Modbus TCP Card

Installation Guide	Introduction

2 Introduction

2.1 Product Design

The Modbus TCP Card allows the soft starter to connect to an Ethernet network and be controlled or monitored using an Ethernet communication model.

Familiarity with Ethernet protocols and networks is required to operate the device successfully. For difficulties arising from using this device with 3rd-party products, including PLCs, scanners, and commissioning tools, contact the relevant supplier.

2.2 Compatibility

This communication expansion card is suitable for use with VLT® Soft Starter MCD 600.

This Installation Guide is intended for use with version 2.x of the VLT® Soft Starter MCD 600 Modbus TCP Card. Version 1.x of the Modbus TCP Card does not support custom users, TCP connection, or IoT operation.

2.3 Network Connection

Table 1: Supported Protocols

Protocols

Installation Guide	Installation

3 Installation

3.1 Installing the Expansion Card

<![if ! IE]>

<![endif]>e77ha739.10

Procedure

1.Push a small flat-bladed screwdriver into the slot in the center of the expansion port cover and ease the cover away from the soft starter.

2.Align the card with the expansion port. Gently push the card along the guide rails until it clicks into the soft starter.

3.2Network Connections

3.2.1 Ethernet Ports

The device has 2 Ethernet ports. If only 1 connection is required, either port can be used.

3.2.2 Cables

When connecting to the device, make sure that the cables are of 1 of the following categories:

•Category 5

•Category 5e

•Category 6

•Category 6e

3.2.3 EMC Precautions

To minimize electromagnetic interference, Ethernet cables should be separated from motor and mains cables by 200 mm (7.9 in). If the Ethernet cable must cross motor or mains cables, the crossing should be at an angle of 90°.

3.3 Network Establishment

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

3.4 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.

Installation Guide	Device Configuration

4 Device Configuration

4.1 Before Configuring the Device

N O T I C E

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.

N O T I C E

At power-up, the communication card loads the IP address stored in the soft starter.

4.2 Configuration Methods

Network communication parameters for the communication card can be set via the soft starter or via the on-board web server.

•The card uses a static IP address by default. To enable DHCP addressing, set parameter 12–20 DHCP to enable or change the setting via the on-board web server.

•The IP address can be set via the programmable parameters of the soft starter.

•The web server can configure the IP address and messaging settings for MQTT/OPC UA operation.

4.3 Parameters for Configuring Network Settings

Use parameters 12-8 to 12-21 to configure the network address. The parameters can be set via the Main Menu, via the Setup Tools, or by uploading a configuration file via USB Save & Load.

Parameter	Default

12-8 Gateway Address	192

12-9 Gateway Address 2	168

12-10 Gateway Address 3	0

12-11 Gateway Address 4	100

12-12 IP Address	192

12-13 IP Address 2	168

12-14 IP Address 3	0

12-15 IP Address 4	2

12-16 Subnet Mask	255

12-17 Subnet Mask 2	255

12-18 Subnet Mask 3	255

12-19 Subnet Mask 4	0

12-20 DHCP	Disable

12-21 Location ID	0

4.4 Enabling Network Control

N O T I C E

If the reset input is active, the soft starter does not operate. If a reset switch is not required, use parameter 7-9 to set the reset input to normally open or fit a link across terminals RESET, COM+ on the soft starter.

Modbus TCP Card

Installation Guide	Device Configuration

Procedure

1.Set parameter 1-1 Command Source to Network for the soft starter to accept commands from the Modbus TCP Card.

4.5On-board Web Server

4.5.1 Connect to the Device

To configure settings using the on-board web server, the Modbus TCP Card must be installed in a soft starter, control power must be available, and the card and computer must both be connected to the Ethernet network.

The computer must use a fixed IP address (not DHCP) and the same subnet mask as the card. The default IP address for the card is 192.168.0.2. The default subnet mask is 255.255.255.0.
