1 Introduction

This procedure details the configuration and commissioning procedures for the GPRS/3G/4G communications devices used on the UKPN SCADA network.

A single router has the capability provide communications for up to four RTU devices on site using the Ethernet ports on the front of the router (assuming the ports are not being used by other equipment on site, such as LV monitoring I/O units).

2 Scope

This document only covers the configuration and commissioning of the comms device, the installation procedures for the comms devices are detailed in the relevant RTU/network equipment ECS documents.

Select the correct Configuration file: xxxx.bin

Note there is a bug in Alfresco which means file name may get changed as you download the file. Make sure the filename ends in .bin as you save it to your PC. See Appendix for details.

Download it to a suitable folder on your laptop.

Download the latest Firmware/Software file from Alfresco:

Open Alfresco from the Intranet Home page:

Home Page > Policies, Procedures & Forms > Engineering > Reference Library > Link to: Reference Library > Relay and RTU Software > Multi Tech > Multitech MTR5 router firmware Version x.xx

Select the correct firmware file: xxxx.bin

Note there is a bug in Alfresco which means file name may get changed as you download the file. Make sure the filename ends in .bin as you save it to your PC. See Appendix for details.

Download it to a suitable folder on your laptop.

When upgrading to firmware version 4.12 and a V3 config file, be sure to upgrade the firmware before you install the new config, otherwise you will not be able to log into the router.

The following configuration can be carried out in the office:

1. To configure the router set up the PC set as follows:

Set the PC for a DHCP IP address (the PC is most likely already set up for this).

2. Connect the PC to one of the LAN sockets of the router E1, E2, E3 or E4 (For primary serial RTU configs the E1 port cannot be used, but for all other configs, it can be used) and provide power to the router. Use a web browser to connect to the router using the following URL:

https://192.168.1.1

Note the use of https://

2. Check the Comms Device has the correct latest firmware version installed as available on

Alfresco. If it is not the latest version, update the firmware by selecting ‘Firmware Upgrade’. If the

firmware version in the router is pre v4.12 then the screen will differ from that shown below. In this

case, refer to Appendix A to upgrade the firmware.

3. Select ‘Browse’, then browse to where you have downloaded the file on your PC, then select

‘Upgrade’.

Update can take up to 10 minutes.



Version: 2.0

Date: 03/05/2018


You will see the following screen while the router is upgrading.

The router will automatically reboot.

4. Once the router has rebooted, log back into the router using https://192.168.1.1 (as described in

section 3) and check the Firmware is showing the correct version.

5. Load the required configuration into the router.

Select ‘Configuration Restore’.

https://192.168.1.1/



Version: 2.0

Date: 03/05/2018


Select ‘Browse’. Browse to where you have downloaded the file on your PC, then select ‘Upgrade’.

6. Once the router has rebooted, log back into the router using https://192.168.1.1 and check the

Configuration is the correct version (this is always displayed on the top of screen when logged

on).

7. Input the ‘Site Name’ as appears on Power-On, the ‘O2 APN Username’ and the ‘Vodafone APN

Username’ and click ‘Save’.

https://192.168.1.1/



Version: 2.0

Date: 03/05/2018


The APN User Names (often known as Radius User Name) will be provided by the Power-On

Commissioning Engineer and will follow the following format:

The user name configured in the router must match the username set up in the radius servers – this

will normally be done automatically via Power-On for secondary SCADA (UKPN IP Secondary

SCADA polling). The secondary RTU username format is:

LPN only:

<UKPN area>_<short RTU name>_O for O2 SIM

<UKPN area>_<short RTU name>_V for Vodafone SIM

LPN_12345T1_O

LPN_12345T1_V

NB: short RTU name will always be 7 characters

For EPN and SPN:

<UKPN area>_<RTU alias>_O for O2

<UKPN area>_<RTU alias>_V for vodafone

<UKPN area>_<substation number_installation type >_O for O2 SIM

<UKPN area>_<substation number_installation type >_V for Vodafone SIM

EPN_6R6553_PT_RTU_O (pole top RTU)

EPN_6R6553_PT_RTU_V (pole top RTU)

EPN_6R6553_GM_RTU_O (ground mount RTU)

EPN_6R6553_GM_RTU_V (ground mount RTU)

<UKPN area>_<spens number_installation type >_O for O2 SIM

<UKPN area>_<spens number_installation type >_V for Vodafone SIM

SPN_400017_PT_RTU_O (pole top RTU)

SPN_400017_PT_RTU_V (pole top RTU)

SPN_400017_GM_RTU_O (ground mount RTU)

SPN_400017_GM_RTU_V (ground mount RTU)

8. Power the router off, install a SIM card into the SIM A slot, and power the router back on. After about 3 minutes the router should have restarted and should have authenticated on the UKPN network. The SIM A LED changes from flashing to steady, and remains steady once it has authenticated. When the SIM A LED is steady, the router should have been assigned an IP address.

9. Log back into the router and check the correct IP Address (as specified by the Power-On commissioning engineer) has been populated.

Select ‘View Network Status’.



Version: 2.0

Date: 03/05/2018


10. Check the correct IP address has been assigned, until the correct IP address is obtained, the tool will show 0.0.0.0. Please ensure it is the correct IP address. This page does not auto refresh so you will need to exit back to the main screen and re-enter the View Network Status page to refresh the IP address. To return to the main menu select the ‘Back’ button at the bottom of the page (may need to scroll down).

11. REPEAT THIS PROCESS FOR BOTH THE VODAFONE AND O2 SIM CARDS TO CHECK THE SIM CARDS AND RADUIS SETUP FUNCTION CORRECTLY.

The Network status page also has a ‘Shutdown’ button. This should be used if you need to replace an existing SIM card with a different SIM card while using the same radius account, for example if you are testing several SIM cards in the office using one of the test accounts. This should overcome the problem seen in the past when it sometimes took a few hours for a router to pick up an IP address. Use the shutdown button before removing the SIM card from the router. The issue is that the mobile network forms an association between a radius username & IP address and the physical SIM, which can last for up to 24 hours, so if you replace one SIM with another SIM, the first SIM remains associated with the IP address, so the second SIM cannot acquire the IP address. The Shutdown button tells the mobile network to break this association and then it remains idle so you can power down, replace the SIM with the new one and then power up again.

The following procedure must be carried out on site:

12. Choose which service provider network to use:

Either:

Use a Dycon D2377 4G/3G/2G Signal Analyser (see Appendix C)

OR

Use the MultiTech router. On newer routers (serial number above 40004225A), a more in-depth signal

strength analysis can be performed (see Appendix B), for older routers this option is not available and

the simple ‘Signal Strength’ level should be used.

Follow steps 8 to 11 and ensure the router has the correct ‘APN’ and ‘Radius User’ name for both

Vodafone and O2 and the correct ‘Site Name’.

Install a Vodafone SIM into the ‘SIM A’ slot, reboot the device and note the signal strength. Repeat for

the O2 SIM. Use the SIM with the best overall signal strength. Guidance for using the signal strength

analyser functionality in the router is contained in Appendix B.

If the router is a newer model select the ‘Scan’ button to perform the signal strength analysis, if it is

older and does not have the scan function, note the ‘Signal Strength’ level.

13. If mounting the router on DIN rail: Fix the adaptor plate on the top of the router (remove the

existing 4 x screws and bolt the plate on). Fix the DIN rail mounting bracket on the mounting plate

and mount the router in the RTU.

Appendix B – Signal Strength Analyser Functionality

On newer routers (serial number above 40004225A), a more in-depth signal strength analysis can be performed.

The colouring of the signal strength survey is as follows:

• Green Good signal level – reliable operation. Ideally, there should be at least two

cells from the chosen provider in green.

• Yellow Medium signal level - not ideal but adequate. One or two cells from the

chosen provider in yellow or green is acceptable

• Red Low signal level – not acceptable. If the only O2 or Vodafone cells are in

red, then we need to try a better antenna or change to another form of comms.

The router will use 4G if it is available, and if not it will use 3G and if that’s available it will use 2G. 4G

and 3G give good bandwidth, but 2G has very low bandwidth and is a last resort. In the following

example, O2 is best, but Vodafone would be ok.
