EasyAccess 2.0 is a service developed by Weintek that provides secure remote access to operator panels (HMI) and connected devices (PLCs, sensors, industrial controllers) via the Internet, without the need for a dedicated static IP address.

1️⃣ Primary Purpose

• Remote control of Weintek operator panels and connected equipment from anywhere in the world 🌍
• Data transmission over a secure channel (128-bit SSL encryption)
• Support for mobile devices (iOS, Android), PCs, and web browsers
• Operation with both individual HMIs and entire local equipment networks

2️⃣ Main Functions

• 📟 Remote display of the HMI interface
• 🔄 Uploading and updating projects to the HMI
• 📂 File transfer via FTP (if supported by the panel)
• 📊 Viewing event logs and alarm history
• 🔧 Remote diagnostics and equipment configuration
• 🔔 Push notifications to smartphones when events occur

3️⃣ Connectivity and Networking Capabilities

• 🌐 Operation without a static IP address (using the cloud service account.ihmi.net)
• 🖧 VPN tunnel connection with automatic assignment of a unique IP address to each device
• 🔌 Support for over 300 drivers for PLCs and industrial devices
• 📡 Ability to operate via Ethernet, Wi-Fi, or mobile Internet

CODESYS Option transforms Weintek operator panels into powerful HMI+PLC combined devices, enabling not only visualization but also direct programming and control of equipment in compliance with the IEC 61131-3 international standard.

1️⃣ Purpose and Key Concept:

• 🖥️ Combining HMI and PLC in a single device.
• 📜 Control logic programming without the need for an additional hardware PLC.
• 🌐 Performing calculations, signal processing, and process control directly on the panel.

2️⃣ CODESYS Platform:

• 🛠️ Fully compatible with CODESYS V3.5 SP15 Patch 5.
• 📌 Supports IEC 61131-3 programming languages:
  • LD (Ladder Diagram — relay logic)
  • FBD (Function Block Diagram — function blocks)
  • ST (Structured Text)
  • IL (Instruction List)
  • SFC (Sequential Function Chart)
• 📡 Supports Modbus TCP, EtherCAT Master, EtherNet/IP Scanner, CAN for integration with other systems.

3️⃣ Integration with HMI:

• 🔄 Shared access to variables between CODESYS PLC and the HMI project in EasyBuilder Pro.
• 📊 Using PLC variables for visualization, trends, data logging, and alarms.
• 📥 Working with recipes, schedulers, and mathematical data processing.

4️⃣ Network Interaction:

• 🌍 Supports Ethernet and serial interfaces for field device connections.
• 📶 Remote programming and diagnostics via EasyAccess 2.0 or VPN.
• 🖧 Connectivity to SCADA, MES, and cloud services.

5️⃣ Advantages:

• 💰 Saves space and costs — no separate PLC required.
• ⚡ Fast integration into automation systems.
• 🛡️ Flexible logic updates without stopping the HMI project.
• 🔌 Wide device compatibility through Weintek drivers and CODESYS libraries.
