Haiwell Cloud SCADA 3.32 — Complete Guide to the Free Industrial Automation Monitoring Platform

What Is Haiwell Cloud SCADA?

Haiwell Cloud SCADA is a free industrial automation monitoring and management platform developed by Xiamen Haiwell Technology Co., Ltd. (厦门海为科技有限公司), a Chinese industrial automation manufacturer founded in 2005. It serves as both the SCADA software for Haiwell’s hardware ecosystem and as the programming and management tool for Haiwell IIoT HMI panels, Cloud Box gateways, and Industrial PCs.

The single most important fact about Haiwell Cloud SCADA: it is completely free. There is no software license fee, no tag count limit in the base product, and no time-limited trial — the full application is available as a free download from Haiwell’s website. This positions it fundamentally differently from enterprise SCADA platforms like Siemens WinCC ($15,000+), Wonderware/AVEVA ($25,000+), or even mid-market options like Ignition ($25,000+).

Current version: 3.43 (latest as of early 2026). Version 3.32 is the version referenced on the docrack.me download page, with 3.43 the current release. The software receives regular updates.

System requirements:

OS: Windows XP SP2 or higher (Windows 10/11 recommended)
.NET Framework 2.0/3.0/3.5 (3.5 recommended)
Display: 800×600 minimum, 1024×768 recommended, 32-bit color
Processor and RAM: Standard Windows PC requirements

Who uses Haiwell Cloud SCADA:

OEM machine builders who deploy Haiwell HMI panels and need matching SCADA software at zero additional cost
Small and medium-sized manufacturing facilities implementing their first SCADA system on a limited budget
System integrators working with Haiwell hardware in Asia, Southeast Asia, Middle East, and increasingly Eastern Europe
Industrial engineers in post-2022 markets where Western automation brands face supply and pricing challenges
Water treatment, food processing, HVAC, packaging, textile, plastics, and general manufacturing applications

The Strategic Context: Why Haiwell SCADA Matters in 2025–2026

Haiwell Cloud SCADA occupies a specific and increasingly important niche in the industrial automation landscape:

The Chinese industrial automation tier: Haiwell is not in the same tier as Siemens, Rockwell, or Schneider Electric — it is a Chinese mid-market automation vendor competing with brands like Delta, Weintek, and Inovance for the global market for affordable industrial automation hardware. Within this tier, Haiwell’s SCADA being completely free gives it a meaningful advantage over competitors that charge per HMI for their configuration software.

Post-2022 market dynamics: Since 2022, supply constraints and pricing changes for Western automation brands have accelerated adoption of Chinese automation hardware — including Haiwell — in markets across Eastern Europe, Central Asia, and the Middle East. For engineers in these markets who find themselves working with Haiwell hardware, understanding Haiwell Cloud SCADA is increasingly practically relevant.

The free software advantage: For OEM machine builders who ship dozens or hundreds of machines per year, SCADA software licensing costs per machine add up significantly. Haiwell’s zero-license-fee model changes the economics of machine-embedded SCADA, making it viable to include SCADA visualization on machines where the cost would previously have been prohibitive.

Core Features

Real-Time Visualization and HMI Design

Haiwell Cloud SCADA provides a graphical configuration environment for creating process visualization screens:

Graphics and display tools:

Drag-and-drop design canvas with configurable resolution
Library of primitive elements: tanks, pipes, pumps, valves, motors, gauges, meters, indicators
Bitmap image support — import custom graphics and background images
Animation: element visibility, color change, position movement, scaling based on tag values
Trend displays: real-time and historical trend curves
Data grid tables for tabular display of multiple variables
Bar charts, pie charts, and custom shapes
Text labels, input fields, and button controls

Multi-screen projects: A single Haiwell Cloud SCADA project can contain multiple screens, with configurable navigation between them — from a main overview screen to individual process area detail screens.

What you can visualize:

Real-time PLC register values displayed as numbers, bar fills, or graphical animations
I/O status (digital inputs/outputs shown as on/off indicators or animated elements)
Temperature, pressure, level, flow readings from connected instruments
Motor speed, inverter frequency, energy consumption
Production counters, batch counts, shift totals
Equipment status (running, stopped, fault, maintenance mode)

Protocol Support and Connectivity

Haiwell Cloud SCADA’s connectivity is its most practically important feature for installations using non-Haiwell equipment:

Native Haiwell hardware connection: Direct, seamless communication with all Haiwell hardware:

Haiwell IIoT HMI panels (all series)
Haiwell Cloud Box (CBOX) gateways
Haiwell IoT PLC
Haiwell Intelligent Gateways (EBOX)
Haiwell TVBOX large-screen controllers

MQTT protocol:

Full MQTT client support: subscribe and publish to MQTT topics
Built-in MQTT server (broker): Haiwell Cloud SCADA can act as its own MQTT broker — devices can connect to the SCADA PC directly without needing a separate MQTT infrastructure
Connect to cloud MQTT services: AWS IoT Core, Azure IoT Hub, EMQX, HiveMQ, Mosquitto
MQTT topic subscription for receiving data from remote field devices
MQTT publish for sending commands or data to remote devices or cloud systems

Haiwell Cloud Data Center: Haiwell provides its own cloud service that eliminates the need for users to set up and maintain their own MQTT server. Haiwell Cloud-enabled hardware connects to Haiwell’s cloud, and Haiwell Cloud SCADA connects to the same cloud — enabling remote monitoring and control without network port forwarding or VPN configuration. This significantly lowers the infrastructure burden for small operations.

Third-party device protocols (built-in drivers):

Modbus RTU — RS-232/RS-485 serial communication with PLCs, inverters, energy meters, instruments
Modbus TCP — Ethernet-based Modbus for modern devices
OPC DA / OPC UA — connect to OPC servers from Siemens, Rockwell, Schneider, and other vendors
Numerous built-in PLC drivers for major brands (Delta, Mitsubishi, Omron, Siemens S7, Schneider, and others — confirm current driver list from Haiwell documentation)
Serial protocols for instruments and meters (multiple standard meter communication protocols)

Database connectivity:

MySQL — store real-time and historical data in a MySQL database
SQL Server — Microsoft SQL Server integration for enterprise environments
Integrated data-link tool that handles the read-write connection to the database
Historical data queryable from within the SCADA application for trend display and reports

ERP/MES integration: Through database or MQTT connections, Haiwell Cloud SCADA can exchange data with ERP (Enterprise Resource Planning) and MES (Manufacturing Execution System) platforms — pushing production counts, alarm events, and process data upward in the enterprise data hierarchy.

Cloud Transparent Transmission

One of Haiwell Cloud SCADA’s most technically distinctive features: cloud-transparent PLC programming and management.

When a Haiwell Cloud-enabled HMI or gateway is connected to Haiwell Cloud, an engineer at a remote location can use Haiwell Cloud SCADA to:

Remotely program the connected PLC — upload and download PLC programs without being physically on-site
Upload and download HMI programs to the connected HMI panel
Perform firmware upgrades on connected devices over the cloud connection
Run diagnostics — monitor PLC program execution, check I/O states, force outputs
Monitor and debug PLC programs in real time — the same as if physically connected to the PLC

This turns Haiwell Cloud SCADA from a pure visualization tool into a complete remote management platform for Haiwell installations. For OEM machine builders with installed bases in multiple locations, this eliminates the need for on-site service visits for software-related issues.

Security mechanism: Haiwell Cloud uses an A/B Key security mechanism — two-key authentication for secure remote access. Device owners can grant or revoke access to specific remote users without exposing the device to the open internet.

JavaScript Scripting

Unlike many entry-level SCADA platforms that use proprietary scripting languages or visual logic blocks, Haiwell Cloud SCADA uses JavaScript as its scripting language:

What you can do with JavaScript scripting:

Perform calculations on tag values (unit conversion, engineering unit scaling, derived values)
Implement conditional logic (if a tag exceeds a threshold, trigger an action)
Control screen navigation based on logic conditions
Generate dynamic text strings based on data values
Implement custom alarm logic beyond the standard alarm configuration
Create data processing pipelines (aggregate values, calculate averages, track min/max)
Interface with external systems through HTTP/REST calls (in appropriate contexts)
Automate repetitive operations (scheduled reports, periodic data export)

Why JavaScript matters: Traditional entry-level SCADA tools use simplified scripting or no scripting at all, making complex automation logic impossible without external systems. JavaScript support means Haiwell Cloud SCADA can implement sophisticated logic that would otherwise require separate software layers. For engineers already familiar with JavaScript from web development or other contexts, the learning curve is minimal compared to proprietary scripting languages.

Alarm Management

Haiwell Cloud SCADA includes a configurable alarm system for industrial event notification:

Alarm configuration:

Define alarm conditions on any tag: high limit, low limit, value equal, value not equal, rate of change
Configurable alarm priorities/categories
Alarm acknowledgment — operators confirm they have seen and understood an alarm
Alarm history logging — all alarms recorded with timestamp, value, and operator acknowledgment
Alarm display: real-time alarm list, historical alarm viewer, alarm statistics

Alarm notification channels:

On-screen display — alarm banner and alarm window within the SCADA application
Computer voice — text-to-speech audio alarm announcement through the PC speakers
WeChat — notification to WeChat accounts (relevant for Chinese deployments and international teams using WeChat)
SMS — text message notification to configured phone numbers
Email — alarm email to configured recipients

Alarm routing: Alarm notifications can be configured to reach specific personnel based on the alarm category or time of day — for example, engineering alarms go to the maintenance team, while production alarms go to the shift supervisor.

Historical Data and Trending

Data logging:

Configure any tag for historical logging at defined intervals (e.g., every second, every minute, every hour)
Data stored in MySQL or SQL Server database
Historical data retained according to database capacity and retention policy

Trend displays:

Real-time trend: last N minutes/hours of data displayed as scrolling chart
Historical trend: query database for data across any time range and display as chart
Multiple pens per chart — display several tags on the same trend for correlation
Zoom, pan, and time range selection

Reports:

Tabular data reports from historical database
Shift reports, daily reports, production summaries
Export to Excel/CSV formats

Remote Access and Secondary Configuration

Browser-based remote access: Once a project is running on a Haiwell Cloud SCADA server, it can be viewed and operated from any networked computer’s web browser — no additional SCADA software installation required on the client machine. The screen displays identically on the remote browser as on the server.

Mobile monitoring:

Haiwell Cloud APP (iOS and Android) provides remote monitoring and control from smartphones and tablets
Real-time data display, alarm notifications, and basic control from mobile
Access via Haiwell Cloud without network configuration

Secondary configuration (what Haiwell calls “re-configuration”):

Variable data from the main SCADA project can be flexibly referenced in secondary configurations
Enables centralized control of off-site equipment where each remote site has its own local configuration but the central SCADA aggregates data from all sites
Particularly useful for distributed installations: water treatment networks, power substations, remote pump stations, agricultural irrigation systems

Haiwell SCADA in the Broader IIoT Ecosystem

Haiwell Cloud SCADA is designed as the software center of a broader hardware and cloud ecosystem:

Haiwell TVBOX — Large Screen Controller: The TVBOX is a dedicated controller for large-screen industrial dashboards and control room displays. Haiwell Cloud SCADA projects can be displayed on large TV/monitor screens through TVBOX, with real-time data, alarms, camera feeds, and multi-screen layouts. TVBOX is controlled via mobile phone rather than a traditional remote. This creates a visualization center for production floors, control rooms, and monitoring stations.

Haiwell Cloud Platform (website): The Haiwell Cloud Platform is a web-based dashboard portal where cloud-connected devices are visible and manageable. Multiple Haiwell deployments across different sites appear on a single cloud dashboard — geographic overview of all connected equipment. Complements the desktop SCADA for multi-site enterprise deployments.

Haiwell Cloud APP: Mobile iOS and Android app for remote device access. Mirrors the SCADA project display on the smartphone screen without requiring a separate mobile-specific configuration — what you design on the desktop SCADA appears the same way in the app.

The verdict on Haiwell vs enterprise SCADA: Haiwell Cloud SCADA is not a replacement for Ignition, WinCC, or Wonderware in large enterprise applications with diverse hardware, complex ISA-95 data models, extensive third-party integrations, and stringent cybersecurity requirements. Its value is different: it delivers functional SCADA capability at zero software cost for installations that are predominantly or exclusively Haiwell hardware. For OEM machine builders and small-to-medium manufacturing sites deploying Haiwell hardware, the free pricing is the decisive advantage — SCADA functionality that would cost $15,000+ from a Western vendor is included at no additional charge.

Typical Application Scenarios

OEM Machine Builder: A manufacturer of industrial packaging machines builds 150 machines per year, each with a Haiwell HMI panel. By using Haiwell Cloud SCADA as the supervisory layer, they can add remote monitoring capability to every machine without SCADA licensing costs — at scale, this saving is significant. The cloud transparent transmission also means remote firmware updates and PLC program changes without on-site visits.

Water Treatment / Pump Stations: A municipal water utility operates 20 remote pump stations across a rural region. Each pump station has a Haiwell gateway connected to Modbus RTU pump controllers and level sensors. Haiwell Cloud SCADA aggregates all 20 sites on a central monitoring screen, with alarm notifications via SMS when pump failures occur.

Frequently Asked Questions

Is Haiwell Cloud SCADA really completely free? Yes. Haiwell explicitly states there is no software license fee. The software is downloadable at no cost and there are no tag count or screen count limitations imposed by licensing. The business model is hardware sales — Haiwell earns revenue on its HMI panels, PLCs, gateways, and cloud services, not on the SCADA software.

Can Haiwell Cloud SCADA connect to non-Haiwell PLCs? Yes, through Modbus RTU/TCP (which most industrial PLCs and instruments support) and OPC DA/OPC UA. For direct driver support of specific non-Haiwell PLCs (Delta, Mitsubishi, Siemens, etc.), consult the current driver list in the Haiwell documentation as driver availability expands with software versions.

Is Haiwell Cloud SCADA suitable for large installations (1000+ tags)? Haiwell Cloud SCADA can handle large tag counts, but it is fundamentally positioned for small to medium applications (tens to hundreds of tags in typical deployments). For large enterprise SCADA deployments with thousands of tags, strict cybersecurity requirements, complex data models, and extensive third-party integrations, enterprise platforms like Ignition are better suited. Haiwell SCADA’s advantage is cost efficiency for smaller-scale applications on Haiwell hardware.

Does Haiwell Cloud require internet connectivity to function? No. The core SCADA functionality (HMI design, runtime, PLC communication via local network or serial) works without internet. Internet is only required for Haiwell Cloud features: remote access through Haiwell Cloud Data Center, cloud alarm notifications (WeChat, SMS), and cloud transparent PLC programming.

Can Haiwell Cloud SCADA run redundantly (hot standby)? This is an advanced feature not prominently featured in Haiwell’s basic SCADA documentation. For safety-critical applications requiring hot standby redundancy, verify this capability with Haiwell or their local distributors before designing the system.

Summary

Haiwell Cloud SCADA 3.32 (current: 3.43) is a fully functional industrial SCADA platform that distinguishes itself from all Western competitors through a single decisive characteristic: it is completely free. For users building systems around Haiwell’s hardware ecosystem — IIoT HMI panels, Cloud Box gateways, IoT PLCs, and industrial PCs — it provides real-time visualization, MQTT/Modbus/OPC UA connectivity, JavaScript scripting, cloud remote monitoring, alarm management with SMS/email/WeChat notification, historical data logging, and cloud-transparent PLC remote programming at zero additional software cost.

It is not positioned to replace enterprise SCADA platforms in large, diverse, multi-vendor installations with complex requirements. But for OEM machine builders deploying Haiwell hardware at scale, and for small-to-medium manufacturing and infrastructure facilities looking for capable SCADA without the licensing overhead of Western platforms, it delivers substantial value at a price point that no competitor matches.
