General1
1.1 About this manual
This manual will hopefully give you the guidance you need to connect the
Ethernet/ 810 M-Bus gateway to your network. This manual also describes how
the software M-Bus Wizard, Device Installer, and Com Port Redirector works.
These software programs are on the attached CD or you can download them from
our WebPages.
1.2 Function overview
The PiiGAB 810 gateway is working like an interface between Ethernet and the M-
Bus wire. The gateway is transparent, which means that the questions asked
through the Ethernet are being forwarded onto the electrical M-Bus interface. The
same applies to the answers from the meters that are being sent over the
Ethernet to the superior system. The gateway also works as a pure serial M-Bus
gateway.
1.3 Benefits and possibilities
The gateway can be used on either 10 or 100 Mbit network.
The possibility to choose between TCP/IP or UDP/IP
SNMP for network surveillance
The gateway can be used with a fixed IP or a dynamic IP via DHCP
It is totally independent from the operating system, which means it can be
used both by Linux and Windows.
If there is a need for high safety in the network the data traffic can be
encrypted with up to a total of 256 bites. This is an extra, which you need
to request before ordering.
Can work as TCP client or server
The possibility to set a password to prevent unauthorized to change the
configuration.

Technical structure2
The interface of the gateway consists of an Ethernet connection, a serial port, four
parallel outputs for the M-Bus connections, and a connection for voltage supply.
There is also a possibility to connect a safety earth when the gateway is being
used in environments with a lot of disturbance.
On the front of the gateway there are three diode lamps that are indicating the
voltage feed, transmit and response of the M-Bus messages. The voltage diode
lamp has different behaviors depending on normal running, short circuit, or
overload of the M-Bus loop.
2.1 Connections

2.2 Indications
There are three diode lamps on the gateway Pwr, Tx, and Rx.
The Pwr diode lamp provides three different types of information. The red power
diode normally has a firm red light. If the power diode flashes at a 5 Hz frequency
there has been a short circuit on the M-Bus loop. If it flashes at a lower frequency
(1 Hz) the loop has been overloaded. The M-Bus gateway is available as either a
20 or a 60 device master. If those numbers are exceeded there will be a lower
frequency flash.
The Tx diode lamp has a flashing green light when the gateway is sending out a
question onto the M-Bus loop.
The Rx diode lamp has a flashing green light when the gateway receives an
answer from one of the meters connected to the M-Bus loop.

2.9.5 Adapter 4 and 5: Spy
All the traffic that are being sent and received on the M-Bus port are mirrored to
the serial port. This results in that you can connect a serial analyzer or monitoring
software. To be able to read what is being written and read two communication
ports are demanded on your computer.
Through using adapter 4 and 5 monitoring can be done. Adapter 4 is used to
monitor the question and adapter 5 is used to monitor the answer.
The two adapter’s module cables are connected via a branch and onto the
gateway’s RJ-12 contact.

Get started step by step3
This chapter covers the different steps needed to put the M-Bus 810 gateway into
operation.
3.1 Necessary information
The connecting of the supply voltage and the M-Bus loop is made according to table
2.1.
3.1.1 Hardware address
You have to know the unit’s hardware address, which is the same as the MAC
address. The MAC address can be found on the label on one of the gables of the
unit. It has the format 00-20-4a-xx-xx-xx, where xx is a unique number for the
unit.
3.1.2 IP Address
Most of the time the gateway needs a unique IP address on your network in order
to be connected to the superior software. You can also use the automatic IP
address via DHCP if you wish. Contact the system administrator to receive the
right IP address with the belonging subnet mask and gateway. The IP address has
to be within the allowed area, unique within your network, and it has to be in the
same subnet as your PC.
3.1.3 TCP/UDP
To communicate with the superior software you have to choose between TCP or
UDP.
We do not recommend that any of PiiGAB’s products or products bought from
PiiGAB should be made public on the internet. We always recommend that a
firewall is used, not following this recommendation will be at your own risk.
3.1.4 Port number
To communicate with the gateway the port number has to be adjusted. The
default adjustment in the gateway is 10001 and can almost always be used.
Control with the network responsible what port number to use.
Chapter

T H E M O D E R N M - B U S T E C H N O L O G Y
PiiGAB Process Information i Göteborg AB
13
810M.E.1.14
3.2 Using M-Bus Wizard
By using the M-Bus Wizard you can set the IP address and all other important
parameters to be able to communicate with your M-Bus meter. The M-Bus Wizard
is described in chapter 4.
You can search for 810-units in your network through the Wizard. There is usually
an IP address positioned on the gateway and if the address is outside the
permitted IP address area this will be marked in red. If you still are having trouble
finding the gateway on the network you can search and configure the gateway
through the MAC address. You cannot find the gateway if it is connected to a sub
network.
3.3 Adjustments for TCP/UDP and port number
To adjust the TCP alternatively UDP the M-Bus Wizard is used, and it can be found
in chapter 4. Choose “Change Device Parameters” from the main menu and click
through to the site where you make your choice. At PiiGAB we recommend usage
of UDP if this is supported by the superior software. The reason for this is that the
M-Bus driver has complete control over how the questions and answers are being
sent.
The adjustment of the port number is made at the same place as the TCP/UDP in
the Wizard. The port number has to be the same as in the calling from the
superior software in order for contact to be established with the gateway.

810M.E.1.14
3.4 Communication toward meters
3.4.1 The right communication speed
After the right IP address has been established the M-Bus loop’s communication
speed has to be adjusted. The communication speed adjusted in the Wizard has to
match the meters communication speed. Many meters have a communication
speed of 300bps at delivery. If there is a possible to set the meters at 2400bps try
to do that in order to increase the communication speed and by that improve the
performance.
When communication toward the meters has been established and by that the M-
bus loop is connected the right way, you can continue to configure the superior
software.
3.4.2 Adjusting the meter’s communication speed
In version 1.0 of the M-Bus Wizard you can control the meter on your M-Bus loop
directly via the meter’s primary address. You can also adjust functions such as
communication speed and primary address via your network. Note that some
meter makes do not support the possibility to change for example the primary
address via a standard M-Bus command.
3.4.3 Manufacturer specific configuration software
If you want to configure the meters via the meter delivery’s own software you can
do so in most cases over the network via the gateway. They usually have no
network support, so they communicate only via the communication port on the
computer. By using Comport Redirector, described in chapter 8, you can usually
use this software in your network.
3.4.4 Important parameter adjustments
Some issues to keep in mind regarding communication between the meter and the
superior software is the time interval between the questions, the number of
telegram that can be read by the meter, and what communication speed that has
been chosen. Some meters has up to 40 telegrams that can be read at a adjusted
transference speed of 300bps, and therefore take along time.
The M-Bus driver for the SCADA program Citect, which has been developed by
PiiGAB, is documented with great details regarding how different
parameters are being set in programs like NrOfTelegrams, InitRead etc. The
document “Citect for Windows, Version 5.xx, 6.xx M-Bus driver, User Information”
(Version: 1.01.03.001-1) is available to download at the PiiGAB website.

M-Bus Wizard4
M-Bus Wizard is a software delivered with the gateway. The software helps you to
make required adjustments in the gateway to establish communication etc. It also
gives you the opportunity to change address and communication speed on the
meters that supports the M-Bus standard, additionally you can see some parts of
the communication towards the meter.
4.1 Starting M-Bus Wizard
Copy the zip-file ”MBus 800 Family Setup Wizard 2.0.1.zip” to the appropriate
folder on the computer and open the file. Install the program by double clicking on
the Setup files or go via the control panel. After the program has been installed
you can start it by choosing the program in the start menu. If the installation has
been made with the base settings the program can be found under the PiiGAB
folder.
The first time you start the program you have to choose a language. If you later
want to change to another language it is also possible.
After the language has been chosen, the introduction picture is presented with a
summary of the M-Bus Wizard usage.

4.2 Finding the gateway and change IP address
Figure 4-2. Select what you wish to do
The next page (main menu) shows the different commands that can be made with
the M-Bus Wizard. Choose your option and click “Next.” If the gateway has not
been configured before choose Change device IP Settings and click “Next.”
Figure 4-3. Change IP settings –select connection method
In this picture you are choosing the way you want to communicate to install the IP
address. If 810 is connected to the network choose the option on top and with a
serial connection pick the lower. In this part we are assuming that the gateway is
connected to the network. On the side of the gateway there is a label with the

T H E M O D E R N M - B U S T E C H N O L O G Y

810M.E.1.14
MAC address, which is filled out according to the picture. Click “Next” after this. If
the configuration is made via the serial port use adapter 2, see chapter 2.8.1.
Follow the Wizard instructions to co figurate this way. The difference to configure
via the network is that the voltage has to be turned on and off in order for the
settings to have an effect.
Figure 4-4. Change IP settings –enter new IP settings
Fill out the fields, IP-address, Netmask, and Gateway. If you are using DHCP
choose the upper option otherwise choose the lower. If you are going to use a
unique IP address contact the responsible for the network in order to get the
correct information. Click on “Next” to continue.

This picture is solely here to inform you about that the next step is to activate the
earlier made configuration like IP-address, subnet mask, and gateway address.
When you click on “Apply” the configuration starts. When the gateway is updated
with the new information click “Next” to continue.
If you already know that the gateway has an IP address that can be found via the
network choose Find Devices from the main menu as the first step instead. If the
unit is found on the network you do not have to provide MAC-number when you
are setting the IP address. Sometimes it can be hard to find the gateway and the
reason for that can be because it is in a subnet. Contact the network responsible
for further information about the network.
Figure 4-6. Outside permitted address area
If the IP address can be found outside the permitted address area, but is possible
to reach within the network, this is shown in the Wizard (see above.)
Figure 4-7. Network search complete
If the gateway can be found within the network you can see it in the above
listings. Choose the preferred meter and click “Next” to go to the main menu.
