Kieback & Peter does not send list of states of the Schedule block, which results in insufficient definition of the Schedule block when importing into Vision. It is not possible to see the status neither set the value. To fix this, set the states manually in the data point definition in Vision: in our example the states were Day = 1, Night = 2, Off = 3.
The Building Automation Control Network (BACnet) protocol is not new to building management systems. In process stations, however, it appears only gradually, especially for its not quite easy implementation. Unlike relatively simple communication protocols such as Modbus, BACnet defines a number of services and objects that make it easier for application engineers to work with programming and commissioning technologies.
