Method for transmitting control commands (F-A100, F-A200) in a computer system, wherein said computer system comprises components at least in form of nodes (A100, A200), actuators (ACT1, ACT2, ACT3) and communication systems (COM1, COM2), wherein said control commands (F-A100, F-A200) are communicated over said communication systems (COM1, COM2) from said nodes (A100, A200) to said actuators (ACT1, ACT2, ACT3), and wherein one, two, or more components (A100, A200, IF100, IF200, COM1, COM2, IF11, IF12, IF13, IF21, IF22, IF23, ACT1, ACT2, AT3) of the computer system may fail to operate according their specification, characterized in that for consistently accepting control commands (F-A100, F-A200) at said actuators (ACT1, ACT2, ACT3) the nodes (A100, A200) and their control commands (F-A100, F-A200) are assigned priorities, wherein a node and its control commands have the same priority, wherein at least two priorities (HIGH, LOW) are used, wherein a high priority node produces high priority control commands (F-A100) and a low priority node produces low priority control commands (F-A200), and wherein the high priority node communicates its control commands (F-A100) over at least two of said communication systems (COM1, COM2) to the actuators (ACT1, ACT2, ACT3) and the low priority node communicates its low priority control commands (F-A200) over one of said communication systems to the actuators (ACT1, ACT2, ACT3), and wherein one of said actuators (ACT1, ACT2, ACT3) accepts the high priority control commands (F-A100) from the high priority node as long as the actuator receives said high priority control commands (F-A100) on any one of the at least two communication systems (COM1, COM2) and in this first case, when it receives a low priority control command from the low priority node, discards the low priority control commands (F-A200), and stops accepting said high priority control commands (F-A100) in case said actuator (ACT1, ACT2, ACT3) does not receive said high priority control commands (F-A100) from any communication system (COM1, COM2) of the at least two communication systems (COM1, COM2) for a configurable duration, and in which second case the actuator (ACT1, ACT2, ACT3) starts to accept low priority control commands (F-A200) from the low priority node. for consistently accepting control commands (F-A100, F-A200) at said actuators (ACT1, ACT2, ACT3) the nodes (A100, A200) and their control commands (F-A100, F-A200) are assigned priorities, wherein a node and its control commands have the same priority, wherein at least two priorities (HIGH, LOW) are used, wherein a high priority node produces high priority control commands (F-A100) and a low priority node produces low priority control commands (F-A200), and wherein the high priority node communicates its control commands (F-A100) over at least two of said communication systems (COM1, COM2) to the actuators (ACT1, ACT2, ACT3) and the low priority node communicates its low priority control commands (F-A200) over one of said communication systems to the actuators (ACT1, ACT2, ACT3), and wherein one of said actuators (ACT1, ACT2, ACT3) accepts the high priority control commands (F-A100) from the high priority node as long as the actuator receives said high priority control commands (F-A100) on any one of the at least two communication systems (COM1, COM2) and in this first case, when it receives a low priority control command from the low priority node, discards the low priority control commands (F-A200), and stops accepting said high priority control commands (F-A100) in case said actuator (ACT1, ACT2, ACT3) does not receive said high priority control commands (F-A100) from any communication system (COM1, COM2) of the at least two communication systems (COM1, COM2) for a configurable duration, and in which second case the actuator (ACT1, ACT2, ACT3) starts to accept low priority control commands (F-A200) from the low priority node.
