EasyBuilder Pro HMI Development Guide

Getting started with EasyBuilder Pro software for designing and deploying HMI applications on Weintek cMT and eMT series touchscreens.

WK-AN-001Weintek EngineeringFebruary 2024

Overview

EasyBuilder Pro is Weintek's free HMI programming software used to develop operator interface screens for the cMT and eMT series touchscreens. With an intuitive drag-and-drop interface, EasyBuilder Pro enables rapid development of sophisticated HMI applications including data logging, alarm management, recipe handling, and multi-language support without programming expertise.

Project Setup and Device Connection

Start a new project by selecting the target HMI model (cMT3090, eMT3070B, etc.) and configuring the PLC connection. EasyBuilder Pro supports over 300 PLC and device drivers including:

  • Allen-Bradley (DF1, EtherNet/IP, Micro800)
  • Siemens (S7-200/300/400/1200/1500)
  • Mitsubishi (FX, Q, iQ-R series)
  • Modbus (RTU, TCP, ASCII)
  • BACnet, OPC UA, and MQTT for IoT applications

Screen Design Best Practices

Design screens with the operator in mind. Use consistent navigation patterns, clear status indicators, and appropriate color coding (green=run, red=fault, yellow=warning). EasyBuilder Pro provides pre-built object libraries with industrial-style gauges, tanks, valves, and motor animations that can be customized.

Simulation and Deployment

Use the built-in offline/online simulator to test screens before deploying to hardware. The simulator emulates the HMI display and PLC communication, allowing complete testing on your PC. Deploy projects via USB, Ethernet, or the cMT Viewer app for remote updates.

Typical Applications

  • Machine operator interfaces
  • Process monitoring dashboards
  • Recipe management systems
  • Alarm and event logging

IoT & Remote Access

cMT Series Remote Monitoring and IoT

Setting up remote monitoring, cloud connectivity, and mobile access for Weintek cMT series HMIs using EasyAccess 2.0 and MQTT integration.

WK-AN-002Weintek EngineeringMay 2024

Overview

The Weintek cMT series architecture separates the HMI runtime from the display, enabling powerful remote access capabilities. The cMT Gateway runs the HMI application and PLC communication, while displays (local or remote) connect as viewers. This architecture enables remote monitoring via mobile devices, cloud data logging, and multi-site management from a central location.

EasyAccess 2.0 Remote Access

EasyAccess 2.0 is Weintek's VPN-based remote access platform that provides secure connectivity to cMT HMIs from anywhere. Features include:

  • Secure VPN tunnel through firewalls (no port forwarding needed)
  • cMT Viewer app for iOS and Android mobile access
  • PC-based cMT Viewer for desktop monitoring
  • Multi-user access with role-based permissions
  • Remote project upload and firmware updates

MQTT and Cloud Integration

cMT HMIs support MQTT protocol for publishing machine data to cloud platforms such as AWS IoT, Azure IoT Hub, and Google Cloud IoT. Configure MQTT topics and payloads in EasyBuilder Pro to stream real-time production data, alarms, and KPIs to cloud dashboards for enterprise-level analytics.

Multi-Site Dashboard

The cMT-iV6 and cMT-G01 models can aggregate data from multiple remote HMIs into a centralized dashboard. Plant managers can monitor all production lines from a single screen, with automatic alerts when any machine enters a fault or low-production state.

Typical Applications

  • Remote machine monitoring
  • Multi-site production dashboards
  • Predictive maintenance data collection
  • OEM remote service and support

Communications

PLC Communication Setup and Troubleshooting

Configuring communication between Weintek HMIs and popular PLC brands including Modbus, Ethernet/IP, and serial protocols with troubleshooting tips.

WK-AN-003Weintek EngineeringAugust 2024

Overview

Reliable communication between the HMI and PLC is the foundation of any operator interface system. Weintek HMIs support over 300 device drivers, but proper configuration is essential for robust operation. This guide covers connection setup for the most common protocols and provides troubleshooting techniques for communication failures.

Modbus RTU/TCP Configuration

Modbus is the most widely used industrial protocol. For Modbus RTU (serial), configure matching baud rate, parity, and stop bits on both HMI and PLC. For Modbus TCP, set the PLC IP address and port (default 502):

  • Modbus RTU: Match baud rate (9600/19200/38400/115200), 8 data bits, parity, 1 stop bit
  • Modbus TCP: Set PLC IP address, port 502, unit ID if using gateway
  • Address format: 0x (coils), 1x (discrete inputs), 3x (input registers), 4x (holding registers)
  • Test with the built-in System Register communication monitor

Ethernet/IP for Allen-Bradley

For Allen-Bradley CompactLogix and ControlLogix PLCs, use the Ethernet/IP driver. The HMI reads tag names directly—no address mapping needed. Configure the PLC IP address and ensure the HMI is on the same subnet. For large tag databases, use the tag import feature to avoid manual entry.

Communication Troubleshooting

When communication fails, check these items in order: physical cable/network connectivity, matching protocol parameters, correct PLC addresses, and firewall/security settings. Use EasyBuilder Pro's "System Parameter Settings → Communication" diagnostic page to view real-time communication status and error counts on the HMI.

Typical Applications

  • New HMI installations
  • PLC retrofit projects
  • Multi-protocol gateway applications
  • Communication troubleshooting
