This manual applies to the Han2MBus program version 0.99.00beta14
Manual version 2019-12-17
The Han2MBus reads from Han meters and converts the telegrams to M-Bus. The Han meters electrical interface is M-Bus master. The meters must therefore be connected to the Pi-900S M-Bus Slave ports. Pi-900T does not support Han meters.
Pi-900S has two M-Bus Slave ports and supports two Han meters, Hanmeter1 and Hanmeter2 which are hard connected to MBusSlave1 and MBusSlave2 respectively if enabled. A disabled port can be used for other processes.
The M-Bus port can be set up as an ethernet or serial port. It is possible connect a Han meter to one M-Bus Slave and read the M-Bus telegram via the other M-Bus Slave port.
Han2Mbus supports three meter types, Aidon, Kaifa and Kamstrup. No user configuration is needed for the meters.
The following meters have been tested to work correctly:
| Kamstrup: |
|---|
| Meter Type: | Han Meter type. Aidon, Kaifa and Kamstrup are supported. |
|---|---|
| Enable: | Set to YES if a Han meter is connected. If not enabled, the port can be used by other programs. |
| Com port: | HanModule1 is hardcoded to the MBusSlave 1 port. HanModule2 is hardcoded to the MBusSlave 2 port. |
| Baud rate: | Set to 2400 for all supportet meters. |
| Bit number: | 8 bits for all supported meters. |
| Parity: | Parity of serial ports. |
| Stop bit: | 1 or 2 stopbits for the serial protocol. |
| M-Bus Primary Address: | |
| M-Bus primary address for the Han meter. Can be set to 1 to 249. Default is 241 for HanModule1 and 242 for HanModule2. | |
| M-Bus ID: | ID part of secondary address. User definable. Should preferably be set to the ID number printed on the Han meter. Possible values 1 -- 99999999. Eight digits. |
| Type: | Port type. Can be set to UDP, TCP, Serial. If serial, available values are RS-232, RS-485 and M-Bus Slave. If M-Bus Slave port is selected, the port cannot be used for a Han meter. The default value is UDP 20002. This will connect the Han2MBus program directly to one of MBusHub masterports. |

Important. The Han meters have different serial setup.
