1 Introduction
The IP-EFOY-GATEWAY serves for remote control of a single SFC EFOY PRO fuel cell over the TCP/IP protocol.
At this the entire fuel cell parameter defined by the SFC EFOY PRO technical data sheet are readout continuously over the RS232 interface. These data sets are provided to the customer for control application in different formats.
• SNMP
• XML
• HTML web site
• Email
• TCP-UART-Bridge-Mode (direct EFOY Pro remote command line interface terminal)
• TCP socket services can be developed on request
Furthermore, the IP-EFOY-GATEWAY gives the customer the opportunity to set up/reconfigure the EFOY PRO
fuel cell either within a local area network or over the internet by using the web site. There is no need for
further software installation.
The customer benefits from a simple and intuitive web menu navigation to preconfigure the fuel cell ex ante
or in a live running system.
However, the greatest benefit of the IP-EFOY-GATEWAY solution is that it makes it possible to give your
EFOY PRO fuel cell an IP address and that it can be integrated in a given IP network very quickly without any
limitations. From now on statically scheduled service tours are minimized and can be coordinated much
better since EFOY PRO fuel cell's parameter/states may be retrieved from each location and 24 hours a day.

8 Getting started
Figure 3 depicts schematically the cabling diagram of the IP-EFOY-GATEWAY to other communication devices
and EFOY PRO periphery.

[email protected] | www.awilco-multiplex.dk
As a start please follow the following steps to set up the network configuration properly. The IP-EFOYGATEWAY's default IP-Address is “192.168.96.210”.
Use your browser on initial installation or after a default reset to access IP-EFOY-GATEWAY's web server.
First you have to set up network settings to be conform with your local network.
1. Connect the IP-EFOY-GATEWAY RJ-45 interface labelled with “ETH” with the grey cable to your PC's
network interface
2. Reconfigure the IP configuration under menu “Internet protocol version 4” of your PC's network
interface and then press “properties” (see Figure 4)
3. Choose the following IP configuration for your PC (see Figure 5).

[email protected] | www.awilco-multiplex.dk
4. Open the browser and enter the default IP address of the IP-EFOY-GATEWAY (see Figure 7).
5. Choose menu item “IP” on the left of the website and enter the default login and password co m-
bination (see Figure 6 - Default user name: “admin” and default password: “00000”)
6. Afterwards choose new static IP-Configuration for your given network (see Figure 7). If you set the
“DHCP” check box, the IP-Configuration may be accomplished by a DHCP server in the local network automatically.
7. Now you may disconnect the network cable from your PC and reconnect it to a router or wireless
router.
8. Now please open your browser again and enter the IP-EFOY-GATEWAY's IP-Address previously con-
figured under item 6
9. Now you should have access to the web server over your local network

10.10 Email Notification Service
From firmware versions v0.6.1 on, the IP-EFOY-GATEWAY supports an email notification service to deliver
EFOY PRO events and warnings to an email address. From now on service personnel get real-time email fault
reports on their smart phone or email account. The service is set up the easy way over the website menu
“Notification” (see Figure 22). The user just needs to have a valid email address and an email account login
for the email server.
The following EFOY PRO events are delivered to the preconfigured email recipient via an email fault report
(see 20).

Emails of the IP-EFOY-GATEWAY can be fetched with a default email client software like Microsoft Outlook,
Mozilla Thunderbird (see 22) or a Smart-Phone.
Figure 27 depicts all fetched fault report emails in the area marked with „1“. Area „2“ shows the delivered
IP-EFOY-GATEWAY emails with the fault report in more detail. 22 illustrates the email fields and the single
rows of the fault report.

10.11 TCP-UART-BRIDGE-MODE
Remote control over a command line interface is also possible. Figure 26 depicts the opportunity how to
establish a remote connection to the IP-EFOY-GATEWAY over terminal software like Hyper term, Tera term.
To use this option, a service (TCP Service Port) has to be started first over the web interface.

10.12 Off-the-shelf SNMP based monitoring solution
Figure 27 shows customer's IP-EFOY-GATEWAY implementation using an SNMP based monitoring solution.
Doing so it is possible to manage all EFOY PRO installations at a glance. This solution is especially intended to
be used by „blue light“ organizations, telecommunication provider, surveillance provider, as all critical IP
data can be secured by the customer himself. So the customer doesn't rely on any third party portal solutions and security can be assured on demand.
The following network map shows a rough overview of the entire network infrastructure. I.e. the monitoring
solution is not only intended to be used for IP-EFOY-GATEWAYs, also all other network equipment e.g. cameras, router, switch, server... can be monitored, in general all devices having an IP address and of course all
products deployed by Ingenieurbüro Piwek.
If an EFOY PRO is in error state, or running out of methanol, the IP-EFOY-GATEWAY on the tactical map lights
up red. The operator is now able to react very quickly within few minutes.

Figure 29 shows additional EFOY PRO information in graphical charts. So you can see the entire fuel cell
behaviour over time.
• Battery voltage
• Charging current
• Fluid level
• Output energy
• Temperatures stack, heat exchanger, fuel cell
Customer's feedback:
Here’s the host screen showing the voltage/current, output energy, service fluids and temperature levels.
In addition to these, we also read out the Cartridge Sensor and Error Messages. Based on the results we get
via SNMP we added triggers for those. So whenever the fuel cell is in error or when the fuel drops below the
sensor level, we get notified per e-mail.
Also, on the tactical map, the IP-EFOY-GATEWAY icon will light up and show the error. By doing so, our personnel can see which fuel cell is in error, what the cause is and what equipment is depending on the fuel cell.
And because we are graphing everything, we can estimate the time before the fuel levels are reaching critical conditions, as we have visual trends for the energy usage of our systems. So we even know how much
time we have to remedy the situation and we can predict maintenance rounds to change the fuel cartridges.
And it also helps us to calculate Service Level Agreements.
We are currently trying out that monitoring software in a special project for the Railroad, Railway Police and
local Police for Crowd Management purposes.

10.13 SNMP EFOY PRO Fuel Cell Remote Control
Due to SNMP V2C network protocol support of the IP-EFOY-GATEWAY, the system is capable of providing a
given set of variables called OIDs, reflecting the EFOY PRO fuel cell's state, to the customers network ma nagement system. Figure 30 shows a chart logged with a free network management system „The Dude“ over
SNMP protocol. At this the blue curve reflects the EFOY PRO battery charging current and red curve reflects
the EFOY PRO battery voltage. Furthermore it shows the charging/discharging intervals over the time in a
detailed manner. Just due to this information the customer is able to react to any events coming up very
quickly. In many network management systems events can be triggered
• If the battery voltage falls below a threshold or if the EFOY PRO runs out of methanol, a SMS or Email is
sent to a service engineer
• If the EFOY PRO operating time exceeds 5000 hours, send an message to a service engineer for EFOY PRO
maintenance
