摘要： A load control device includes a device that has a plurality of operation modes depending on applications and is electrically connected to a load. The device includes an operation mode determination circuit. The operation mode determination circuit is configured to: set a tentative operation mode indicating the operation mode before determination; obtain operation mode information regarding the operation mode via communication, the operation mode information including an error detection code for detecting an error of the tentative operation mode; determine whether or not a setting result of the tentative operation mode is correct using the error detection code; and determine the operation mode of the device based on a determination result.

摘要： A CGW (7) connected to a first communication network (1) and a fifth communication network (5). The second communication network uses a communication protocol different from a communication protocol of the first communication network (1). The CGW (7) receives, from the first communication network (1), CAN frames each including a data field storing control information (CD) to be transmitted from the first communication network (1) to a second communication network (5), a CAN ID for identifying the control information (CD), and an error detection code (EC) stored in the data field and calculated on the basis of the control information (CD) and the CAN ID. The CGW (7) generates an FD frame including a data field storing the CAN frames and a CAN FD ID indicating that the CAN frames are stored in the data field, and transmits the generated FD frame to the fifth communication network (5).

摘要： A relay device includes a relay connected between a first communication network and a second communication network. The second communication network uses a communication protocol different from the first communication network. A first frame is transmitted in the first communication network, and has a first payload including control information, a first data ID for identifying the control information, and a data length code indicating a data length of the first payload. A second frame is transmitted in the second communication network, and has the first frame, a second data ID indicating that the first frame is included, and unique data stored in a predetermined storage area at a position behind the first frame. The relay recognizes the first frame without performing a frame recognition process on the data in the predetermined storage area when recognizing the first frame in the second frame on a basis of the data length code.
