PURPOSE:To simplify the constitution of a data controlling circuit by incorporating a communication control device to one set, providing a priority degree selecting circuit, and transmitting a data in order of the priority degree. CONSTITUTION:Transmission of a data is program-controlled by a microcomputer of a controlling circuit of the data, and the data whose priority degree is determined is stored in each address position in a priority degree distinction data memory 9. Contents of a priority degree distinction register 9-1 of this memory 9 are read out to a priority degree selecting circuit 7 in order of the priority degree, and are provided as a logic 1 to one input of corresponding AND gates 4-1-4-4. Also, the data of the address position of the register 9-1, which is read out to the circuit 7 is read out to a communication controlling circuit 6 from an information memory 9-2, and the data read out to the circuit 6 is provided in parallel to the other input of the gates 4-1-4-4. In this state, the data is transmitted from the gates 4-1-4-4 in order of the priority, and the constitution of a data controlling circuit is simplified. |
