QB Control vs DeltaV Comparison
DeltaV vs. QB Control
Comparative Analysis & Replacement Strategy
1. Executive Summary
The Core Argument
Emerson DeltaV is a full-scale DCS (Distributed Control System) designed for enterprise-level process manufacturing across oil & gas, chemicals, and pharma. QB Control is a SCADA-class browser-based platform designed specifically for modular liquid handling and bioprocessing — from lab bench to pilot scale.
These are fundamentally different products serving overlapping but distinct markets. The comparison is most relevant in upstream bioprocessing at lab and pilot scale (1 L – 50 L bioreactors, parallel fermentation, sampling, media preparation), where DeltaV is heavily over-engineered and QB Control provides a right-sized, cost-effective alternative.
Key Finding
| Scenario | QB Control Replaces DeltaV? | Value Driver |
|---|---|---|
| Lab-scale bioprocessing (1–10 L) | ✓ Full replacement | 90% cost reduction, days vs. months setup |
| Pilot-scale upstream (10–50 L) | ✓ Full replacement | 70-80% cost reduction, modular flexibility |
| Parallel fermentation (multi-vessel) | ✓ Strong replacement | Plug-and-play parallel, no SI needed |
| Process development & DoE | ✓ Superior alternative | Faster iteration, lower barrier to entry |
| Single-use bioprocessing | ✓ Strong replacement | Native SU support, no legacy baggage |
| GMP production (>200 L) | ◐ Partial / complementary | QB Control for monitoring; DeltaV for full control |
| Continuous manufacturing | ✗ Not a replacement | DeltaV's MPC & PAT capabilities required |
| Enterprise-wide multi-site DCS | ✗ Not a replacement | Different product category entirely |
2. Platform Philosophy Comparison
Fundamental Architecture Difference
| Dimension | DeltaV | QB Control |
|---|---|---|
| Product Category | DCS (Distributed Control System) | SCADA-class browser-based platform |
| Design Philosophy | Enterprise-first, top-down | Modular-first, bottom-up |
| Target Scale | Plant-wide (250 mL – 20,000+ L) | Lab-to-pilot (250 mL – 50 L, extensible) |
| Approach to Hardware | Proprietary controllers + 3rd-party instruments | Own modular hardware (QB Modules) + open sensors |
| Software Delivery | Installed on Dell workstations (Windows) | Browser-based (any device, any OS) |
| Configuration Model | IEC 61131-3 programming + ISA-88 batch | Visual drag-and-drop + recipe designer (no coding) |
| Deployment Time | Weeks to months (requires SI) | Days (plug-and-play) |
| Vendor Strategy | Proprietary ecosystem (lock-in) | Open ecosystem (no lock-in) |
| GAMP Classification | Category 5 (custom software) | Category 4 (configurable software) |
What This Means for the Client
DeltaV assumes the client needs enterprise-grade process control with full ISA-88 compliance, MPC, and integration into plant-wide SCADA/MES/ERP systems. This assumption is correct for large production facilities but creates massive over-engineering for:
R&D laboratories running 1–10 L bioreactors
Process development teams doing DoE (Design of Experiments)
Pilot-scale facilities with 10–50 L vessels
Academic research labs
CDMOs running parallel small-scale campaigns
Cosmetics and food & beverage formulation labs

| Cross-Batch Comparison | DeltaV Batch Analytics | QB Graphs multi-parameter overlay + CSV export for external analysis |
| Technology Transfer | ISA-88 recipe structure enables lab→production migration | Process Configuration Import/Export for replication across QB Control installations |
| Campaign Management | Dedicated Campaign Manager module | Recipe Executions Board with batch lifecycle management |
System defines the physical resources (devices, services, equipment, media)
Multiple Processes can be defined within a system, each with its own:
P&ID (auto-generated, drag-and-drop customizable)
Alarm configuration
Recipe assignment
Batch recording
Reports
Multi-instance services allow the same service type to be instantiated across multiple processes
Parallel Recipe Execution — multiple recipes run simultaneously across different processes
Process-level isolation — each process operates independently with its own control loop
Where QB Control Excels in Parallel Processing
No system integrator needed to set up parallel operations
Visual P&ID per process — auto-generated from configuration, not manually drawn
Process Configuration Import/Export — replicate a proven setup to new bioreactors instantly
Multi-user concurrent access — different operators can monitor/control different processes simultaneously from different devices
Lower incremental cost — adding a parallel bioreactor = adding QB Modules + license expansion (not buying new controllers, workstations, or SI engagement)
Where DeltaV Excels in Parallel Processing
Higher vessel count at production scale (32+ bioreactors)
More sophisticated resource arbitration (Batch Executive for shared CIP/SIP)
ISA-88 full compliance with standardized terminology and structure

5. Multi-Vendor Equipment Integration
Protocol Support Comparison
| Protocol | DeltaV | QB Control |
|---|---|---|
| OPC UA | Native (App Stations, PK, EIOC); OPC DA limited to 32-bit | Supported for industrial connectivity |
| Modbus | Native (TCP on PK/VIM2) | Supported (TCP and RTU via QB Multisensor) |
| MQTT | Not native (requires gateway) | Native — IoT real-time streaming |
| REST API | Not native | Native — modern web integrations |
| SQL (JDBC/ODBC) | Limited/custom | Native — direct database access |

| Mettler Toledo Scales | Via analog/serial | Native — any MT-SICS compatible scale via QB Multiscale |
| Kern Scales | Custom integration | Native — PKP series via QB Multiscale |
Integration Philosophy Difference
DeltaV: "We provide the control platform; you bring 3rd-party instruments and we integrate them via industrial protocols (HART, Fieldbus, OPC). Pre-engineered integrations exist for select OEM partners (Sartorius, Applikon, Cytiva) but still require significant engineering."
Native sensor support — Hamilton and Mettler Toledo probes connect directly to QB Multisensor via Modbus RS485. No HART adapters, no Softing gateways, no Foundation Fieldbus complexity
Modern protocols — MQTT, REST API, SQL are native. DeltaV requires custom gateways for these
No OPC 32-bit limitation — DeltaV's OPC DA Server only accepts 32-bit clients. QB Control uses OPC UA natively
No Foundation Fieldbus headaches — DeltaV users consistently complain about FF segment losses and complexity. QB Control doesn't use FF at all
Auto-discovery vs. manual commissioning — plug in a QB Module and it appears in the inventory automatically
DeltaV's Integration Advantage
Pre-engineered OEM kits for Sartorius Biostat STR Gen 3 (80% faster integration) and Applikon V-Control
MTP (Module Type Package) support for NAMUR-standard modular manufacturing
Broader industrial protocol support for legacy plant integration (Foundation Fieldbus, PROFINET S2 redundancy)
Plant-wide integration capability — connects to MES, ERP, LIMS at enterprise level
Proven at production scale with complex, multi-vendor installations
6. Software Module Comparison

| Backup | System backup utility | Backup & Export (scheduled, selective, integrity verification) | Comparable |
| License Management | LDK dongle or softkey | License (feature-based, device-based, time-based, online/offline) | QB more flexible licensing |
| MPC / Advanced Control | DeltaV PredictPro (economic optimizer) | ✗ Not available | DeltaV wins |
| PAT Integration | DeltaV Spectral PAT (embedded) | ✗ Not available | DeltaV wins |
| Digital Twin | DeltaV Mimic 6.LTS | ✗ Not available | DeltaV wins |
| MES | Syncade (electronic batch records) | ✗ Not native (REST API integration point) | DeltaV wins |
| AI/ML | DeltaV Neural, Revamp, AI portfolio | ✗ Not available | DeltaV wins |
| Edge Computing | DeltaV Edge Environment 2.0 | QB Edge (runs QB Control locally) | Different approach, both valid |
7. Services Catalog & Rapid Deployment
One of QB Control's most powerful advantages over DeltaV is the Services Catalog — a library of pre-built, parameterized service templates that can be loaded and executed within minutes. This fundamentally changes how quickly scientists can deploy and modify bioprocess control strategies.
What Are Services?
In QB Control, a Service is a pre-defined control action that directly commands hardware. Services are the atomic building blocks of process automation — they bridge the gap between the software logic (Operations) and physical hardware (QB Modules). Services come in two types:
Autocomplete Services — execute a discrete task and close automatically (e.g., Transfer volume by pump, Add gas volume by Mass Flow Controller)
Continuous Services — run indefinitely until explicitly stopped (e.g., Set Agitator Speed, Temperature Control by TCU, pH Control by Base and CO2)
The Complete Services Catalog (v1.9)
| Category | Services | Count | Types |
|---|---|---|---|
| pH Control | pH Control by Base & CO₂, pH Control by Base & Acid, pH Control by One Pump, pH Control One Pump PID, pH PID Control, PID Reference | 6 | Continuous |
| Temperature Control | Temperature Control by TCU, Temperature Control by Heating Mat, Temperature Control by Steam & Water, Split Temp Control, Set Circulator Temperature, Set Heating Mat Power | 6 | Continuous |
| Pump & Feed Control | Feed Service, Autosubstrate, Set Pump Flow Rate, Set On/Off Pump, Set Centrifugal Pump RPM, Transfer Volume by Pump, Transfer Bolus Mass, Transfer Bolus Volume, Gravimetric Feeding by Peristaltic Pump | 9 | Continuous + Autocomplete |
| Gas Control | O₂ Control, Advanced O₂ Control, Set Mass Flow Controller Flow, Set Sparger Mass Flow | 4 | Continuous |
| Gas Volume Delivery | Set Sparger Volume & Mass Flow | 1 | Autocomplete |
| Sampling | Automated Sampling, Sample by Syringe Pump, Sampler Cleaning | 3 | Continuous + Autocomplete |
| Stirring & Agitation | Stirring Service, Set Agitator Speed | 2 | Continuous |
| Foam Control | Foam Control, Foam Control by Antifoam Reagent | 2 | Continuous |
| Valve Control | Set Selector Valve Position, Set Valve Position | 2 | Continuous |
| LED & Light Control | LED Control, LED Control Scheduler | 2 | Continuous |
| Total | 37 | 32 Continuous + 5 Autocomplete |
Service Profiles — Reusable Parameter Templates
Available Profile Types:
pH Control & pH PID Control profiles
Temperature Control & Heating/Cooling Control profiles
Gas Flow Control profiles
Stirring profiles
Foam Control profiles
Profile Creation Example (pH Control):
Each profile stores precise operational parameters: pH Tolerance, Base Amount, Base Flow Rate, CO2 Flow Time, CO2 Flow Rate, Delay Time — all saved under a named profile that can be applied to any process in seconds.
How Services Transform Experiment Deployment
| Workflow Step | DeltaV Approach | QB Control with Services Catalog |
|---|---|---|
| Define control strategy | Write IEC 61131-3 code or configure complex function blocks | Select service template from catalog (e.g., "pH Control by Base and CO2") |
| Set parameters | Enter values in Control Studio, requires trained engineer | Load a saved Service Profile or enter values in visual form |
| Change control logic | Reprogram function blocks, re-validate | Swap service template (e.g., switch from "pH by Base & CO2" to "pH by Base & Acid") — minutes, not days |
| Deploy to process | Commission, test, validate — weeks | Add service to process definition, appears in Recipe Designer — minutes |
| Try different strategy | New engineering engagement | Select different service from catalog, apply different profile — instant |
The Services + Recipe Integration Advantage
Services are the execution layer within QB Control's Recipe system. When building a recipe in the Designer Board , the available Services panel shows only services defined in the assigned process — ensuring safety and correctness. This means:
Load services from catalog → define which control strategies are available for a process
Build recipes visually → drag services into the workflow alongside Operations (Wait, Conditional, Split, Merge, PID, Polygon, Counter, Manual Operation)
Execute with one click → the Batch Board tracks every service execution in real-time
Switch strategies instantly → change the service template (e.g., from PWM-based foam control to PID-based) without rebuilding the recipe
This is a capability DeltaV simply cannot match at the lab/pilot scale. DeltaV requires engineering effort (IEC 61131-3 programming, commissioning, validation) for every control strategy change. QB Control makes it a catalog selection.
DeltaV vs. QB Control: Time-to-Deploy for Experiment Strategy Changes
| Scenario | DeltaV Time | QB Control Time | QB Advantage |
|---|---|---|---|
| Switch pH control from CO2+Base to Acid+Base | 1–2 weeks (reprogram, test, validate) | 5 minutes (swap service template) | ~200× faster |
| Add foam control to an existing process | 1–2 weeks (new I/O, programming, commissioning) | 10 minutes (add service from catalog + connect foam sensor) | ~150× faster |
| Change temperature control from setpoint to ramp | Days (modify function blocks) | 2 minutes (change service parameters or swap template) | ~500× faster |
| Deploy a completely new experimental strategy | 4–8 weeks (full engineering cycle) | 1–2 hours (select services, build recipe, validate) | ~200× faster |
| Replicate a proven setup to a new bioreactor | 2–4 weeks (copy, adapt, re-validate) | 15 minutes (Process Import/Export + Service Profiles) | ~100× faster |
8. Recipe Engine — Designer, Batch Board & Executions Board
Overview
The Recipe Module is the core automation engine of QB Control. It translates complex biotechnological protocols into executable digital workflows by combining Operations (logic) and Services (hardware actions). The Recipe system operates through three integrated boards:
8.1 Recipe Designer Board
The Designer Board is a visual, drag-and-drop workspace for building process logic using a directed acyclic graph approach.
Available Operations (Logic Blocks):
| Block Type | Category | Function |
|---|---|---|
| Start | Standard | Begin recipe execution |
| Wait | Standard | Time-based pause |
| End | Standard | End recipe execution |
| Stop | Standard | Terminate execution path |
| Conditional | Advanced | Evaluate real-time process variables (e.g., trigger action if pH > threshold) |
| Wait Until | Advanced | Pause until a sensor condition is met |
| Counter | Advanced | Loop control with iteration count |
| Polygon | Advanced | Piecewise linear mapping (X→Y with configurable points) — for ramps, profiles |
| PID | Advanced | Built-in PID controller block for inline control |
| Split | Advanced | Fork into parallel execution paths |
| Merge | Advanced | Join parallel paths back together |
| Manual Operation | Advanced | Pause for human confirmation (physical sampling, visual inspection) |
Available Services (Hardware Actions):
All 37 service templates from the Services Catalog (filtered to those defined in the assigned process)
Services appear as draggable blocks categorized as Autocomplete or Continuous
Key Design Features:
Undo/Redo visual history for all design changes

Configure Parameters per block (setpoints, wait durations, thresholds)
Export as Image for compliance documentation and peer review
Recipe Versioning with status lifecycle: Draft (Yellow) → Verified (Blue) → Validated (Green) → Archived (Red)
8.2 Batch Board
The Batch Board provides a high-level overview of all active and historical batch executions:
Status Indicators: During Execution (Blue), Completed (Green), Aborted (Red), Paused (Yellow)
Audit Trail: Logs Execution Start, Execution Finish, and Started By user ID for every batch
Filtering: By Systems, Processes, Statuses, date range
Export to CSV for external reporting or audit
Detailed Execution View: Click the information icon ("i") next to any batch to access the Recipe Status dashboard showing:
Step-by-step execution status per block (Completed, Failed, Paused, Aborted)
Failure & abort information with reasons
Real-time progress tracking (total, completed, in-progress, pending, failed)
Export as Image — download the entire execution flow as a graphic for reports
8.3 Pre-Execution Safety
Device Alarms verified
Hardware State confirmed (all devices idle)
Lab Equipment & Media confirmed prepared
Wetware Integrity checked (tubing, filters, fluidic connections)
Resource Conflict Blockade — if services in the recipe are already executing, the system blocks the start and displays a notification
8.4 Recipe Engine vs. DeltaV Batch — Detailed Comparison
| Capability | DeltaV Batch | QB Control Recipe Engine |
|---|---|---|
| Workflow design | IEC 61131-3 + ISA-88 procedural model (requires trained engineer) | Visual drag-and-drop Designer Board (no coding) |
| Parallel execution | Batch Executive with unit arbitration | Split/Merge blocks for parallel paths within a recipe |
| Conditional logic | Sequential Function Charts (SFC) with transitions | Conditional blocks evaluating real-time sensor data |
| Human-in-the-loop | Manual phase with operator prompts | Manual Operation block — pauses for physical confirmation |

What this means for the client:
50-70% reduction in validation effort compared to DeltaV
Faster time to GMP-ready operation (weeks vs. months)
Lower CSV (Computer System Validation) cost
Simpler change management — configuration changes, not code changes

| ~74% lower TCO |
Licensing Model Comparison
| Aspect | DeltaV | QB Control |
|---|---|---|
| Model | I/O count + Feature Descriptor Modules (FDM) + per-workstation; recurring fees | Perpetual license (one-time purchase) — feature-based + device-based + system/process-based |
| License Type | Subscription or term-based (annual renewal required) | Perpetual — buy once, use forever; no recurring license fees |
| Support | Included in subscription or sold as separate Guardian Support contract | Paid separately — tiered support levels (Basic, Standard, Premium) chosen by client |
| Additional Features | Add features = add FDM cost (additional license modules) | Additional features / hardware modifications priced upon client request — transparent, quote-based |
| Lock-In | Proprietary dongle ($50K–$300K); tied to Emerson hardware | Software license key; not tied to specific hardware vendor |
| Scalability | Add I/O = add license cost; add features = add FDM cost | Add devices/processes = license tier upgrade (one-time) |
| Subscription Option | DeltaV Flex System (1/3/5-year terms, up to 40% savings) | Not required — perpetual is the primary model |
| Transparency | No published pricing; all custom quotes | Tiered pricing structure (license-level specific capabilities) |
| Hardware Dependency | Dell-only workstations; Emerson-only controllers | Any browser-capable device; QB Edge is the only required hardware |
Licensing Model — Key Client Value
The perpetual licensing model is a significant differentiator for QB Control:
No recurring license fees — once purchased, the software license does not expire. This eliminates the annual licensing burden that DeltaV imposes ($20K–$50K/year for typical lab setups)
Paid support is optional and tiered — clients choose the support level that matches their needs (from basic email support to premium 24/7 with SLA). No forced bundling
Additional capabilities on request — new features or hardware modifications are priced transparently upon client request, not hidden behind opaque FDM modules
Predictable budgeting — the one-time license cost plus optional support makes QB Control's total ownership cost highly predictable, unlike DeltaV's layered subscription + FDM + Guardian Support model
No "license hostage" risk — DeltaV users report that letting licenses lapse can lock them out of their own systems. QB Control's perpetual model eliminates this risk

DeltaV PID loops with HART/Fieldbus sensors → QB Multisensor (Hamilton/MT probes) + QB Gasflow + QB Thermo + QB Control services
Value: Native sensor integration, no adapters, no Fieldbus complexity
- Process Development & DoE
DeltaV configuration + engineering → QB Control process import/export + rapid reconfiguration
Value: Change setups in minutes, not weeks. Run different configurations on parallel vessels simultaneously
- Single-Use Bioprocessing
DeltaV with Sartorius STR Gen 3 → QB Modules with SU pump heads, SU pressure sensors
Value: More vendor flexibility, lower cost, simpler setup
Partial Replacement Scenarios
- Pilot-Scale Upstream Processing (10–50 L)
DeltaV may still be needed for complex cascade control or MPC optimization
Value: QB Control as primary platform with OPC UA bridge to DeltaV for advanced control functions
- Small-Scale GMP Production
May need additional qualification documentation compared to DeltaV
Value: Lower validation burden (GAMP 5 Category 4), but may need to demonstrate equivalence
13. Where QB Control Creates Superior Value
Value Proposition #1: Time-to-Process
| Metric | DeltaV | QB Control | Improvement |
|---|---|---|---|
| System setup | 14+ weeks (vendor selection → validation) | < 1 week (unbox → first experiment) | 93% faster |
| Add a bioreactor | 2-4 weeks (engineering, commissioning, validation) | < 1 day (plug in modules, configure process) | 95% faster |
| Recipe modification | Hours (requires qualified engineer) | Minutes (visual drag-and-drop) | 90% faster |
| New process configuration | Days-weeks (SI engagement possible) | Hours (import/export or visual configuration) | 80% faster |
Value Proposition #2: Total Cost of Ownership
~74% lower 5-year TCO for a 6-bioreactor lab setup ($185K vs. $720K)
Perpetual software license — no recurring license fees, ever
Zero system integrator cost — self-service plug-and-play
Zero dedicated workstation cost — use any existing device
50-75% lower validation cost — GAMP 5 Category 4 vs. Category 5
Paid support is optional and tiered — client controls ongoing costs
Value Proposition #3: No Vendor Lock-In
Open sensors — Hamilton, Mettler Toledo, Levitronix at market price
Open consumables — choose your tubing, membranes, filters from any vendor
No proprietary hardware dependency — QB Modules are the only specialized hardware, and they're designed to be modular and replaceable
Standard protocols — OPC UA, REST API, SQL, MQTT for any integration
Value Proposition #4: Operational Simplicity
Browser-based — no client installation, no IT tickets, no OS compatibility issues
Auto-discovery — plug in a device, it appears in the software
Visual recipe designer — no coding, no IEC 61131-3 programming
Multi-user concurrent access — process engineer, operator, QA reviewer all work simultaneously
GAMP 5 Category 4 — configurable, not custom — simpler change management
Value Proposition #5: Services Catalog — Instant Strategy Deployment
37 pre-built service templates across 10 functional categories covering every core bioprocess control need
Load & execute in minutes — select a service from the catalog, configure parameters, deploy
Service Profiles — save proven parameter sets as reusable templates across processes
Switch control strategies instantly — swap pH control from CO2+Base to Acid+Base in 5 minutes (vs. 1-2 weeks on DeltaV)
Multiple control logic types per service — PWM, PID, Ramps, setpoint, gravimetric, event-driven
Seamlessly integrated with Recipe Designer — services appear as draggable blocks in the visual workflow builder
DeltaV has no equivalent — changing control strategies requires IEC 61131-3 reprogramming and re-validation
Value Proposition #6: Modern IT Architecture
REST API for LIMS/MES/ERP integration (DeltaV lacks native REST API)
MQTT for IoT data streaming (DeltaV requires gateways)
SQL for direct data access (DeltaV requires custom connectors)
LDAP/AD for single sign-on (DeltaV relies on Windows domain integration)
VPN/WireGuard for secure remote access
14. Gaps & Limitations — Where DeltaV Still Wins
DeltaV Capabilities Not Available in QB Control
| Capability | DeltaV | QB Control | Impact |
|---|---|---|---|
| Model Predictive Control (MPC) | DeltaV PredictPro (40 inputs, 80 outputs, economic optimizer) | Not available | High — critical for advanced process optimization |
| PAT Integration | DeltaV Spectral PAT (embedded chemometric models) | Not available | High — required for continuous manufacturing |
| Digital Twin / Simulation | DeltaV Mimic 6.LTS | Not available | Medium — useful for operator training and process optimization |
| ISA-88 Full Compliance | Best-in-class batch engine with formal certification | Follows batch concepts but not formally ISA-88 certified | Medium — important for large-scale GMP production |
| MES Integration | Syncade (native electronic batch records, ERP/LIMS/CMMS integration) | REST API integration point (no native MES) | Medium — required for enterprise manufacturing |
| AI/ML | DeltaV Neural (virtual sensors), Revamp (automated config) | Not available | Medium — growing importance |
| Production Scale (>200 L) | Proven at 20,000+ L production bioreactors | Not designed for this scale | High — different product category |
| Enterprise Multi-Site | Multi-site DeltaV deployments with enterprise historian | Single-site, single-QB Edge (networkable) | High — different product category |
| SIL-rated Safety | Safety Instrumented System (SIS) integration | Not SIL-rated | Medium — required for hazardous processes |
| Foundation Fieldbus | Native support | Not supported | Low — declining protocol, often problematic |
| Campaign Manager | Dedicated batch campaign planning | Recipe Executions Board (simpler) | Low-Medium — DeltaV more sophisticated |
| Batch Analytics | Cross-batch statistical analysis and fault prediction | CSV export for external analysis | Medium — DeltaV built-in; QB requires external tools |
Honest Assessment of QB Control Limitations
Scale ceiling — QB Control is optimized for lab-to-pilot (up to ~50 L). Production-scale bioprocessing still requires DeltaV or equivalent DCS
No MPC — advanced control strategies (multivariable predictive control with economic optimizer) are not available
No PAT — inline spectral analysis and chemometric models are not embedded
No digital twin — simulation and operator training capabilities are absent
No native MES — electronic batch records require integration with external MES
ISA-88 formal certification — while QB Control follows batch processing concepts, it is not formally ISA-88 certified, which may be required by some large pharma companies
Limited to liquid handling — QB Control does not address gas-phase, solid-phase, or complex hybrid processes
15. Migration & Replacement Scenarios
Scenario A: Greenfield Lab (No Existing DeltaV)
Recommendation: QB Control
New lab setup from scratch = no migration, no legacy
80% cost savings vs. DeltaV
Operational in days, not months
Scenario B: DeltaV Lab Seeking Modernization
Recommendation: QB Control replacement
Replace DeltaV Discovery or DeltaV PK lab systems with QB Control
Maintain DeltaV for any connected production systems
Bridge via OPC UA if needed
ROI: recover investment in <12 months through eliminated license/support costs
Scenario C: Expanding Parallel Capacity
Recommendation: QB Control for new vessels
Keep existing DeltaV for current bioreactors
Add new parallel capacity with QB Control + QB Modules
No impact on validated DeltaV systems
OPC UA bridge for unified data if needed
Scenario D: CDMO Scaling Up Client Projects
Recommendation: QB Control for client-facing process development
CDMOs need rapid setup/teardown for different client processes
Lower cost per client project = higher margins
DeltaV retained for production-scale manufacturing
Scenario E: Academic/Research Institution
Recommendation: QB Control (full replacement)
DeltaV is prohibitively expensive for teaching/research
Multi-student access via browser (no per-seat licensing)
Modular hardware enables curriculum flexibility

When NOT to Position Against DeltaV
Do NOT position QB Control against DeltaV when the client needs:
Production-scale manufacturing (>200 L bioreactors)
Model Predictive Control or advanced process optimization
PAT/spectral integration for continuous manufacturing
Enterprise multi-site DCS deployment
Safety Instrumented Systems (SIL-rated)
Formal ISA-88 certification requirements
Integration with existing plant-wide MES/ERP
In these cases, position QB Control as complementary to DeltaV — handling lab/pilot while DeltaV handles production.
