1 The Configurable Gateway PURPOSE You have just received your brand new! ACT L produces a complete range of Ethernet/Internet gateways also known as Programmable Industrial Routers (PIR). See our web site to get further information about the ewon range. The is a configurable gateway: it can retrieve data from several protocols and publish them as Modbus TCP registers or SNMP registers. The goal of the current document is to teach you how to correctly configure the 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. is just out of the box, you have already powered it ON (12-24VDC) and connected its Ethernet cable. Every ewons are shipped with the pre configured IP address and adm/adm as User Name/Password. Enter 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!

2 The Configurable Gateway ModbusTCP/SERIAL GATEWAY Principles The is a configurable gateway: it enables a connection between a supervisor or an industrial software and the through the TCP link (with protocol=modbustcp). This gateway then allows to read in the 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 The configurable serial port Depending on the serial link which is supported by the target PLC, the serial port dipswitches (left bottom side from the 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 Installation Guide (Configurable serial port chapter) you can download from the ewon web site: ( Support/Documentation/User guides). The IO servers The requires a kind of driver to be able to speak the protocol from the PLC. At this time, the embeds several drivers (called IO servers), each of them can be configured from a distinct configuration web page from the interface: From the 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.

3 The Configurable Gateway Enabling the ModbusTCP gateway The ModbusTCP is activated by default in the. 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 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). Page 3

4 The Configurable Gateway Rem: the SNMP publication and the ModbusTCP publication are independent and thus can be enabled at the same time. The 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. A simple configuration is shown below: You can restrict SNMP access to specific hosts by disabling the Accept SNMP from any host checkbox. Page 4

5 ModbusTCP/Unitelway Gateway The ModbusTCP/UNITELWAY Gateway configuration Serial connection configuration Set up ewon dip switches to RS485 mode (with or without polarization depending on your network type) Connect the serial cable between your and the PLC (see page 14) UNITELWAY IO server configuration Go to the UNITE IO server page: Configuration/IO Server Config/UNITE/Edit COM Setup Topic Setup Baud Rate 9600 Tx message timeout Default Topic A Enabled Parity ODD Force Unitelway V2 Unchecked Global Device Address 0,254,0 (Default) Stop Bit(s) 1 Disable 0,254 translation Unchecked Poll Rate Default (2000) HW Mode Half Duplex ADO Default (4) Master Response timeout Rx message timeout Default Default XWAY Network Station Let empty Click on Update Config to validate the IO server configuration Page 5

6 ModbusTCP/Unitelway Gateway Creating a UNITELWAY Tag - Testing from the ewon500 Go to the Tag Setup page: Configuration/Tag Setup/Create New Tag Tag Page - Main Settings Tag Name e.g. test_unite Page Default Tag Description A free text e.g. MW word on the TSX Micro Tag Page - I/O Server Setup Server Name Select UNITE in the scroll list Topic Name Enter A (The one you have previously created) Address MW0 Type Choose Analog in the scoll list Force Read Only Validate the checkbox ewon value Let 1+0 (default) 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 (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).
