Introduction
UMESENET-2201 1
Chapter 1.Introduction
The ESENET is an Ethernet gateway specifically designed to interface Woodward’s
Easygen series genset controls with Modbus/TCP networks and Toolkit. It interfaces via
CAN bus with the Woodward controls.
The ESENET takes advantage of the multi-master capability and fast transmission speed
of CAN to offer short Modbus/TCP poll cycles as well as concurrent access.
A single ESENET added to the CAN network will make all Visualisation Data of connected
Woodward CANopen controls available without adding additional load to the CAN bus
communication. In addition concurrent and fast read and write access to Parameter IDs
is possible utilising parallel CANopen SDO transfers.
In addition to Modbus/TCP access the ESENET provides a Toolkit interface. Using this
facility you can run local and remote Toolkit sessions from your PC via Ethernet and
TCP/IP through the ESENET gateway to Woodward controls connected on ESENET's CAN
interface.
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

Description
UMESENET-2201 7
Principles of operation
The ESENET acts as a CANopen consumer and monitors the CAN bus for transmission
of well-known communciation objects. Once these communication objects identify
one of the supported Woodward controls, the ESENET starts to buffer all multiplexed
visualisation data of such device into its internal data tables.
The ESENET also acts as a Modbus server on the Ethernet interface. It accepts connections
and Modbus queries from Modbus master devices. The Modbus registers are then served
from the ESENET's internal data tables. Because of the data table buffering, the Modbus
can be polled independant of CANopen TPDO transfer cycles. The ESENET allows a
maximum of 8 connections via Modbus/TCP.
