The control device 203 receives the control packet at the controller-side network input / output unit 104 and performs error processing at the controller control unit 102.

Also, when a reservation is made by operating the device to be controlled 201 itself, the reservation management information is stored in the controlled reservation management information storage means 109 in the second format data.

In this case as well, the controlled reservation management information storage means 109 manages the reservation time as described above, and can resolve inconsistencies such as overlapping reservation times and guarantee the reservation execution operation. Can be.

As described above, both the first format data and the second format data can be centrally managed by the controlled reservation management information storage means 109 in the second format data, and the reservation execution operation can be performed. Can be guaranteed. Further, when the reservation management information to be registered is duplicated, it is possible to determine which reservation management information is to be deleted according to the user's request, and to reliably execute the reservation desired by the user. Is possible. Further, the control device 203 of the present embodiment does not need to have a storage unit for the reservation management information, so that the load on the control device can be reduced.

As the first data format and the second data format, data formats other than those shown in FIGS. 5 and 6 may be used. When converting the first data format to the second data format, if there is no corresponding data item or cannot be obtained by data conversion,
Alternatively, when there is an item for which data cannot be obtained by calculation from a plurality of data, the data may be left empty, or a dummy data having no meaning may be inserted.
