Abstract

An information processing apparatus, information processing method, and computer readable storage medium are provided. An information processing apparatus (200) for generating a safety program for causing output devices to operate such that safety is maintained if a predetermined condition is satisfied includes: an acquisition unit acquiring an input/output setting (230) that correlates respective input devices with output devices that respond to changes in values of input signals from the input devices from a first input value that is an initial value to a second input value; and a generation unit generating, in a case in which a value of an input signal from any of the input devices defined in the input/output setting (230) has changed from the first input value to the second input value, a safety program for shifting an operation state of an output device correlated with the input device to a safety state.

First claim

an acquisition unit that acquires an input/output setting, wherein the input/output setting correlates respective input devices with output devices that respond to changes in values of input signals from the input devices from a first input value that is an initial value to a second input value; and
a generation unit that generates a safety program for shifting an operation state of an output device correlated with the input device to a safety state in a case in which a value of an input signal from any of the input devices defined in the input/output setting has changed from the first input value to the second input value; and
a provision unit that provides a user interface for receiving a setting operation of the input/output setting,
wherein the safety program is formed from input function blocks, intermediate function blocks, and output function blocks,
the generation unit is configured to generate the input function blocks for the respective input devices defined in the input/output setting, is configured to generate the intermediate function blocks on the basis of the input and output relationships between the input devices and the output devices defined in the input/output setting, and is configured to generate the output function blocks for the respective output devices defined in the input/output setting,
the input function blocks are used to receive the input signals from the input devices, the intermediate function blocks are used to perform logical computation on the input signals from the input function blocks, and the output function blocks are used to perform predetermined computation on intermediate signals from the intermediate function blocks and outputs output signals to the corresponding output devices,
