M-Bus Extension CardΒΆ

M-Bus Extension Card for Bithouse Integral controller provides 1 M-Bus bus per card. When a card is installed in the Integral controller, a new serial device will be added by the operating system. The serial devices can be referred by custom names that are determined by the slot the card has been installed. All internal Extension Cards will appear under /dev/slots/internal/.

Note

Here internal installation means that the card has been installed to one of the six slots available in Integral controller

The predictable name will use following pattern:

M[slot number]_Mbus_1

Example1:

  • M-Bus Card has been installed in the first slot (Slot 1) and we want to use the bus, the device in ioPort device field would be /dev/slots/internal/M1_Mbus_1

Example2:

  • Modbus Card has been installed in the fourth slot (Slot 4) and we want to use the bus, the device in ioPort device field would be /dev/slots/internal/M4_Mbus_1
