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： PURPOSE:To average the execution timing of each control loop and to uniformalize the response delay of sequence control by discriminating the execution timing of each loop under a condition that the number of continuous system control loops executed in a designated cycle can be minimized when the control of the continuous system control loop is executed. CONSTITUTION:The area length of a scheduling table 201 is set in accordance with the least common multiple of a ratio of timer inter-ruption cycle that is the generating cycle of an execution cycle to a sampling cycle that is the execution cycle of each PID loop. Data of loop number is stored in areas 1-m corresponding to the generating timing of timer interruption as the data to specify a PID control loop set under the condition that the number of PID loops executed in the generating cycle of the timer interruption is minimized. Thereby, it is possible to uniformalize the response delay of the sequence control.

摘要： PURPOSE:To operate a whole control system without any contradiction even when a process interruption is inputted in an optional state by setting a specific instruction which identifies the start of a relay sequence circuit and permitting the process interruption only when the instruction is read out. CONSTITUTION:When an interruption request is inputted from a process, a flip-flop 61 is set and when a signal which indicates a relay sequence head circuit is inputted from a control line (c) in this state, an interruption request a' to an arithmetic part 2 is outputted in the period. Then, when the control line (c) is reset, i.e. when an instruction except a relay sequence head circuit instruction is read, the flip-flop 61 is reset, so that the signal a' is never outputted after this resetting even if a signal (c) is inputted before a signal (a) is inputted. When an interruption acceptance mode select input (d) goes up to a level H, on the other hand, an AND gate 65 is opened on condition that the signal (c) and the output of the flip-flop 61 are both at the level H, so that the request a' is outputted through a OR gate 67.

摘要： PURPOSE: To secure the application of a programmable sequence controller to any type of controlled system by reducing satisfactorily the scan time of the sequence controller with use of an image memory and at the same time coping with a desired controlled system in a satisfactorily short answer time less than a single scan time.
CONSTITUTION: When the input/output control instructions (I/O set and reset instructions) are supplied through an arithmetic part 3, the control lines (set and reset lines) delivered from an instruction decoding part 31 are changed. The set and reset lines are connected to the set and reset inputs of a flip-flop 43 respectively at an input/output control part 4. Then the output of the flip-flop 43 is changed every time the IOC set and reset instructions emerge and then supplied to a data selector 42. Thus the selector 43 selects the external input/ output data given directly from an input part 6 and an output part 7 or the data given from an input/output image memory 41 and sends it to the part 3.

The device 14 includes a symbol display part 50 for display of symbols supplied from the input means and a code display part 51. A liquid crystal structure 52 showing a contact and its nearby connection constitution within the part 50 shows the make, break contacts, etc. and also that the code is not supplied yet to a contact symbol according to the light emitting state of each segment. A liquid crystal structure 65 showing a relay in the part 50 displays the type of a relay in response to the types of characters within the brackets. The part 51 consists of many dot segments and can display the Roman characters and numeric characters as well as the codes of contact, relays, etc.

摘要： PURPOSE:To attain a high-speed response with a sequence controller by adding an arithmetic part and a program area for control of said arithmetic part to a controller part of an extension unit. CONSTITUTION:A basic unit 8 contains a storage part 8a, an arithmetic part 8b, an input part 8c and an output part 8d. A controller part 1 of an extension unit 3 transmits the data given from the unit 8 to an external I/O module 10. Then a single chip microcomputer 6 consisting of a RAM 2, a processor 4 and a ROM 5 is added to the part 1. Thus a controller 7 writes the data given from the unit 8 to the RAM 2 to complete the transfer of the external output data. The external input data is used to read the data out of the RAM 2 and transfer it to the unit 8. Thus an operation is carried out within the unit 3 in parallel with transmission of the external input signal to the unit 8. The result of this operation is delivered to outside.
