Abstract
A cable length calculation system () includes a controller () and a plurality of communication apparatuses () which are connected via a cable (). A measurement master which is one communication apparatus () among the plurality of communication apparatuses () counts as a first number, the number of clock signals output by an oscillator from a time of transmitting a measurement packet until a time of receiving a response packet. A measurement slave which is a communication apparatus () different from the measurement master among the plurality of communication apparatuses () counts as a second number, the number of clock signals output by an oscillator from a time of receiving the measurement packet transmitted by the measurement master until a time of transmitting the response packet. The controller () calculates a length of the cable () between the measurement master and the measurement slave based on the first number and the second number.
