Basic troubleshooting

To troubleshoot M-Bus meters connected to an PiiGAB M-Bus 810 there are a couple of things to verify.

Here is a list of good tools to use during troubleshooting:

• PiiGAB M-Bus Wizard
• Gettings started PiiGAB M-Bus 810
• MicroMaster USB
• PiiGAB's general M-Bus documentation

IP-address
What IP-address is the gateway using? To have network communication with the gateway you need to setup your computer in the same network as the gateway. If there is an IT section please contact them to receive an IP-address for your computer. With the PiiGAB M-Bus Setup Wizard you can search gateways on the network or ping the gateway’s IP-address to verify if the network communication works.
I PiiGAB M-Bus Wizard kan man söka efter omvandlare på nätverket eller ”pinga” omvandlarens IP-adress för att verifiera att nätverkskontakten fungerar.

f it’s not possible to receive the gateway’s IP-address then you need to setup a new IP-address.
Please see the FAQ on how to do this.

Port
What port is the gateway set to in order for the the M-Bus client to read the M-Bus meters? If you have network connection with the gateway you can find out the port with the PiiGAB M-Bus Setup Wizard.

Starta PiiGAB M-Bus Wizard -> Ändra omvandlarens parametrar -> Anslut via nätverk.

Protocol
What protocol is the gateway set to in order for the the M-Bus client to read the M-Bus meters? If you have network connection with the gateway you can find out the protocol with the PiiGAB M-Bus Setup Wizard.

Starta PiiGAB M-Bus Wizard -> Ändra omvandlarens parametrar -> Anslut via nätverk.

Note: If the gateway uses TCP you might not be able to connect to the gateway with the PiiGAB M-Bus Setup Wizard to read the M-Bus meters. This is due to that another client is connected to the port that the gateway is using. Change the port, change to UDP or turn off the client.

Communication speed
What communication speed is the gateway set to in order for the the M-Bus client to read the M-Bus meters?If you have network connection with the gateway you can find out the communication speed with the PiiGAB M-Bus Setup Wizard.

Starta PiiGAB M-Bus Wizard -> Ändra omvandlarens parametrar -> Anslut via nätverk.

Note: If the gateway is set to 300 baud the communication speed is very slow. Remember to change the timeout in the PiiGAB M-Bus Setup Wizard to handle the long response time.

M-Bus meters
Is there any documentation of what M-Bus meters that are connected to the gateway? What addresses does the M-Bus meters use? (primary or secondary addresses).

If there is documentation of the meters then you can simple check each meter one by one with the PiiGAB M-Bus Setup Wizard. It’s also possible to read the search function in the PiiGAB M-Bus Setup Wizard.

If there is no documentation of the meters then you can use the search function in the PiiGAB M-Bus Setup Wizard. If the the result of the search function is incomplete then you have to find each meter one by one on the site and test them individually by it’s M-Bus address (primary or secondary address).

A M-Bus meter not responding
If an M-bus meter is not responding then you have to test the meter individually. If possible disconnect all other meters and test only that specific meter. Try with primary address 254 or the meter’s own primary or secondary address.

If it’s not possible to disconnect all meters then you can test the specific meter with a MicroMaster USB.
