From version 4.1.5
M-Bus Communication Driver is now part of the Reliance 4 native communication driver list. This driver is designed for devices that communicate via the M-Bus (Meter Bus) protocol. This protocol is primarily used by devices designed to measure the consumption of heat and also of water, gas, electricity, etc. The driver supports the SND_NKE communication function for the initialization of communication and the SND_UD2 function for reading current data. Usually, the device is connected via serial port, over the RS232/MBus converter. The Ethernet/Mbus converter can also be used with the Reliance 4 system. For this type of connection, the parameters of serial link can be set using the NVT protocol.
