Abstract: The present invention provides a mechanism capable of creating, in a simplified manner, a safety program in accordance with a safety use. A program creation assistance device assists in creation of the safety program to be executed by a safety controller. The program creation assistance device selects a safety use of the safety program to be created in accordance with user input, determines, based on the safety use selected, an input block to which a safety input signal from an input device is assigned and a functional block that implements a safety function suitable for the safety use selected, the input block and the function block making up the safety program, provides an unfinished safety program in a programmable manner, the unfinished safety program including the blocks determined, and supplements the unfinished safety program to create the safety program in accordance with user input.

Abstract: The present invention provides a mechanism for adding a disabling function that satisfies a safety standard to a safety program in a simplified procedure. A program creation assistance device that assists in creation of a safety program to be executed by a safety controller creates a safety program including an input block to which a safety input signal from an input device is assigned, a functional block that implements a safety function, and an output block that outputs a safety output signal, and adds, to the safety program created, a plurality blocks and connections between the plurality of blocks in accordance with an instruction from a user, the plurality of blocks and the connections between the plurality of blocks being configured to implement a disabling function that disables the safety input signal when a predetermined condition is satisfied in the safety program.

Abstract: It is possible to perform prompt and accurate diagnosis of a pneumatic device while mitigating a burden on a user at the time of introduction. A flow sensor includes: a flow rate measuring element for measuring a flow rate of a working gas in a pipe; a pressure measuring element for measuring a pressure of the working gas in the pipe; and an evaluation unit that determines a characteristic amount indicating an operation of the pneumatic device based on a combination of the flow rate measured by the flow rate measuring element and the pressure measured by the pressure measuring element, and evaluates the operation of the pneumatic device based on the determined characteristic amount.
