INTRODUCTION
1.1 Important user information
1.2 General
MCD 3000 – PROFIBUS GATEWAY
This manual describes operation and programming of a
PROFIBUS gateway for MCD3000 series soft starters, gateway
firmware revision 2.11.
Gateway with firmware version 2.11 complies with MCD3000
protocol as described in Danfoss manual AMB00000 Rev. G
and is likely to be incompatible with earlier versions of the soft
starter. Remote programming of parameters is not supported
at the moment. Contact Fieldbus Specialists if you require a
firmware version that supports earlier models.
Observe all the necessary safety precautions when controlling
any MCD 3000 series device over the serial communications
link, including alerting personnel that the machinery may start
without warning.
The MCD 3000 series of solid state soft starters incorporate a
serial communications facility that allows for the remote
control and interrogation of the MCD 3000 from an intelligent
host (master) via a multi-drop RS-485 communications network
using a proprietary protocol, specific to MCD 3000 devices.
The RS-485 link may be used to interface a MCD 3000 device to
a PROFIBUS network using the PROFIBUS to MCD 3000 gateway.
The PROFIBUS Master can then control any connected MCD
3000 device – start it, stop, reset trip conditions and read
operational status, motor conditions or trip status.
The PROFIBUS to MCD 3000 Gateway is a certified PROFIBUS
slave device. A number of gateways and other PROFIBUS
slave devices can be connected to the same network, subject
only to standard PROFIBUS limitations.
The gateway is a master on the RS-485 multi-drop MCD 3000
communications network.
connected to a single Gateway. In this way up to 30 MCD
3000 devices will share one PROFIBUS address on the PROFIBUS
communications network.
This manual describes how the PROFIBUS to MCD 3000
gateway operates, how to connect MCD 3000 series soft
starters to the gateway and how to connect and operate the
gateway on a PROFIBUS network.
Up to 30
MCD 3000 devices may be

A gateway can coexist with a number of other PROFIBUS
nodes, including other gateways. Each gateway constitutes a
single PROFIBUS node, even if it connects to a number of MCD
3000 devices.

These simple rules may be worth remembering:
- Flashing indicates errors on the relevant link,
- Flashing red means that the gateway attempts to
communicate but fails every time,
- Flashing red/green means that the gateway can
communicate, but errors occur.
