Overview

EasyBuilder Pro is Weintek's HMI programming software for the cMT and eMT panels, and it's free. You build the screens by dragging objects onto the canvas instead of writing code. Data logging, alarms, recipes, and multi-language switching are all handled in the same tool.

Project Setup and Device Connection

Start a new project by picking the target panel model (cMT3090, eMT3070B, and so on) and setting up the PLC connection. EasyBuilder Pro ships with 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 for the operator. Keep navigation consistent, make status obvious at a glance, and stick to a color convention the plant floor already reads (green=run, red=fault, yellow=warning). The object libraries give you gauges, tanks, valves, and motor animations to start from, and you can restyle any of them.

Simulation and Deployment

Test screens in the built-in simulator before you flash hardware. It emulates both the panel display and the PLC link, so the whole thing runs on your PC. Push the finished project over USB, Ethernet, or the cMT Viewer app when you need to update remotely.

Typical Applications

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

Overview

The cMT series splits the HMI runtime from the display, which is what makes the remote access work. The cMT Gateway runs the application and talks to the PLC; the displays, local or off-site, just connect to it as viewers. That split lets you watch a machine from a phone, log data to the cloud, and manage several sites without standing in front of any of them.

EasyAccess 2.0 Remote Access

EasyAccess 2.0 is Weintek's VPN-based remote access service. It gives you a secure connection to a cMT panel from off-site, without opening ports on the customer's firewall. What you get:

• 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 panels speak MQTT, so they can publish machine data to AWS IoT, Azure IoT Hub, or Google Cloud IoT. You set the topics and payloads in EasyBuilder Pro, then the panel streams production numbers, alarms, and KPIs up to whatever dashboard is reading them.

Multi-Site Dashboard

The cMT-iV6 and cMT-G01 can pull data from several remote panels into one dashboard. A plant manager watches every line from a single screen and gets an alert when any machine faults or drops below its production target.

Typical Applications

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

Overview

If the panel can't talk to the PLC, nothing else on the screen matters. Weintek supports over 300 device drivers, but each one has to be set up right or the link stays flaky. This note walks through the common protocols and what to check when comms drop.

Modbus RTU/TCP Configuration

Modbus is the one you'll hit most often. For Modbus RTU over serial, the baud rate, parity, and stop bits all have to match on the panel and the PLC. For Modbus TCP, set the PLC IP address and port (502 by default):

• 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, use the Ethernet/IP driver. The panel reads tag names directly, so there's no address mapping to do. Set the PLC IP address and keep the panel on the same subnet. If the tag database is large, import it instead of typing every tag by hand.

Communication Troubleshooting

When comms fail, work through it in order: the physical cable or network first, then the protocol parameters, then the PLC addresses, then firewall and security settings. EasyBuilder Pro's "System Parameter Settings → Communication" page shows live status and error counts right on the panel.

Typical Applications

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