Building AutomationAnother bus that allows for the implementation of communication devices such as Building Automation , among drivers in the automation system that allows home control CAN is .CAN interface is much higher , more efficient and better protocol on RS485 serial transmission was in the 80 initially for the automotive industry . From the viewpoint of the hardware is working on a differential pair of transmission lines (twisted pair UTP computer - 8) . The maximum bus speed is 1MB / s to 40m of cable and decreases with increasing distance also depend on the quality of cables , interference, etc. . CAN interface operates on the principle of equal devices without host manager - Server . Great benefit from the use of CAN bus communication protocol is the implementation of the CAN and the stack in some microcontrollers , ensure that all low-level error handling , communication protocol , collision , frame transmission, etc. . This causes the hardware ' this entire operation is not borne transmission protocol processor . The processor is limited to pre-processing of data packets received from the CAN interface . Greatly simplifies software development for microcontrollers, and requires no expensive equipment like logic analyzers , oscilloscopes and requires no deep into the layer of hardware and " electronics " and analyze data directly in the pipes flowing . The disadvantage is the necessity of a CAN bus implementation and use of a communication gateway between the CAN and other communication interejsem to control from the outside (panels , Tablets , PC), for example, Ethernet to the system was not closed and burdened with restrictions bus . Another disadvantage of the CAN bus is less than the length and the decrease in velocity with a very long bus lines , which may prove to be a barrier at very large buildings such . hotels , public places , offices , industrial plants especially in the presence of large disturbances .
