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.

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 TXPDO transfer cycles. The ESENET allows a maximum of 8 connections via Modbus/TCP.

Ethernet & IP configuration

Before configuring the ESENET, obtain a unique static IP address, subnet mask, and default gateway address from your network administrator.

The factory default IP address of the ESENET is 169.254.0.10 which is in the Automatic Private IP Addressing (APIPA) address range.

There are several methods of configuring the unit’s IP address:

  1. Removing your PC from your corporate network and using a cross-over network cable (see [ConfigCrossOver]).

  2. Via the diagnostic port and a terminal program like HyperTerminal (see [ConfigTerminal]).

  3. Leaving your PC connected to your corporate network and temporarily changing the IP settings on your PC to match the subnet of the ESENET (see [ConfigChangeIP]).

Note In order to connect to the ESENET via TCP/IP, your PC must be on same IP subnet as the gateway. In most situations this means that the first three numbers of the IP address have to be identical.

IP setup using a web browser and a cross-over network cable

This method applies only to operating systems like Windows, which support APIPA (Automatic Private IP Addressing). It also requires your PC to be configured for DHCP. If your computer is configured with a static IP address, follow the procedure in [ConfigChangeIP].

  1. Disconnect your PC from your corporate network. If your computer is configured for DHCP it should now automatically fall back to use a default IP address from the APIPA range 169.254.x.x (Windows PCs only).

  2. Connect an Ethernet crossover cable from the ESENET to the computer.

  3. Start Internet Explorer.

  4. In the address box, type 169.254.0.10 and then press Enter.

Running Toolkit via the ESENET gateway

esenet_toolkit.png

Since firmware version 2.0, the ESENET offers a TCP/CANopen-SDO bridge which is linked to a virtual CAN port on the Toolkit PC.

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. The ESENET Toolkit interface can be used in parallel with Modbus/TCP connections.

Prerequisites
  • ESENET gateway with firmware 2.0 or above (existing ESENET devices can be upgraded)

  • proconX CAN Library for Toolkit (available from proconX web site)

  • PC with installed Woodward Toolkit

How it works

For Toolkit to recognise the ESENET gateway as a CAN interface, a virtual CAN port needs to be installed on the Toolkit PC. proconX provides a CAN Library for Toolkit installer which replaces Tookit’s standard Kvaser USB CAN driver with a custom CAN library. This replacement library will emulate a Kvaser USB CAN port using TCP/IP and ESENET's TCP/CANopen-SDO bridge.

Installation

  1. To install, run the self-extracting Installer executable and click Next to continue:

    canlib_install1.png
  2. Click Next to confirm the installation:

    canlib_install2.png
  3. The installation is completed, click Finish to exit the installer:

    canlib_install3.png

You can revert back to Toolkit’s original Kvaser CAN library by simply uninstalling the proconX CAN Library for Toolkit.

Running Toolkit

Launch Toolkit in the usual manner and click on the Connect button to open the Select a network drop-down box. In the Network selection list, choose USB Kvaser Simulated 1 as CAN interface and confirm with Connect.

toolkit_connect.png
Figure 12. Toolkit network selection
Important The USB Kvaser Simulated 1 selection will not show if the proconX CAN Library for Toolkit is not installed!

A dialog box will open and ask for the IP address of the connected ESENET gateway. Enter the correct IP address for the ESENET gateway and click OK.

toolkit_ip_address.png
Figure 13. Entering the ESENET gateway’s IP address in Toolkit

On successful connection, the status in Toolkit’s status line will change from Establishing Connection on USB Kvaser Simulated 1 to Connected on USB Kvaser Simulated 1 as shown below:

toolkit_status.png
Figure 14. Successful CAN over TCP/IP connection

In case of a connection error or a communication error, the Toolkit status will revert back to either Establishing Connection or Reconnecting. In this case terminate the session and establish a new session by clicking Disconnect and Connect again.

toolkit_reconnecting.png
Figure 15. Example of Toolkit indicating a communication error

TCP Ports

The TCP/CANopen-SDO bridge uses the same TCP port as Modbus/TCP which is port 502. Using the same port as Modbus/TCP simplifies router configuration for VPN applications.

Configuration of connected Woodward controls

The ESENET has been designed to keep the configuration effort required to connect the gateway with Woodward CANopen devices to a minimum. In most situations no additional configuration is necessary to get the ESENET communicating with an Easygen-3000 series control. For a LS-5 control the Node-ID has to be changed from the default value of 33 to be in the range of 1-16. Other Woodward controls like the DTSC-200 may require some configuration changes for settings like CAN baudrate and the TXPDO COB-IDs.

The following list of Woodward CAN device parameters affect the operation of the ESENET gateway and their setting should be checked during installation and commissioning:

  • CAN baudrate

  • CANopen Node-ID

  • COB-ID of Transmit PDOs (TXPDO)

  • Data Protocol of the Transmit PDOs (TXPDO)

CAN baudrate

For all CAN devices the CAN baudrate must be set to 250 kBit/s.

CANopen Node-ID and TXPDO COB-ID

To minimise the configuration effort, there is a fixed relationship between the CANopen Node-ID, the Modbus Slave ID and the TXPDO COB-ID which is documented in the table below. The relationship follows the rules of the CANopen Predefined Connection Set PDO assignments. Easygen-3000 and LS-5 controls use the COB-ID range from 385 to 400 and the DTSC-200 devices from 1153 to 1168.

Specific information for Easygen-3000 series controls

The most convenient way to configure the Easygen is using Woodward’s Toolkit software. Below are Toolkit screenshots of the relevant menus.

Configure interfaces

CAN interface

From Woodward’s Toolkit software select the Configure CAN interface 1 page as shown below:

Configure CAN interface 1
Figure 17. "Configure CAN interface 1" menu in Woodward Toolkit
  • Parameter 3156 Baudrate must be set to 250 kBd.

  • Parameter 8950 Node-ID should match the device ID. It must be in the range of 1 to 16 and a unique number in the network. This value also determines the Modbus Slave ID under which the Easygen data can be retrieved.

Transmit PDOs

In order for the ESENET gateway to receive cyclic data updates from the Easygen, one of the five available Transmit PDOs (TXPDO) must be configured. Typically Tranmsit PDO 1 is already pre-configured for that purpose, but any of the five TXPDOs could be used for that purpose.

If for example Transmit PDO 1 is used, then:

  • parameter 9600 COB-ID must be set to 384 + Node-ID,

  • parameter 8962 Selected Data Protocol to 5003 and

  • parameter 9602 Tramsission type to 255.

In the following example for an Easygen with device ID of 1 and Node-ID of 1, the Transmit PDO 1 is used to send data updates every 20 ms:

Transmit PDOs
Figure 18. "Transmit PDOs" menu in Woodward Toolkit
Important All COB-IDs used in the CAN network must be unique. Please make sure that a COB-ID is only configured once. If TXPDO or RXPDO COB-ID entries are referring to an already used COB-ID, either disable that PDO or change the COB-ID.

Specific information for LS-5 controls

The LS-5 CANopen parameters are configured using Woodward’s Toolkit software. Below are Toolkit screenshots of the relevant menus.

  • Parameter 3156 Baudrate must be set to 250 kBd.

  • Parameter 8950 Node-ID must be changed to be in the range of 1 to 16 and a unique number in the network. This value also determines the Modbus Slave ID under which the LS-5 data can be retrieved. One could for example use Node-IDs 1 to 8 for Easygens and Node-IDs 8 to 16 for LS-5s.

Transmit PDOs

In order for the ESENET gateway to receive cyclic data updates from the LS-5, one of the five available Transmit PDOs (TXPDO) must be configured. Typically Tranmsit PDO 1 is already pre-configured for that purpose, but any of the five TXPDOs could be used for that purpose.

If for example Transmit PDO 1 is used, then:

  • parameter 9600 COB-ID must be set to 384 + Node-ID,

  • parameter 8962 Selected Data Protocol to 5301 and

  • parameter 9602 Tramsission type to 255.

In the following example for an LS-5 with device ID of 33 but Node-ID of 8, the Transmit PDO 1 is used to send data updates every 20 ms:

  • Parameter Device number determines the Modbus Slave ID under which the DTSC-200 data can be retrieved. It must be set to a unique number in the network.

  • Parameter Protocol must be set to CANopen and

  • parameter Baudrate to 250 kBd.

Transmit PDOs

In order for the ESENET gateway to receive cyclic data updates from the Easygen, one of the four available Transmit PDOs (TXPDO) must be configured. Typically Tranmsit PDO 4 is already pre-configured for that purpose, but any of the four TXPDOs could be used for that purpose. Other TXPDOs which transmit on COB-IDs reserved for the Easygen (for example 385 and 386) must be disabled or changed to a different COPB-ID range.

If for example Transmit PDO 4 is used, then the following changes are required:

  • TPDO 1 (COB-ID 385) disabled or changed to a different range,

  • TPDO 2 (COB-ID 386) disabled or changed to a different range,

  • TPDO 3 can stay configured if set to to COB-ID 1152 + Node-ID,

  • TPDO 4 parameter COB-ID set to 1152 + Node-ID,

  • TPDO 4 parameter Transmission type set to 255,

  • TPDO 4 parameter 1. Mapped Object set to 03190 in order to select Data Protocol 4700 and the other mapped objects to 00000.

In the following example for a DTSC-200 with device ID of 1, the Transmit PDO 4 is used to send data updates every 20 ms. TXPDO 1 and 2 are disabled because the use COB-IDs reserved for the Easygen.

Modbus data reference

This chapter describes how process data and configuration data of the Woodward controls are organized in logical blocks and accessed via Modbus.

The ESENET supports two principal Modbus data tables one for visualisation and one for configuration & remote control. These data tables are organised in a similar manner to the serial Modbus adress ranges of the Woodward controls. This allows an easy transition from serial Modbus to Modbus/TCP.

The Visualisation Data Table is located at start address 50001 and the Configuration & Control data table is located at start address 1 up to address 49999.

Modbus Slave IDs

The Modbus Slave ID (also known as Unit Identifier or Slave Address) is used to address individual Woodward controls. There is a fixed relationship between the CANopen Node-ID and the Modbus Slave ID which is documented in the table below.

Visualisation Data Table

The Visualisation Data Table provides a very fast and efficient means to read important process data. Because the visualisation data is buffered in the ESENET gateway, the data is replied instantly without blocking the PLC’s Modbus/TCP master communication channel.

The Visualisation Data Table is a dedicated buffer area in the ESENET gateway which is filled in the background by the Woodward control through cyclically transmitted PDOs. Therefore the structure and layout of the Visualisation Data Table depends on the Woodward control used and the configured Data Protocol. The ESENET does not perform any modification to the representation of the data values.

UMESENET__2.png
Figure 26. Message sequence chart for visualiation data

The Visualisation Data Table is located in the so called Input register block, which sometimes is also identified with offset 3:00000. The block is accessed using Modbus function code 04 Read input registers.

Registers in this data table can only be accessed if the CAN communication between ESENET and the Woodward control has been established. If this is not the case, Modbus exception code 0B Gateway target device failed to respond is returned, indicating the Woodward control is not present on the CAN bus.

Please consult the appropriate Woodward manual for exact layout, encoding and representation of the data in the Visualisation Data Table. Some examples for the most commonly used Woodward controls are shown in the following tables:
