Claims9
A control device of a first classification in a communication control system including the control device of the first classification and one or more control devices of a second classification connected to the same bus as the control device of the first classification, the control device comprising:
- a transmission and reception unit that transmits or receives a signal via the bus by a half-duplex communication method;
- and
- a control unit that prohibits driving of the transmission and reception unit when an occurrence of an abnormality in an own device is detected.
A communication control method for a communication control system including a control device of a first classification and one or more control devices of a second classification connected to the same bus as the control device of the first classification, the communication control method comprising:
- transmitting or receiving a signal via the bus by a half-duplex communication method by the control device of the first classification;
- and
- prohibiting driving of a transmission and reception unit included in the control device of the first classification by the control device of the first classification when an occurrence of an abnormality in an own device is detected.
A non-transitory storage medium storing a communication control program that causes a processor provided in a control device of a first classification in a communication control system including the control device of the first classification and one or more control devices of a second classification connected to the same bus as the control device of the first classification to function as:
- a transmission and reception unit that transmits or receives a signal via the bus by a half-duplex communication method;
- and
- a control unit that prohibits driving of the transmission and reception unit when an occurrence of an abnormality in an own device is detected.
