Ready to Accelerate Your Controls Commissioning Workflow?

See how Gunatit Solutions's ControlsTwin tool can reduce commissioning time, eliminate field errors, and modernize your testing process.

Built by Engineers,
for Engineers

Gunatit Solutions was established to develop software tools that improve the reliability, efficiency, and predictability of industrial automation and manufacturing systems. Beyond our current platforms such as ControlsTwin and FloorView, our long term goal is to expand into a broader ecosystem of engineering solutions, including future AI-assisted technologies that support smarter commissioning, better decision-making, and more optimized factory operations.

Our Mission

To empower automation engineers with software tools that improve control system validation, enhance production insight, and make commissioning faster, safer, and more reliable.

Our Vision

To make digital validation and intelligent manufacturing insight a standard part of every industrial automation project.

Principles That Drive Every Commit

Precision Engineering

Every feature is built to exacting standards. We understand that a single signal error in industrial automation can cascade into costly failures.

Innovation First Culture

We constantly push the boundary between simulation fidelity and real-world behavior, building tools that evolve alongside the automation industry.

Engineer Centric Design

Gunatit Solutions products are designed with direct input from automation engineers. UI/UX, workflows, and terminology match what engineers actually use on the floor.

Reliability by Design

All tools are validated against real environments, ensuring production ready reliability that engineers can depend on.

What ControlsTwin Can Do

01 — SIL Testing
📋
Software-in-the-Loop Testing
CORE

Run PLC logic inside a virtual environment without physical hardware. Validate inputs, outputs, mode transitions, and machine states comprehensively.

No Hardware Full Logic All States
02 — I/O Simulation
Virtual I/O Simulation
INTEGRATION

Simulate sensors, actuators, and machine signals to reproduce real operating conditions — proximity sensors, limit switches, cylinders, motors, drives, and operator commands.

Sensors Actuators
03 — Sequences
Sequence Verification Engine
PERFORMANCE

Test machine sequences step-by-step. Detect incorrect transitions, missing conditions, and timing issues before deployment to real equipment.

Step-by-Step Timing
04 — Alarms & Faults
Alarm & Fault Simulation
SAFETY

Trigger abnormal scenarios safely and validate recovery behaviour — sensor failures, communication loss, E-stop conditions, and process interruptions all handled before go live.

E-Stop Fault Recovery Safe Testing
05 — Modes
Mode Management Testing
CONTROL

Validate Auto, Manual, Setup, and Maintenance modes. Confirm correct transitions between all operating states without risk to real machinery or production operations.

Auto Mode Manual Mode Transitions
06 — Communications
Cross Communication Signal Validation
DATA

Verify PLC-to-PLC signals, PLC-to-HMI communication, PLC-to-robot handshakes, and PLC-to-MES data exchange before full system integration on-site.

HMI MES Robotics

Shift Verification Earlier in the Lifecycle

01 — Early Detection
🔍
Detect Logic Errors Earlier

Find and fix issues at the software stage, not on the shop floor. Catching errors earlier reduces rework cost by up to 10×.

Bugs Detection Less Rework
02 — Cost Savings
💰
Reduce Commissioning Costs

Less on-site debugging means shorter timelines and lower engineering costs. Arrive prepared — not to troubleshoot.

Lower Cost Faster Delivery
03 — Reliability
Improve Machine Reliability

Thoroughly tested software means fewer surprises when the machine goes live. Build confidence in every sequence before it runs on real hardware.

Fewer Faults Proven Logic
04 — Remote Work
🌐
Enable Remote Commissioning

Validate logic without being on-site with the physical machine. Run full verification cycles from any location, on any schedule.
