<p><P>PROBLEM TO BE SOLVED: To perform transmission of a switch signal, i.e., a monitoring signal and an analog signal between first and second control circuit parts where monitoring and control signal are serial-communicated while reducing burden of communication. <P>SOLUTION: The first control circuit part 200a performs input/output control in cooperation with a micro-processor 110a, a program memory 115a and RAM memory 116a. The second control circuit part 200b performs serial communication with the first control circuit part 200a in cooperation with a communication control circuit part 120a and a data memory 126a. A switch signal input inputted to the second control circuit part 200b is stored in a first report packet and a digital conversion value of analog signal input is stored in a second report packet. They are alternately periodically transmitted to the first control circuit part 200a. A multi-channel AD converter included in the analog signal input circuit 123b transmits the newest AD conversion data by starting AD conversion after a predetermined time after transmitting the first report packet and completing the conversion until the second report packet is transmitted. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
