GCP-MG Modbus gateway with Ethernet for Woodward GCP-30 genset controls and LS 4 controls

GCP-31/GCP-32 to Modbus Gateway with CAN and RS-485
Designed for GCP-31/GCP-32 Designed for LS 4 Works with Ethernet Works with Modbus Works with Controller Area Network

GCP-MG is a next-generation Modbus/CAN gateway specifically designed to interface Woodward's GCP-30 series genset controls (GCP-31, GCP-32), 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.

Common applications include:

  • PLC connection
  • Operator panel interfacing
  • HMIs
  • SCADA integration
  • Power station automation
  • Gen set control
  • Remote control & monitoring
