A communication device (10) is provided with: a parallel interface (11) that communicates with a placing port (20); a network communication unit (14) that communicates with the transport carriage (30) via a network; and a control unit (13) that controls the parallel interface (11) and the network communication unit (14). In an interlock sequence for transferring, between the placing port (20) and the transport carriage (30), a subject to be transported, the control unit (13) takes a predetermined standby period before transmitting a packet to the transport carriage (30) after having a signal inputted from the placing port (20), and the predetermined standby period is changed corresponding to whether there is an error.
