PURPOSE

You have just received your brand new eWON500™!

ACT’L produces a complete range of Ethernet/Internet gateways also known as “Programmable Industrial Routers” (PIR). See our web site http://www.ewon.biz to get further information about the eWON™ range.

The goal of the current document is to teach you how to correctly configure the eWON500™ as a Configurable Gateway to address a wide range of various Programmable Logic Controllers (PLC), from the Ethernet side to the serial side through the eWON™ interface.

eWON500™ is just out of the box, you have already powered it ON (12-24VDC) and connected its Ethernet cable.

• Enter http://10.0.0.53 in the address bar from your Internet Explorer (refer to the eBuddy User Guide if you need to change the eWON™ IP address and subnet mask)

• Enter adm (User Name)/adm (Password) then Enter

You are now navigating on your eWON500™!

The eWON500™ is a configurable gateway: it can retrieve data from several protocols and publish them as Modbus

TCP registers or SNMP registers.

Every eWONs™ are shipped with the pre configured IP address 10.0.0.53 and adm/adm as User Name/Password.

ModbusTCP/SERIAL GATEWAY

Principles The eWON500™ is a configurable gateway: it enables a connection between a supervisor or an

industrial software and the eWON500™ through the TCP link (with protocol=ModbusTCP). This gateway then allows to read in the eWON500™ an existing Tag which reads a word on a PLC linked to it by its serial interface (with a serial protocol such as UNITE, NETMPI, DF1, FINS and S5-AS511).

Configurable Gateway configuration with eWON500™

The eWON500™ configurable serial port

Depending on the serial link which is supported by the target PLC, the eWON500™ serial port dip-switches (left bottom side from the eWON500™ when you face its LEDs panel) must be configured for RS-232 or RS-485 mode.

A label describing the switches configuration stands just close from the dip-switch panel.In case of doubt, please refer to the eWON500™ Installation Guide (Configurable serial port chapter) you can download from the eWON web site:(http://www.ewon.biz Support/Documentation/User guides).

The eWON500™ IO servers

The eWON500™ requires a kind of driver to be able to “speak” the protocol from the PLC. At this time, the eWON500™ embeds several drivers (called IO servers), each of them can be configured from a distinct configuration web page from the eWON500™ interface:From the eWON500™ main menu, click on IO Server Config then select the required IO Server:

You will find in the following pages detailed examples on how to configure each of the eWON IO servers and Tags to enable the configurable gateway feature.

Enabling the eWON500™ ModbusTCP gateway

The ModbusTCP is activated by default in the eWON500™. Nevertheless, you have to know where to restablish it if it has been unactivated.

• Check that the feature is active by clicking on Main menu from the eWON500™ menu bar, then select IO Server Config/Modbus and Edit. Activate the eWONServer checkbox if required.

• The Modbus TCP Unit Address is set to 100 by default. You can modify this value if e.g. this address is affected to another device on your industrial network. Don’t forget to click on the Update Config button to validate your changes.

SNMP publication

• First of all : you’ll find the MIB file of the eWON on the Download Software page on eWON.biz.• To publish a tag in SNMP, in the Tag Setup page of the tag, you only need to enable the

SNMP publication with a defined OID (Object IDentification).

User Guide

Rem: the SNMP publication and the ModbusTCP publication are independent and thus can be enabled at the same time.

The eWON500™ doesn’t act as SNMP server by default, you need to enable it and configure it correctly.

Go on the menu Config/System Setup/General/SNMP to enable SNMP on the eWON500™.A simple configuration is shown below:

You can restrict SNMP access to specific hosts by disabling the Accept SNMP from any host checkbox.

• Click on Add/Update Only to validate the Tag configuration

At this stage, we are able to read the value from the Tag on the PLC, providing the MW0 word matches a running program in the PLC. The Technical Note 15: Gateway XIP - Unitelway for Schneider PLC you can download from the eWON web site http://www.ewon.biz (Support/Documentation/Technical notes) explains how to create such a program from PL7 Pro, then transferring it from PL7 Pro to the PLC. For the moment, the eWON is connected to the PLC through its serial link; now we are going to read the value in the eWON (Main Menu/View I/O). Providing the serial connection works and the program is running on the PLC, you should see the Tag value changing in the View I/O page (click at regular interval on the Update link to see the value changing).
