Abstract
A first control circuit portion carries out input/output control in cooperation with a microprocessor, a program memory, and a RAM memory. A second control circuit portion is in cooperation with the communication control circuit portion and the data memory to carry out serial communication with the first control circuit portion. A switch signal input to the second control circuit portion is stored in a first report packet, a digital conversion value for an analog signal input is stored in a second report packet, and the first and second packets are alternately periodically transmitted to the first control circuit portion. A multi-channel AD converter included in an analog signal input circuit starts to carry out AD conversion a prescribed time period after a first report packet is transmitted and finishes conversion before a second report packet is transmitted, so that up-to-date AD conversion data is transmitted.
