Note: this Quick Start Guide applies to REX 300 systems with order numbers ending in 02

(e. g. 700-872-UMT02). There could be differences in functionality in REX 300 devices with

order numbers ending in 01.

Quick Start Guide REX 300 3

Cabling and PC Settings

1. First, wire up the REX 300 with a supply voltage of

10-30 VDC.

Note: if you wish to use the myREX24, continue on

page 6.

2. By default the REX 300 uses a static IP address

(IP: 192.168.0.100, subnet mask: 255.255.255.0).

Note: when the REX 300 is to be connected into your

company network, rst check with your network admini-

strator that this address is compatible with your network

and that it is available for use.

3. If you must rst change the address of your PC in order to reach the web interface of the REX 300, carry

out steps A to C next. These steps are not necessary when you want to load an existing conguration from

USB. Further information about loading is available on page 7.

–

A) The REX 300 is delivered with the IP address set to 192.168.0.100. Therefore, you must assign your

computer an address in the same subnet.

This applies not only to the IP address but also to the subnet mask.

To make the necessary changes, open the properties of your LAN connection.

Windows XP: Start -> Control Panel -> Network Connections.

Windows 7: Start -> Control Panel -> Network and Sharing Centre -> Change adapter settings

B) Open the properties of the network connection that

is to be used for establishing a connection to the

REX 300. Under “Properties“ of the “Internet Protocol

(TCP/IP)“, modify the IP address of your computer.

C) The IP address must be in the “192.168.0.x“ address

range (subnet). The subnet mask must be identical to

that of the REX 300 (255.255.255.0).

Quick Start Guide REX 3004

Accessing the Web Interface

2. Start a browser (Internet Explorer, Opera, Firefox, ...)

and enter the IP address of the router in the address

eld.

3. In order to register with the REX 300, enter the

following data:

User name: helmholz

Password: router

Note: for security reasons, the password of the router

should be changed as soon as the router is congured;

this also applies to the “root“ user.

4. Using the menu item “System“ -> “User“, usernames

for logging in at the REX 300 can be created, edited or

deleted.

The user rights can also be assigned here.

5. When necessary, the IP address (LAN address) and the subnet mask of the router can now be congured

via the menu item “Network“ -> “LAN“. The router is accessible in the LAN network via this IP address.

Note: if the IP address is to be changed, it must correspond to the address range (subnet mask) of your

computer. See steps A to C on page 3. After making the change, restart the REX 300.

1. Connect the LAN interface of your computer to the

LAN interface of the REX 300.

Use the cross-over cable supplied for a direct

connection between your PC and the REX 300.

Quick Start Guide REX 300 5

Conguration via Integrated Install Wizards

When you wish to use the REX 300 without our myREX24 mediation server, the device can also be set up

using the install wizards integrated in the web interface.

Access this in the web interface via the the “Wizards“ menu item in the upper right hand corner.

The following install wizards are integrated in the

web interface:

• LAN Settings

(for conguring the LAN interface)

• Internet connection

(for conguring the Internet connection)

• VPN

(to set up a VPN tunnel)

Note: with a VPN, before starting the VPN install wizard,

decide whether the OpenVPN or IPsec VPN install wizard

should be started.

Quick Start Guide REX 3006

Conguration via myREX24

Logging in

In order to use myREX24, login under

www.myREX24.net -> “Request access“.

Fill out the elds required there.

After “Send“ing the form you will receive your access

data by e-mail.

Under “www.myREX24.net“ -> “Support“ -> “Down-

load“ use this access data to download the necessary

software (shDIALUP) and an application example.

Logging in at the Portal

As soon as the shDIALUP software has been installed

and started, you can use your access data to log into

myREX24.

Note: your login name must follow the layout “user

name“@“company name“.

Example: admin@helmholz

After logging into the portal, additional users can be set

up under “User“.

Creating a system conguration

Read the application example.

This is available at “www.myREX24.net“ -> “Support“ -> “Download“.

Downloading a system conguration

After a conguration has been entered, this can be stored on your PC by pressing the Floppy Disc symbol.

Import a system conguration

Finally, import the system conguration into the REX 300. There are two ways of transferring a

conguration into the REX 300. For further information, see page 7. After a system restart and, dependent

on the conguration, the REX 300 registers with myREX24.

Establishing a connection

A connection to the system can only be established to the myREX24 web interface using shDIALUP.

For more precise details see page 8 or the application example.

Quick Start Guide REX 300 7

Importing Congurations via the Web Interface / USB

Web interface

1. Open the REX 300 web page - see the description “Accessing the Web Interface“ on page 4.

2. Via the menu item “System“ -> “Import/Export“, open the page where you can read in the REX 300

equipment conguration.

3. The option “Restore the Conguration“ is on this page. Using “Search“ select the appropriate le on

your local disc.

4. Now press the “Restore“ button. Next you will be asked which conguration category you wish to

restore; press “Restore“ again. After a short conguring delay, a system restart will activate the REX 300

conguration.

USB

1. Load the suitable conguration le onto a FAT formatted USB stick.

2. Plug the USB stick into the USB socket on the REX 300.

3. Follow the steps for loading the “Factory Settings“ described on page 9. If the USB stick contains a valid

REX 300 conguration, this will be loaded from the stick.

4. As soon as the Rdy LED is ON continuously, the process is complete and the system conguration will

have been activated.

Note: if a conguration is to be loaded from a USB stick, it must be located in the root directory of the stick

and have either of the following names:

autocong.mbn

myREX24.mbn

Quick Start Guide REX 3008

Establishing a Connection via myREX24

1. Using the shDIALUP software and your access data,

connect to the myREX24.

2. Here you will see the REX 300 that you have congured. When a REX 300 is logged into the portal, this

will be marked with a green circle.

3. When you want to connect to one of your systems, you can use either the “Connect“ button or the

“QuickConnect“ button to establish the connection.

4. After the connection has been established, all IP packets that are valid for the local LAN network

will be forwarded.

5. When your maintenance work is complete, disconnect using the “Disconnect“ or “QuickDisconnect“

button.

Note: if, during this process, a USB stick with conguration data is plugged in, this data will be loaded from the

USB stick and activated.

The complete conguration details have now been deleted.

The REX 300 is now reset to its factory settings and can be congured anew.

Important: the IP address of the REX 300 is set back to 192.168.0.100.

Quick Start Guide REX 30010

Remote Maintenance of an S7-MPI/PROFIBUS-PLC

In order to reach an S7-MPI/PROFIBUS-PLC with a REX 300, the following steps must be carried out.

(not for REX 300 eco)

1. Install the NETL ink®-S7-NET driver, either from the accompanying CD or download the latest version

from the Internet at www.helmholz.com.

4. After this step, the system can be worked on from the S7 software.

2. During installation of the driver, add the interface

“NETLink®-S7-NET PRO Family“. After this, the REX 300

can be used from the PG/PC interface.

3. Next, open the PG/PC interface and select the

properties of the NETLink® PRO Family.

New routers can be added in the register

“Local connection“ using the “New“ button.

Enter the IP address and the name of the router. If

either a VPN connection or myREX24 are to be used,

also enter the LAN IP address of the REX 300 here.

Note: by default, in a REX 300, the ports required for

communication are enabled by the driver. These settings

are in the menu “Interfaces“ -> “MPI/PROFIBUS“ ->

“unlock ports in the rewall“.
