4.3 Network Establishment
The controller must establish communications directly with each device before the device can participate in the network.

4.4 Addressing
Each device in a network is addressed using a MAC address and an IP address. The device can be assigned a static IP address during configuration or can be configured to accept a dynamic IP address (via DHCP). The MAC address is fixed within the device and is printed on a label on the front of the device.

5 Device Configuration

5.1 Before Configuring the Device

ℹ️ NOTICE
To avoid IP address conflicts and to ensure successful deployment, connect the device directly to a PC or laptop to configure the IP address, before connecting to the network.

ℹ️ NOTICE
The error LED flashes whenever the device is receiving power but is not connected to a network. The error LED will flash occasionally during the configuration process.

5.2 Configuration Methods
Ethernet attributes can be configured directly in the device using the on-board web server. The module is configured with a static IP address as default. A new address can be assigned during configuration, or the device can be configured to accept a dynamic IP address (via DHCP). The web server can configure the IP address and messaging settings for MQTT or OPC UA operation. If it is not possible to connect to the web server, use the Ethernet Device Configuration software to scan the network and identify the device.

6.2 Assembly Objects

Table 2: Supported Assembly Objects

7 Operation

7.1 Requirements for Successful Operation
The EtherNet/IP module is conformance-tested to ODVA. For successful operation, the scanner must also support all functions and interfaces described in this manual.

7.2 Device Classification
The EtherNet/IP module is an I/O adapter and must be managed by an I/O scanner over Ethernet. The EtherNet/IP module supports both implicit (cyclic) and explicit (acyclic) messaging.

7.3 Enabling Network Control

• MCD 200: For the soft starter to accept the fieldbus commands, a link must be fitted across terminals A1-N2 on the soft starter.
• MCD 500: Input links are required across terminals 17 and 25-18 if the soft starter is being operated in auto-on mode. In hand-on mode, links are not required.

Control via the fieldbus communication network is always enabled in local control mode and can be enabled or disabled in remote control mode (parameter 3-2 Comms in Remote). See the VLT® Soft Starter MCD 500 Operating Guide for parameter details.

7.4 Ensuring Safe and Successful Control
Data written to the device remains in its registers until the data is overwritten or the device is reinitialized. The EtherNet/IP module will not transfer successive duplicate commands to the soft starter.

• If the soft starter is started via fieldbus communications but stopped via the LCP or a remote input, an identical start command cannot be used to restart the soft starter.
• If the soft starter may also be controlled via the LCP or the remote inputs (as well as via fieldbus communications), a control command should be immediately followed by a status query to confirm that the command has been actioned.

9 Network Design

9.1 Star Topology
In a star network, all controllers and devices connect to a central network switch.

Illustration 4: Example of Star Topology shows this arrangement.

9.2 Line Topology
In a line network, the controller connects directly to one port of the first device. The second Ethernet port connects to another device, which in turn connects to another device until all devices are connected.

Illustration 5: Example of Line Topology illustrates this.

ℹ️ NOTICE
The device has an integrated switch to allow data to pass through in line topology. The device must be receiving control power from the soft starter for the switch to operate.

ℹ️ NOTICE
If the connection between 2 devices is interrupted, the controller cannot communicate with devices after the interruption point.

9.3 Ring Topology
In a ring topology network, the controller connects to the first module via a network switch. The second Ethernet port of the module connects to another device, which in turn connects to another device until all devices are connected. The final device connects back to the switch. The device supports beacon-based ring node configuration.

Illustration 6: Example of Ring Topology shows this configuration.

9.4 Combined Topologies
A single network can include both star and line components.
