Introduction to Field Network Configuration

A field network connects various industrial devices, such as PLCs, HMIs, and I/O modules, allowing them to share data and communicate efficiently. In MELSOFT Navigator, creating a network configuration diagram simplifies and visualizes the setup, making it easier to monitor, troubleshoot, and manage devices within the network.

This guide walks through configuring a field network in MELSOFT Navigator, focusing on setting up modules, configuring network parameters, and finalizing the network structure.

Step 1: Setting Up a New Field Network Project

1. Open MELSOFT Navigator and create a new project by selecting “New Project” in the File menu.
2. Choose Field Network as the project type, and name the project appropriately for easy identification.
3. Select a save location and confirm the network type, such as CC-Link IE Field or another supported protocol.
4. After clicking Create, the project will appear in the Project Tree, with the field network configuration ready to be set up.

By establishing a new project specifically for a field network, you can better organize devices and ensure compatibility across networked modules.

Step 2: Adding Controllers and Network Modules

The controllers and network modules serve as the core of the field network, facilitating communication between connected devices.

1. Go to the Module Library within MELSOFT Navigator and select the controller (e.g., an iQ-R or iQ-F series CPU).
2. Drag and place the controller in the Configuration Diagram Panel to begin the network setup.
3. Next, select a network module compatible with your field network type. Common options include CC-Link IE Field Network Module or Ethernet modules for TCP/IP connections.
4. Position the network module next to the controller, ensuring it is properly connected in the Configuration Diagram Panel.

Adding controllers and network modules is essential, as these devices enable the communication infrastructure for the entire field network.

Step 3: Configuring Network Parameters

Network parameters define how devices communicate, ensuring synchronized data exchange across the network.

1. Access Parameter Settings for the network module by selecting it in the Configuration Diagram Panel.
2. Define settings such as station numbers, baud rates, IP addresses, and subnet masks based on the network requirements.
3. Set up data-sharing options, allowing devices to exchange information reliably over the field network.
4. Verify that network addresses and station numbers are unique and align with the system architecture to prevent communication conflicts.

These parameters are critical for efficient data transmission across the field network, improving reliability and response times.

Step 4: Adding and Configuring I/O and Specialty Modules

With the network module set up, add input/output (I/O) and specialty modules to complete the field network configuration.

1. From the Module Library, select I/O modules relevant to your setup, such as digital or analog input modules, and place them within the Configuration Diagram Panel.
2. Configure each I/O module by adjusting channel settings, data types, and update rates under Parameter Settings.
3. If your network requires specialized functionality, add specialty modules (e.g., high-speed counter modules or communication converters) and configure their parameters to meet specific requirements.

These modules allow the field network to process data from sensors, actuators, and other industrial devices, making real-time automation possible.

Step 5: Testing and Verifying the Field Network Configuration

Testing the configuration ensures that all devices communicate effectively, minimizing the risk of issues during real-world implementation.

1. Use the Simulation Tool in MELSOFT Navigator to simulate network communication, ensuring all modules respond as expected.
2. Run a connectivity test to verify that each device can send and receive data.
3. Adjust any parameters as needed based on the test results to optimize network communication and stability.

By simulating the field network, you can identify and resolve potential issues early, creating a robust and dependable setup.
