Title: (EN) CONTROL SYSTEM AND CONTROL UNIT
(ZH) 控制系统及控制单元
Abstract: front page image
(EN) A control system (1) is provided with one control unit (5D) connected to an input/output unit (4I, 4O) connected to a device (2), and the other control unit (5W) substitutable for the one control unit(5D). In the control system (1), the one control unit (5D) establishes a connection with the input/output unit (4I, 4O). The connection system (1) is provided with a decision layer (15W) and a securecommunication layer (12W). The decision layer (15W) decides to establish a connection between the other control unit (5W) and the input/output unit (4I, 4O) when the connection of the one control unit (5D) with the input/output unit (4I, 4O) is cut off. The secure communication layer (12W) establishes the connection between the other control unit (5W) and the input/output unit (4I, 4O) in accordance with the decision by the decision layer (15W).
(ZH) 控制系统(1)具备:一个控制单元(5D),其与连接于仪器(2)的输入输出单元(4I、4O)连接;以及另一个控制单元(5W),其可代替一个控制单元(5D)。就控制系统(1)而言,一个控制单元(5D)确立与输入输出单元(4I、4O)的连接。控制系统(1)具备决定层(15W)和安全通信层(12W)。如果一个控制单元(5D)与输入输出单元(4I、4O)的连接变为被切断的状态,则决定层(15W)作出确立另一个控制单元(5W)与输入输出单元(4I、4O)的连接的决定。安全通信层(12W)根据决定层(15W)的决定结果确立另一个控制单元(5W)与输入输出单元(4I、4O)的连接。
