Important user information
This manual explains how to install, operate and configure a GCP-MG. This device may
only be used for the applications described in this document.
These instructions are intended for use by trained specialists in electrical installation
and control and automation engineering, who are familiar with the applicable national
standards and safety procedures.
Safety Precautions
ELECTRICAL HAZARD
• This equipment must be installed and serviced only by qualified personnel. Such
work should be performed only after reading this entire set of instructions.
• Before performing visual inspections, tests, or maintenance on this equipment,
disconnect all sources of electric power. Assume that all circuits are live until they
have been completely de-energized, tested, and tagged. Pay particular attention
to the design of the power system. Consider all sources of power, including the
possibility of backfeeding.
• Apply appropriate personal protective equipment and follow safe electrical
practices.
• Turn off all power supplying the equipment in which the GCP-MG is to be installed
before installing, wiring or removing the GCP-MG.
• Always use a properly rated voltage sensing device to confirm that power is off.
• The successful operation of this equipment depends upon proper handling,
installation, and operation. Neglecting fundamental installation requirements
may lead to personal injury as well as damage to electrical equipment or other
property.
Failure to follow these instructions could result in death or serious injury!

Introduction

Chapter 1.Introduction
The GCP-MG is a next-generation Modbus/CAN gateway specifically designed to interface
Woodward’s GCP-30 Series Genset Controls and LS 4 Circuit Breaker Controls with
Modbus networks.
The GCP-MG gateway has been developed in cooperation with Woodward to ensure the
highest possible degree of interoperability with Woodward equipment.
The gateway features CAN, serial RS-232 and RS-485 ports as well as an Ethernet port and
can be mounted on a DIN rail. On the CAN side it implements the Woodward CAL protocol
to connect to the GCP controls. On the serial ports and on Ethernet it implements a
Modbus server (Modbus RTU and Modbus/TCP) and accepts connections from Modbus
master devices like PLCs and SCADA systems.
Usage and configuration of the gateway is simple and conveniently performed using a
web browser which connects to the embedded web server.
Possible areas of application are:
• PLC connection
• Operator panel interfacing
• HMIs
• SCADA integration
• Power station automation
2UMGCPMG-2201
• Gen set control
• Remote control & monitoring
• Data logging
Features
The GCP-MG gateway provides the following key features:
• Modbus/TCP protocol (Ethernet)
• Modbus RTU protocol (either RS-232 or RS-485, software configurable)
• Interfaces with up to 16 GCP-30 controls and up to 8 LS 4 controls
• Full support of Option SB03 (Cat CCM) and Option SC06 (MTU MDEC)
• Modbus register layout compatible with GW 4
• Dedicated Modbus slave ID for each GCP-30 and LS 4 control
• Large internal buffer for data
• Complete data set of one GCP-30 unit can be read with a single Modbus transaction
• Integer/Exponent value pairs for voltages, power and currents are additionally
represented as 32-bit floating point registers
• Transparent handling of data guarantees compatibility with future Woodward
firmware updates
• Serial baud rate up to 115200 bps
• Support of Modbus function codes 03, 04, 06 and 16
• Concurrently one Modbus serial line and up to two Modbus/TCP connections
• Low configuration overhead, just an IP address
• Embedded web server for easy configuration and commissioning using a web browser
• Firmware upgradeable via Ethernet
• Status LEDs for power, Ethernet link, device status and communication status
• 24 V DC (10-30 V) power supply
• DIN rail mountable
Introduction

Quick start checklist
• Read this set of instructions properly and in its entirety.
• Mount the unit.
• Connect the power. Do not connect yet CAN bus or serial ports.
• Configure the Ethernet communications settings with a web browser (using an
Ethernet crossover cable) or with a terminal program like HyperTerminal (using a null
modem cable)
• Configure the CAN bus settings.
• Configure the serial line communication settings.
• Configure the operational aspects of the device.
• Wire CAN bus.
• Wire serial line interfaces.
