Introduction to Field Network Parameter Configuration

In a field network, devices communicate data and commands across interconnected systems. Setting parameters correctly is essential for network stability, as each device must be configured to recognize others on the network, align with communication protocols, and operate within specified performance limits. By using MELSOFT Navigator, you can define and manage these settings within a single platform, reducing setup time and ensuring consistency.

Step 1: Preparing MELSOFT Navigator for Field Network Configuration

To begin, open your MELSOFT Navigator project:

Launch MELSOFT Navigator and open the project containing your field network setup.
Verify that all networked devices, such as PLCs and I/O modules, are included in the Project Tree.
Ensure each device is placed accurately within the Configuration Diagram Panel to reflect the field network layout.

Proper project organization is essential for setting parameters efficiently.

Step 2: Accessing Device Parameter Settings in MELSOFT Navigator

Once your network devices are in place, access each device’s settings:

In the Project Tree, select a device within the field network.
Open the Parameter Settings Panel to view configurable parameters, such as device ID, IP address, and communication protocols.
For each device, enable necessary communication options, ensuring it recognizes and interacts with other devices in the network.

Reviewing each device’s individual settings helps ensure compatibility across the network.

Step 3: Configuring Network-Specific Parameters

Network parameters are critical for effective communication across field devices. Key settings include:

Device IDs and Addresses: Assign unique identifiers to each device, preventing data conflicts.
Communication Protocols: Select protocols like CC-Link IE or Ethernet/IP, based on network requirements.
Baud Rate and Transmission Speed: Adjust communication speeds to match the network’s capabilities and minimize latency.

Ensure these parameters align with the network’s hardware and expected data flow.

Step 4: Setting Device-Specific Operational Parameters

After configuring network parameters, fine-tune each device’s specific settings to match its role in the field network:

Define I/O Channel Settings for sensors or actuators, ensuring input/output signals align with project demands.
Set Error Detection and retry options, enhancing data reliability.
Adjust operational settings such as polling frequency or sampling rates, ensuring they suit the application requirements.

Customizing each device’s operational settings ensures they operate efficiently within the field network.

Step 5: Saving and Verifying the Network Configuration

With all parameters configured, save the project and verify settings:

Select Save Project to store all changes.
Run a Simulation Test in MELSOFT Navigator to check device interactions and confirm data accuracy.
Check for communication stability, ensuring all devices are properly connected and synchronized within the field network.

Testing validates that the network operates as intended, and settings align across all devices.
