1 Safety

1.1 Disclaimer

The examples and diagrams in this manual are included solely for illustrative purposes. The information contained in this manual is

subject to change at any time and without prior notice. Responsibility or liability is never accepted for direct, indirect, or consequen-

tial damage resulting from the use or application of this equipment.

1.2 Warnings

WARNING

SHOCK HAZARD

Attaching or removing accessories while the soft starter is connected to mains voltage may cause personal injury.

Before attaching or removing accessories, isolate the soft starter from mains voltage.

WARNING

RISK OF PERSONAL INJURY AND EQUIPMENT DAMAGE

Inserting foreign objects or touching the inside of the soft starter while the expansion port cover is open may endanger person-

nel and can damage the soft starter.

Do not insert foreign objects in the soft starter with the port cover open.

Do not touch the inside of the soft starter with the port cover open.

Safety

Modbus TCP Card

Installation Guide

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.

3 Installation

3.1 Installing the Expansion Card

1 2

e77ha739.10

Procedure

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.

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

3.2 Network 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.

4 Device Configuration

4.1 Before Configuring the Device

NOTICE

The error LED flashes whenever the device is receiving power but is not connected to a network. The error LED will flash occa-

sionally during the configuration process.

NOTICE

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.

4.4 Enabling Network Control

NOTICE

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.

Device Configuration

Modbus TCP Card

Installation Guide

Procedure

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

4.5 On-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.

e77ha807.10

Once connected, the web server reports basic information about the card and the soft starter.
