is the SFC module — a programming tool, not a scientist’s tool.

8.1 Designer Board & the Unified Block Library

The Designer Board is a visual, drag-and-drop workspace for building process logic as a connected flow — no coding. QB Control consolidates the previous per-service blocks into a unified block library with grouping, descriptions, tooltips, and embedded in-app guidance:

BlockCategoryFunction
Start ServiceService ControlSingle configurable block; choose the service at configuration; supports Autocomplete and Continuous services
Stop ServiceService ControlExplicitly stop a continuous service later in the flow
Update Service InputsService ControlChange service inputs mid-execution (startup vs. runtime inputs kept separate)
Manual OperationOperationsPause for operator-driven action where supervised intervention is required
Variable / Update VariablesVariablesNamed values (boolean, text, number, time); update with increase / decrease / multiply / divide
TimerTimingShared timer with start / stop / pause / resume
Set Valve StateEquipment commandsCommand valve positions directly in the sequence
Conditional / Counter / PID / PolygonLogic & flowAND/OR conditions, loops, inline PID, piecewise-linear ramps
Split / MergeLogic & flowFork into parallel paths and join them back together

Authoring productivity: copy/paste of blocks, signal filtering, undo/redo, diagram export, and recipe import/export. The designer flags inactive recipes that should not be started as-is.

Recipe state lifecycle: Draft → Verified → Validated → Hold → Archived. Only Verified or Validated recipes can run in batches.

8.2 Batch & Executions Boards

  • Create batches and assign single or multiple recipes per batch; monitor and control in real time (stop, pause, resume)
  • Sequential batch execution with Pending queue + per-batch auto-stop (new); parallel execution across processes
  • Executions Board lists runs with status (During Execution, Paused, Hold, Pending, Completed, Failed, Aborted); filter by System/Process/Status; export list to CSV and recipe flow to PNG

8.3 Validation & Safety

  • The Validator verifies recipe logic before execution
  • Automated pre-start validations prevent batch collisions, unauthorized starts, and execution on disconnected hardware
  • Mandatory pre-execution checklist forces operators to verify critical lab elements (tubing, media) before start
  • License guard blocks creating/duplicating/importing recipes beyond the licensed limit
  • Runs hold or abort safely when a P-Stop or global E-Stop is active

Audit TrailCustom (SQL + scripting)✅ Immutable, exportable, cross-moduleQB built-in
Safe Position Logic (GMP)Custom PLC interlocks✅ Built-in — safe actuator states after restart/power cycleQB configurable feature

Compliance Value for QB Control

Ignition is a development platform: 21 CFR Part 11 conformance is achievable, but it is built and validated as custom software (Category 5) for each project — audit trail, e-records, and access control are your responsibility to implement in SQL and Jython. QB Control delivers audit trail, RBAC, records, calibration traceability, and Safe Position Logic as configurable features (Category 4), cutting validation effort by 50–70%.

Honest Compliance Caveat

QB Control’s 21 CFR Part 11 conformance is partial: electronic records, audit trails, access control, and user management are in place today, but electronic signatures are not yet implemented (roadmapped for Q3 2026). For workflows that require digital signatures on an active IND today, a custom-validated Ignition build or another route may be needed until QB Control’s e-signature release. Do not represent QB Control as fully 21 CFR Part 11 compliant.


10. Pricing, Licensing & TCO

The “Cheap Software, Expensive System” Reality

Ignition’s per-gateway licensing is modest and includes unlimited tags and clients — a genuine strength. But for bioprocess control the software license is the small part: you must add PLC hardware, I/O, a system integrator, an external SQL database, custom control code, and Category 5 validation. QB Control’s price is all-inclusive (hardware + software + bioprocess services) on a perpetual license.

Direct Cost Comparison

Key point: Ignition’s unlimited licensing is excellent value for facility SCADA. For bioprocess control, the license is a fraction of the true system cost — the PLC hardware, integrator labor, database, custom code, and Category 5 validation dominate. QB Control’s all-inclusive perpetual model is 50–70% lower over five years for a comparable bioreactor lab.

12. What QB Control Can Replace

Full Replacement Scenarios

1. Greenfield Lab Bioprocessing (150 mL–10 L) — Ignition + PLC build → QB Edge + QB Modules. Value: turnkey vs. integrator project, days not months, no custom code.

2. Parallel Small-Scale Fermentation / Screening — N PLCs + N SFCs on Ignition → QB Control multi-process with centralized orchestration and sequential auto-stop campaigns. Value: zero per-vessel PLC, auto-generated P&ID per process.

3. Stainless-Steel Pilot Cells with Existing PLCs (new) — Ignition gateway over PLC → QB Control on an industrial PC integrating the PLC via OPC-UA. Value: bioprocess-native supervisory control and recipes without building the application from scratch.

4. pH / DO / Temperature Control Loops — custom-coded Ignition PID loops + PLC I/O → QB Multisensor (Hamilton/MT) + QB Gasflow + QB Thermo + pre-built services. Value: native sensors, no PLC, no per-loop engineering.

5. Automated Sampling & Feed — custom SFC sequences → QB Selector Valve + QB Pump + recipe. Value: drag-and-drop, no scripting.

6. GMP Records, Audit Trail & Calibration — custom SQL/Jython build on Ignition → QB Audit Trail, Calibration, Users & Roles modules. Value: built-in Category 4 compliance.

Partial Replacement Scenarios

7. Ignition + PLC Bioprocess Modernization — keep facility Ignition for utilities/MES; move bioreactor control to QB Control; bridge via OPC-UA. Value: eliminate per-vessel PLC and custom code; cut validation.

8. Small-Scale GMP Production — QB Control provides partial 21 CFR Part 11 (records, audit trail, RBAC; e-signatures on roadmap). Value: lower validation burden, but plan an e-signature bridge until Q3 2026.


13. Where QB Control Creates Superior Value

13.2 Value Summary

Each pillar is detailed in the section noted; in brief, QB Control delivers:

  • Bioprocess content out of the box — ~40 pre-built services, Service Profiles, and a visual recipe engine vs. Ignition’s blank canvas (§7).
  • No integrator dependency — unbox, auto-discover, select services, run; zero integrator cost (§3, §7).
  • ~50–70% lower 5-year TCO — hardware included, no PLC, no external database, perpetual license (§10).
  • Built-in compliance — Audit Trail, Calibration, RBAC, and Safe Position Logic as configurable Category 4 features (§9).
  • Operational simplicity — browser-based, no external database, scientist-operable, single Health Monitoring dashboard (§3, §6).
  • Modern, open integration — native OPC-UA, MQTT, REST, SQL, MTP, and secure remote access; coexists with Ignition over OPC-UA (§5).

Honest Assessment of QB Control Limitations

  1. Not facility SCADA — QB Control controls bioprocesses, not buildings, utilities, or plant-wide lines.
  2. OPC-UA-centric — no native Allen-Bradley/Siemens/BACnet/DNP3; non-OPC legacy fieldbuses need a gateway.
  3. No MES — scheduling, lot tracking, and OEE require integration with an external system.
  4. No embedded scripting — the trade-off for Category 4 simplicity is configuration over custom code.
  5. No electronic signatures yet — 21 CFR Part 11 conformance is partial until Q3 2026.
  6. Scale ceiling — optimized for lab-to-pilot and early stainless-steel production, not 100K+ tag enterprise deployments.

15. Migration & Replacement Scenarios

Scenario A: Greenfield Lab (No Existing System)

Recommendation: QB Control. No integrator build, no PLC procurement — operational in days, all-inclusive, ~50–70% lower TCO than an Ignition+PLC build.

Scenario B: Ignition + PLC Bioprocess Lab Seeking Simplification

Recommendation: QB Control replacement. Replace the per-vessel PLC + custom SFC/Jython control with QB Control; keep facility Ignition; bridge via OPC-UA. Eliminates custom code and cuts validation.

Scenario C: Stainless-Steel Pilot Cell with an Existing PLC

Recommendation: QB Control on an industrial PC. Deploy on an industrial PC, integrate the PLC over OPC-UA, keep the field instruments. Value: bioprocess-native supervisory control and recipes without building the application from scratch.

Scenario D: Expanding Parallel Capacity

Recommendation: QB Control for new vessels. Add capacity with QB Modules and parameter sets instead of new PLCs and SFC programs; no impact on existing systems.

Scenario E: Facility Running Ignition for SCADA + MES

Recommendation: Complementary, not replacement. Keep Ignition for utilities, building automation, and MES; add QB Control for bioreactor control; connect over OPC-UA. “QB for bioreactors, Ignition for everything else.”

Scenario F: Academic / Research Institution

Recommendation: QB Control (full replacement) for bioreactors. Scientist-operable, all-inclusive, lower TCO, multi-user browser access; keep Ignition where campus-wide utilities/data are in scope.


16. Competitive Positioning Strategy

Positioning Statement

QB Control is not competing with Ignition as a SCADA platform — it is replacing the months of integrator work and PLC hardware you would otherwise spend building bioprocess control on Ignition. Ignition is the industry’s most flexible general-purpose SCADA toolkit, and for facility automation, utilities, and MES it is the right tool. But for bioreactor control that flexibility becomes overhead: external PLCs, system integrators, an external database, custom code for every loop, and GAMP Category 5 validation. When you are automating bioreactors — not factories — you do not need a blank canvas. QB Control ships ~40 pre-built bioprocess services, plug-and-play deployment in days, GAMP Category 4 validation (50–70% less effort), and 50–70% lower total cost of ownership. Keep Ignition for your facility. Use QB Control for your science.

Key Sales Arguments Against Ignition (for bioprocess)

Ignition RealityQB Control AdvantageEvidence
”The software is only $15K–30K”The system is $170K–410K once you add PLC, integrator, DB, validationQB all-inclusive $60K–85K (4 vessels)
“Ignition can build anything”That’s why every loop is custom code + Category 5 validationQB: ~40 pre-built services, Category 4
”We have a great integrator”That’s $30K–80K per engagementQB: self-service, $0 integrator
”Unlimited licensing”But the license excludes the PLC, I/O, and control logicQB includes hardware + services
”We need Python scripting”Custom code is a validation liabilityQB covers ~95% of workflows via configuration
”Ignition scales facility-wide”True — and complementaryRun QB for bioreactors, Ignition for facility, via OPC-UA
”Our team knows Ignition”They’ll validate QB in weeks, not monthsGAMP Cat 4 vs Cat 5

When NOT to Position Against Ignition

Do NOT position QB Control as a replacement when the client needs:

  • Facility-wide SCADA (utilities, WFI/CIP, HVAC, energy, building automation)
  • MES (production scheduling, lot tracking, OEE, material flow)
  • 100+ protocol / legacy fieldbus support (Allen-Bradley, Siemens, BACnet, DNP3)
  • Enterprise-scale analytics (multi-year, 100K+ tags, data lake / BI)
  • Deep custom scripting as a core requirement
  • A team with deep Ignition/PLC expertise and no interest in changing platforms

In these cases, position QB Control as complementary — bioreactors on QB Control, everything else on Ignition, connected via OPC-UA.

Overall: QB Control wins decisively for bioprocess control at lab-to-pilot/early-production scale, where its pre-built services, native hardware, visual recipe engine, built-in compliance, and ~50–70% lower TCO eliminate the integrator build Ignition requires. Ignition wins decisively for facility-wide SCADA, MES, multi-protocol, and enterprise-scale deployments — different problems, best solved by running both and connecting them over OPC-UA.


Recent QB Control Enhancements (current release)

The current QB Control release adds the capabilities referenced in this comparison (reflecting the current QB Control release):

  • Batch scheduling — recurring (daily / weekly / interval) or one-time run schedules per batch, with a calendar view, named schedules, skip-on-conflict handling, and matching audit-trail records.
  • Recipe portability — a recipe can be reassigned to a different process, automatically remapping its devices and services so a proven design moves between similar lines instead of being rebuilt.
  • Equipment changes from the P&ID — lab equipment can be added directly in the P&ID editor (auto-creating the matching inventory and process records), with freeform note elements and anchor-point piping connections; lab equipment can also be added or removed on already-deployed processes without creating a new process version.
  • Embedded OPC UA server — the OPC UA Connector can now run its own embedded OPC UA server, letting external OPC UA clients (e.g., MES, historians) read from QB Control directly.
  • Expanded catalog — six additional tangential-flow (cross-flow) filtration services and six new lab-equipment types (including cooling chamber, filter cassette, hollow-fiber filter, and vials holder).
  • Operations & safety — an alarm watchdog reconciling alarm state against live equipment values every 30 seconds; calibration that reserves the device during calibration (blocking conflicting operations); Protect / Interlock faceplate safeguards; audit-trail events filtered to the active license; and license-aware controls shown with explanatory tooltips.
  • Usability — an in-app Help section with guided walkthroughs and searchable content across every module; search across inventory tables; and Health Monitoring showing system start time and uptime.

Assumptions

To keep the comparison transparent and fair, the following assumptions and estimates were applied:

  • Third-party capabilities are interpreted from public vendor datasheets, brochures, manuals, and websites current at the analysis date. Where a capability was not clearly documented publicly, it is described as such (“not clearly documented,” “appears limited,” etc.) rather than asserted or denied.
  • Competitor pricing and total-cost-of-ownership figures are indicative estimates derived from public information and typical configurations — not vendor quotations or list prices.
  • QB Control reference figures are indicative, based on past quotations, and do not constitute a specific priced offer.
  • The comparison assumes a lab-to-pilot bioprocessing context (roughly 150 mL–50 L, plus stainless-steel pilot/production via PLC over OPC-UA); conclusions may differ at large multi-train production scale.
  • “QB Control” reflects the current released version at the analysis date; third-party products reflect the newest versions identified in public sources.
