摘要： PURPOSE:To facilitate the generation of a user program including communication control with a personal computer through the use of a public line by providing a public line interface part for a public communication network and transmitting/receiving information in accordance with a private communication instruction written into a sequence program. CONSTITUTION:When the address of a program memory in a user memory 3 is instructed by a program step which a program counter 2 shows, and the sequence program of the corresponding step is read, an instruction code in the program is inputted to a CPU 1, and it is decoded and executed in the CPU 1. A part except for the instruction code is inputted to an input/output interface part 4 or the user memory 3 as an operand. A state value or data is read from the input of a designated number, and it is transferred to an interface part 6 or data is received from the public line interface part 6. The state value is written into designated output and is written into the user memory 3 so as to execute sequence control.

摘要： PROBLEM TO BE SOLVED: To control the direction of outlet air-flow from FFUs (fan-filter units) and the air-flow rate in order to improve cleanliness of the clean room for manufacturing electronic devices such as semiconductors and liquid crystal displays.
SOLUTION: Air-flow direction and air flow-volume in each FFU are controlled on the basis of information obtained from FFU and a differential pressure gauge provided in the ceiling of the clean room. Pressure in the ceiling chamber is made uniform in order to improve the air-flow distribution in the clean room, further the number of rotation of a fan motor of each FFU is made easily controllable. In order to control the direction of air-flow in the clean room, a dumper-regulating mechanism is provided under the floor of a grating in the clean room. Through this constitution, operating conditions of the clean room are optimized and energy-saving is attained.

摘要： PURPOSE:To surely switch a line to a stand-by system when the active system of a duplex constituted processor fails. CONSTITUTION:Whether the processors 1A and 1B are the active system or the stand-by system is discriminated at monitoring circuits 3A and 3B, an AND condition that a line switching instruction signal 7A or 7B is outputted from the processor discriminated as the active system is taken by an AND circuit 4A or 4B and a line changeover switch 5 is operated by the output. Thus, even when a line switching signal is erroneously outputted from the failed processor, since it can be recognized that it is not the active system from the discrimination of the monitoring circuit, the AND condition of the system does not come into effect and the sure switching to the normal processor can be performed.

摘要： PROBLEM TO BE SOLVED: To more flexibly cope with the change of a sequence program by controlling execution corresponding to attributes defined by corresponding information at the time of cyclically executing respective processing units in the sequence program in an order corresponding to a sequence. SOLUTION: An MPU 60 successively cyclically executes only circuits for which an execution code is set to a circuit information code among the respective circuits for constituting the sequence program stored in a user program memory 62. The circuit information code is rewritten by the MPU 60 as required corresponding to an instruction from an external controller 70. Rewrite is executed by receiving the instruction of the rewrite from the external controller 70 for the respective circuits or is executed by receiving the instruction of the rewrite from the external controller 70 altogether for the entire circuits. Thus, the change of the sequence program is more flexibly coped with and the correction and preparation of the sequence program as intended are more easily and surely performed.

摘要： PURPOSE:To reduce the transmission power for a slave station, to reduce the a prescribed load of a master station and to improve the processing performance by sending a elapsed point time to a master station together with data and a time at the point of time elapsed by a setting time from a transmission point. CONSTITUTION:A data comparison section 13 of a slave station remote supervisory controller 14 compares measurement data 10 received from a supervisory control object 9 with a preset elapsed point or transmission point. A control section 4 reads an elapsed point excess time of the data 10 to a data storage section 2. When the data 10 exceed a transmission point, a supervisory timer 6 is started and after the timer expires, when the transmission point is exceeded again, the time is set to the storage section 2. Then the storage section 2 outputs the stored time and the data 10 to a data transmission section 7, which sends them to a master station remote supervisory controller.
