Abstract: An evaluation system includes an acquisition module that acquires a safety program, an instruction extraction module that extracts an instruction directed to processing for causing a target device to operate with safety maintained, a signal extraction module that extracts an input signal and an output signal related to the instruction, a setting module that displays the extracted input signal and the extracted output signal in association with each other, and receives a setting of an expected output value for the displayed output signal, the expected output value being a value for causing the target device to operate with safety maintained, and an evaluation module that changes a value of the extracted input signal and determines whether a value of the output signal calculated by an operation in accordance with the safety program, in response to change of the value of the input signal, is identical to the expected output value.

Abstract: An evaluation system includes a process execution module that executes an operation in accordance with a safety program, a setting module that receives an evaluation condition, a first determination module that changes the value of the input signal to be evaluated, from a first input value which is an initial value to a second input value, and determines whether a first output value of the output signal to be evaluated which is determined by the process execution module is identical to the expected output value, a second determination module that restores the value of the input signal to be evaluated, from the second input value to the first input value, and determines whether a second output value of the output signal to be evaluated which is determined by the process execution module is identical to the first output value, and an output module that outputs a determination result.

Abstract: An evaluation system includes: processing execution means for executing computation in accordance with a safety program; setting means for receiving an input signal of an evaluation target and an expected output value; first determination means for determining whether or not a first output value of an output signal decided by the processing execution means coincides with the expected output value based on reception of a change in the value of the input signal from a first input value to a second input value from an input device; second determination means for determining whether or not a second output value of an output signal decided by the processing execution means coincides with the first output value based on reception of returning of the value of the input signal from the second input value to the first input value from the input device; and output means for outputting determination results.
