Connects to BACnet MSTP devices slaves to read data. One RS485 trunk with a max of 32 devices is supported. The data and transactions are logged. The log files are available and can be transferred to other computers. Current data can be monitored by remote systems running applications that can issue HTTP or SOAP/XMP GET requests – such applications can be easily developed by end users. Of course, this data is available using an Internet Browser such as Internet Explorer or Google Chrome. Connection parameters, device parameters and data parameters are configurable.


Log records of each read and response transactions are maintained in the file system. Log record with time stamps of data returned by field devices are maintained in the file system. These files are (zipped) human readable data. Log files can be uploaded to a remote PC using HTTP. When file space runs low, the data client overwrites older files.

Data Serving

The current value of any/all data objects reads from the field devices can be monitored remotely using HTTP or XML by using HTTP GET requests or XML/SOAP requests.
