2 Introduction

2.1 Product Design

The Modbus TCP Module allows the soft starter to connect to an Ethernet network and be controlled or monitored using an Ether-

net 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

The Modbus TCP Module is compatible with the following Danfoss soft starters:

MCD 200: 24 V AC/V DC and 110/240 V AC control voltage.

MCD 500: All models.

NOTICE

The Modbus TCP Module is not suitable for use with MCD 200 soft starters using 380/440 V AC control voltage.

2.3 Product Versions

The Modbus TCP Module is available in 2 different versions. The part number is printed on the label on the side of the module.

175G9904 MCD Modbus TCP Module

Monitor and control the soft starter over a Modbus TCP connection.

175G9914 MCD Modbus TCP Module

Monitor and control the soft starter over a Modbus TCP connection.

Monitor and control the soft starter over a TCP connection using VLT® Motion Control Tool MCT 10, refer to the VLT® Motion

Control Tool MCT 10 Operating Guide.

The register addresses for status reporting differ for 175G9904 and 175G9914.

This installation guide is suitable for use with 175G9914. For the manual for 175G9904, contact the local supplier.
