1. A debugging assistance device for assisting in debugging of a program executable by a programmable logic controller, the debugging assistance device comprising:
first processing circuitry to
collect, from the programmable logic controller, input-output data representing a log for a device in a program predetermined as a logging target program of one or more programs executable by the programmable logic controller, and
generate, when a debugging target program is determined not to be included in the predetermined program, input-output data representing a log for a device in the debugging target program by executing a simulation program simulating an operation of the programmable logic controller.
