In case you don’t have a network with DHCP you can also address your PiiGAB 900 with a static IP-
address. For this you also need to set your computer to a static IP-address.
Note: For this setup you might need to have a cross-over Ethernet cable between your computer and
the PiiGAB 900 gateway. To be safe you can use a network switch between your computer and your
PiiGAB 900 gateway.
This feature is only supported from PiiGAB 900 V2 and PiiGAB M-Bus Setup Wizard 3.1.0.

StartKit3.E.1.13
PiiGAB M-Bus Setup Wizard –M-Bus communication
This section will use PiiGAB M-Bus Setup Wizard to verify if the PiiGAB 900 and RELAY PadPulse M2
responses over M-Bus communication.
1. In the main menu select Test, search and configure meters
2. Press Next to continue
3. Select Connect using network and configure the connection as shown in the picture below
Note: Your PiiGAB 900’s IP-address may not be 192.168.10.183. PiiGAB M-Bus Setup Wizard only fill in
the IP-address automatically as you selected in Find your PiiGAB 900 on your network, step 6.
4. Click Next to continue

StartKit3.E.1.13
M-Bus communication with PiiGAB 900 gateway
PiiGAB 900 gateway contains of an internal M-Bus meter which can be used to read the M-Bus voltage
and M-Bus current on the M-Bus loop. This test will read from the internal M-Bus meter.
Read PiiGAB 900 primary and secondary addresses
1. Configure these options as seen in the picture below
2. Press the Find button
By using primary address 251 the PiiGAB 900’s primary address and entire secondary address are
display in PiiGAB M-Bus Setup Wizard.

14
StartKit3.E.1.13
Read M-Bus voltage and M-Bus current from PiiGAB 900
1. Configure these options as seen in the picture below
2. Press the Read button
Besides providing the user with the raw data package of the M-Bus response from the PiiGAB 900
gateway, the M-Bus voltage and M-Bus current are displayed.
Note: The feature to display M-Bus voltage and M-Bus current is only supported from PiiGAB 900 V2
and PiiGAB M-Bus Setup Wizard 3.1.0.

15
StartKit3.E.1.13
M-Bus communication with RELAY PadPulse M2
RELAY’s PadPulse M2 can handle two pulse meters. Both pulse meters have their own M-Bus
connection. By default, according to EN13757, both M-Bus connections have primary address set to 0.
The image above displays the search window in PiiGAB M-Bus Setup Wizard. You can use it to search M-
bus meters on the M-Bus loop.
In the image above you can see that the PadPulse M2 has two primary addresses both set to 0.
Part of the Identify value can also be found inside the PadPulse M2 itself.

16
StartKit3.E.1.13
Change primary address of PadPulse M2
To start communicating with both pulse meter, one of them must have their primary address changed.
When changing the primary address on one of the pulse meter, the other one will remain on primary
address 0.
1. Configure these options as seen in the picture below
2. Press the Set button to change the primary address on one of the pulse meters

17
StartKit3.E.1.13
The picture above shows that one of the pulse meter now has 1 as primary address.
Read both primary and secondary address from RELAY PadPulseM2
1. Configure PiiGAB M-Bus Setup Wizard as one of the images under
2. Press the Find button to test primary address 0 or 1
3. Try both primary address and make sure there is a working connection to both of them
Further RELAY PadPulse M2 configuration
To further configure RELAY’s PadPulse M2 you’ll require their configuration software MBConf. Please
also see the manual for the PadPulse M2 how configure it. You can find both the manual and the
software in the RELAY’s Tools and Docs CD.

PiiGAB Explorer / M-Bus OPC-server –M-Bus communication
When the M-Bus communication is confirmed with PiiGAB M-Bus Setup Wizard, you may use PiiGAB
Explorer to see what is possible to read from the PiiGAB 900 gateway and RELAY’s PadPulse M2. You can
also use PiiGAB Explorer’s built in OPC-client to read the values from the internal meter in the PiiGAB
900 gateway as well as the information in RELAY’s PadPulse M2.
Try the StartKit3 example project in PiiGAB Explorer
1. Start PiiGAB Explorer
2. Go to File menu and press the Open button
3. Browse to the local folder and open PiiGABStartKit3.xml
4. Go to File menu and press Set As Active Project
This will set the PiiGABStartKit3.xml as the active project for the OPC-server. You may look around in this
project and see a default configuration of PiiGAB 900’s internal meter and RELAY’s PadPulse M2.
For instance look at the configuration for each meter in the project:
Internal PiiGAB 900’s internal meter for M-bus voltage and M-Bus current
PadPuls M2 P1 RELAY’s PadPulse M2 pulse meter with primary address 0
PadPuls M2 P2 RELAY’s PadPulse M2 pulse meter with primary address 1

StartKit3.E.1.13
PiiGAB 900’s internal meter
PiiGAB 900’s internal meter can be used to retrieve the identification (serial number), M-Bus voltage, M-
Bus current and also error status information.
Monitor the internal meter
1. Click the Internal node in PiiGAB Explorers tree structure
2. Press the Start Monitor button or go to Tools and press Start monitor
3. Wait for the Quality field to change to Good
4. Press the Stop Monitor button or go to Tools and press Stop monitor to terminate the
monitor function
5. Wait for the server to properly terminate

Data inside the internal meter
Here is a list of what to read from the internal meter
Note: Tags with (ASCII) in their name can be used with M-Bus ASCII. If you have a Modbus client which
supports strings you may use these tags as well.
Modbus registers and Modbus register list
For the internal meter in PiiGAB 900 there are Modbus registers bound to each OPC-tag. The
configuration of the Modbus registers can only be altered from this point. They will not affect the other
meters’ Modbus registers. But if not correctly configured the Modbus register may overlap each other.
Please see the Modbus register list function in PiiGAB Explorer to verify Modbus register don’t overlap if
you change them.
1. Go to Tools menu
2. Press Modbus Register List
