PROBLEM TO BE SOLVED: To provide a data communication method, with which wait is enabled for plural modes for allowing switching of the receiving mode of a high-order radio part either to the public mode of PHS or to transceiver mode corresponding to the communication connection destination to connect communication with a repeater station by preparing two radio parts of the high-order radio part and a low-order radio part. SOLUTION: Concerning the data communication method for periodically transmitting data generated in a low-order terminal to a high-order device, communication with the low-order terminal, which temporarily occurs, is performed by using the transceiver function of PHS so that maintenance work from a remote position can be facilitated. |
