An input/output response relation data storagestores input/output response relations which are inputted by the user and in each of which an I/O station for input and an I/O station for output are defined. For input/output response relations in each of which the I/O station for input differs from the I/O station for output and each of which needs communications between the I/O stations, an interchange searchersearches for an interchange candidate with which to make the I/O station for input and the I/O station for output be the same as a result of interchanging either of the I/O station for input and the I/O station for output with another I/O station, an interchangerperforms an interchange, and a displaydisplays a result of the interchange.

Input/output response control setting device

A workpiece simulation part estimates the amount of movement of the workpiece from drive information and estimates the current position of the workpiece by adding the amount of movement to the previous position of the workpiece, the drive information being generated for, among at least one actuator, an actuator that is assumed to constrain the workpiece under the constraint conditions. A sensor simulation part uses the current position of the workpiece to generate sensor simulation information. An input/output switching part transmits the drive information to the workpiece simulation part and transmits the sensor simulation information as alternate information of the sensor information to the control-program execution part.

Controller and conveyance system

A technique for enabling reduction in user operations. A program generating apparatus includes a control distribution unit and a communication function adding unit. The control distribution unit allocates respective control blocks of a control model to controllers, based on the control model received by a control model input unit, and setting information and connection information received by a setting information input unit. The communication function adding unit adds, when first and second ones of the control blocks are connected to each other, a communication control block to a connected part between the first and second control blocks, the first and second control blocks being allocated to different ones of the controllers in the allocated control model.

Apparatus and method for generating program

When change amount information calculated by a change amount information calculating unit satisfies a start condition and a signal condition is true for an operation instruction the start condition and the signal condition of which are defined, an operation instruction execution control unit determines a start of the corresponding operation instruction and determines operation completion based on a completion condition determined in advance of the operation instruction. An operation instruction executing unit executes the operation instruction the start of which is determined by the operation instruction execution control unit and stops the operation instruction when the operation completion is determined by the operation instruction execution control unit.

Synchronous control device

A programmable controller includes a universal microprocessor. This universal microprocessor incorporates an acceleration section. The control-program-development supporting apparatus generates an execution code directly executable by the universal microprocessor. Thereby, the acceleration section executes sequential processing.

Programmable controller, and control-program-development supporting apparatus

A program executing apparatus such as a programmable controller has a re-structureable address conversion section restructuring an address to generate a new address for specifying bit data that corresponds to each bit position in a physical memory or an I/O memory. Further, a program development supporting apparatus, such as a control program development supporting apparatus, has a conversion tool that generates configuration data describing a detailed restructure indication to enable the program executing apparatus to restructure the address, and a program making access to the restructured address.
