What Is Delta DIAView SCADA?

Delta DIAView is a SCADA (Supervisory Control and Data Acquisition) software system developed by Delta Electronics — one of the world’s leading industrial automation manufacturers. It provides a complete platform for real-time monitoring, data acquisition, process visualization, alarm management, and production reporting for industrial automation applications.

DIAView is part of Delta’s broader DIA (Delta Industrial Automation) software ecosystem, designed to work natively with Delta’s own automation hardware — DVP and AH series PLCs, delta VFDs (AC motor drives), power meters, temperature controllers, industrial robots, and HMI panels — while also supporting third-party equipment through standard protocols.

Version 4.3.1 is the current production release used in most active deployments. The software supports three distinct deployment architectures to match different scale and access requirements.

Delta DIAView is widely used across Southeast Asia, South Asia, and East Asia where Delta’s automation products dominate the market, and is gaining adoption in other regions as Delta expands its global industrial automation footprint.

Who Uses Delta DIAView?

Systems integrators building factory automation solutions on Delta hardware
Manufacturing plants monitoring production lines, machines, and process variables
Water treatment and HVAC facilities requiring centralized process monitoring
Energy management teams integrating Delta power meters with supervisory visualization
Building management system (BMS) integrators connecting HVAC, lighting, and access control
Food, textile, and packaging manufacturers using Delta automation equipment
OEM machine builders embedding DIAView in their machine control consoles

System Architecture Options

DIAView supports three deployment architectures, each suited to different facility sizes and access requirements:

Stand-alone Mode

The simplest configuration — DIAView runs on a single PC that connects directly to field devices (PLCs, drives, meters) and serves as both the data acquisition server and the operator workstation.

Best for: Small facilities, single machine monitoring, compact production lines, or deployments where one operator station is sufficient.

Configuration: One PC running DIAView software, connected via Ethernet or serial to field devices.

Client/Server (C/S) Mode

A dedicated DIAView Server PC handles all communication with field devices, data storage, and processing. Multiple client workstations connect to the server over TCP/IP to display live data and send operator commands.

DIAView Server supports up to 10 simultaneous client connections
Clients can be located anywhere on the corporate LAN
Server runs continuously; clients connect as needed
Operators on different workstations see the same live data synchronized through the server

Best for: Medium to large facilities with multiple control rooms or operator stations, multi-shift operations, or where different departments need access to process data.

Web Browser/Server (B/S) Mode

Extends the C/S architecture with a web server component that serves the operator interface to any standard web browser — enabling monitoring from laptops, tablets, and smartphones without installing the DIAView client software.

Best for: Remote monitoring, management dashboards for supervisors and plant managers, mobile access for maintenance staff, and multi-site enterprise monitoring.

Core Features

Screen hierarchy:

Multiple screens (pages) per project with navigation buttons
Pop-up windows for detailed views or operator input forms
Full-screen and windowed display modes
Multi-monitor support for separate live view and alarm/historical displays

IO Communication — PLC and Device Connectivity

DIAView communicates with field devices through a channel and device configuration model. A channel defines the communication medium and protocol; devices are the physical equipment on that channel.

Communication interfaces supported:

Serial port (RS-232, RS-485)
Ethernet (TCP/IP)
USB (for direct PC-to-PLC connections)

Communication protocols and drivers (20+ protocols):

Delta native protocols:

Delta DVP series PLCs (DVP-12SE, DVP-20SX, DVP-28SS, DVP-32ES, etc.) — via Modbus RTU (serial), Modbus ASCII (serial), Modbus TCP/IP (Ethernet), and Delta proprietary protocols
Delta AH series PLCs (AH500, AH2000) — via Ethernet and serial
Delta HMI (DOP series) — for cascaded HMI-SCADA configurations
Delta power meters (DPM series) — direct integration

Industry standard protocols:

Modbus TCP/IP — connect to any Modbus-compatible device (PLCs, drives, meters from any manufacturer)
Modbus RTU (serial) — legacy serial device integration
Modbus ASCII (serial)
OPC DA — connect to any OPC server, enabling integration with third-party SCADA/PLC systems

Additional drivers:

Various PLC brands via third-party communication drivers
Simulator driver for development and testing without physical hardware

Variable configuration: Variables (tags) map to specific memory addresses in the connected devices. DIAView’s variable dictionary manages all project variables centrally — define name, data type, device address, scaling factors, and engineering units. All screen objects, alarms, historical logs, and reports reference variables by name.

Alarm Management

DIAView’s alarm system monitors process variables against configured limits and notifies operators of abnormal conditions:

Alarm configuration:

Frequently Asked Questions

Is Delta DIAView compatible with non-Delta PLCs? Yes. DIAView includes Modbus TCP/IP, Modbus RTU, and OPC DA drivers that enable communication with PLCs and devices from Siemens, Allen-Bradley, Mitsubishi, Omron, and any other manufacturer supporting these standard protocols. However, the deepest native integration (direct symbolic addressing, automatic variable import) is available for Delta’s own PLCs.

How many I/O tags (variables) does DIAView support? The tag count depends on the license edition. Contact Delta Electronics or your local distributor for current license specifications — editions vary by concurrent I/O count.

Can DIAView connect to OPC servers? Yes. DIAView includes an OPC DA client driver, allowing it to connect to any OPC DA server. This enables integration with Siemens WinCC, Schneider OPC Factory Server, Kepware KEPServerEX, and other OPC-based data sources.

Does DIAView support redundant server configurations? Standard DIAView does not include built-in server redundancy. For mission-critical applications requiring high availability, consult Delta’s enterprise support for available options or consider architectural redundancy at the hardware level.

What is the maximum number of client connections in C/S mode? The base DIAView Server license supports up to 10 simultaneous client connections. For larger deployments requiring more concurrent users, contact Delta for expanded licensing options.

Is there a free version or trial? DIAView includes a built-in simulator mode that allows development and testing without a hardware dongle. This enables learning the software and building projects without purchasing a license. The simulator does not connect to real field devices — it uses simulated variable values for testing screen animations and logic.

Summary

Delta DIAView SCADA 4.3 is the natural and most capable SCADA choice for automation systems built on Delta Electronics hardware. Its native integration with DVP and AH series PLCs, Delta VFDs, and Delta power meters — combined with a competitive price point, straightforward configuration workflow, and support for all standard protocols (Modbus, OPC) for third-party devices — makes it a practical and cost-effective solution for small to medium industrial automation applications.

For large enterprise-scale platforms or systems with highly mixed multi-vendor hardware, more extensive platforms like Ignition or AVEVA may offer advantages in scalability and integration depth.
