摘要： PROBLEM TO BE SOLVED: To provide a new line switching device for suppressing damages to a line fault, to a minimum, improving the availability, and enhancing cost-effectiveness in the system as a whole, and to provide a plant control system which uses the device. SOLUTION: The line switching devices corresponding to each input/output device are arranged in order to control the plurality of input/output devices with the use of a single CPU. An ID is imparted to each line switching device. An ID for uniquely identifying the line switching device is embedded in a data frame to be transmitted from the CPU. By having the line switching device allow only the data frame with IDs matching to pass, collisions of the data frames, which occurs when the data frame improperly comes-in to a control line, are avoided.

摘要： PROBLEM TO BE SOLVED: To provide a plant control system with no possibility of malfunction of a device ON/OFF controlled by an LV (Logical Variable) function.
SOLUTION: An operator displays a measuring instrument figure 4 of TAG on an operation screen 3 of a man machine 1 and performs ON/OFF operation. An LV TAG is registered with authority and it is decided from an authority monitoring information table 1E whether an object TAG of an output request is a TAG with authority of output request. Without authority, an alarm pattern is created unconditionally and output operation is performed; with authority, output request monitoring processing checks a right of access and access code. As a result of checking, the authorities coincide, an output pattern is created to perform the output operation; otherwise, the alarm message is created and the operator is informed of abnormality. Consequently, since an unexpected output request is discovered and suppressed, and authority monitoring including, a plant state, and a time slot becomes possible, the malfunction of the device can be prevented, so that the reliability is improved.

摘要： PROBLEM TO BE SOLVED: To solve the problems wherein conventionally, a memory data signal of a CPU of a main system is snooped and is acquired by a CPU of a subordinate system via a matching bus, using a parallel bus, which is thus unsuitable for long-distance transmission because the parallel bus vulnerable to noise is used, data to be snooped are the data to be stored in the main system, and thus the subordinate system cannot be processed simultaneously with the main system, causing delays and resulting at the cost of the response speed of the system as a whole, and a separate function for running a plant, without stopping it at updating of a program is required and which makes the functions complicated.
SOLUTION: In a duplexed control system, data to be snooped by a CPU2 of the subordinate system as a stand-by system from a CPU1 of the main system as an execution system are set as control information from a control target to be acquired by the CPU of the main system, and further, advantageously, the phase of a control period of the subordinate system is made to advance more than the phase of the control period of the main system.
