1. A control system, comprising:
a PLC system including an input unit configured to obtain actual sampling data storing a first sampling value and a first sampling timing that are associated with each other, the first sampling value being obtained by sampling an input signal at a first timing, the first sampling timing being a timing at which the input signal is sampled, an output unit configured to output an output signal based on output instruction data including a designated output timing and a designated output signal value, the designated output signal value being an output signal value to be output at the designated output timing, and a controller including a task execution unit and a sampling unit, the task execution unit being configured to repeatedly execute a task in a predetermined period, the task including I/O refresh processing for updating a value of an input variable associated with the input signal based on the input signal and updating the output signal based on an output variable associated with the output signal, and processing for executing a user program including calculating a value of the output variable by executing the user program based on the input variable, calculating the designated output timing and the designated output signal value based on the value of the output variable to generate the output instruction data, and transmitting the output instruction data to the output unit, the sampling unit being configured to obtain variable sampling data storing a second sampling value and a second sampling timing that are associated with each other, the second sampling value being obtained by sampling the input variable, the output variable, and/or an internal variable used in the user program at a second timing, the second sampling timing being a timing at which the input variable, the output variable, and/or the internal variable is sampled; and a development support apparatus including a same time-series data generation unit configured to generate same time-series data storing the first sampling timing, the second sampling timing, and the designated output timing arranged in the same time series, the first sampling value, the second sampling value, and the designated output signal value being associated with timings in the same time series corresponding to the first sampling timing, the second sampling timing, and the designated output timing, and a same time-series data display unit configured to display the same time-series data on the same time axis. |
