  • System and a method for synchronization and transmission of information in a distributed measurement and control system
    Patent number: 9356720
    Abstract: A method for synchronization and transmission of information in a distributed measurement and control system, wherein frames, being a sequence of bits, are transmitted between a master node (M) and a slave node (S), the method comprising cyclically performing the steps of: receiving (101) at the master node (M) an echo frame sent from the slave node (S) as an echo of the last frame received by the slave node (S) from the master node (M); determining (102) the time of frame propagation between sending the frame from the master node (M) and receiving the echo frame at the master node (M); constructing (103) a subsequent frame at the master node (M), the subsequent frame comprising a data field comprising a time adjustment dependent on the determined time of frame propagation; sending (104) the subsequent frame from the master node (M) to the slave node (S); receiving (105) the subsequent frame at the slave node (S); and adjusting (106) a timer (S_T) of the slave node (S) depending on the value of the time adjus
