PURPOSE:To detect erroneous constitution of logic packages by selecting information to be controlled from many logic packages through a switch part by a control part and transmitting selected information to a main processor and comparing it with preliminarily set function information. CONSTITUTION:A function block 6 is constituted with a control part 5 consisting of a control circuit 2 and a selecting part 3 and many logic packages 4, and each package 4 is provided with a switch part 10, and the circuit 2 is connected to a main processor. The circuit 2 controls the selecting part 3 when receiving a device state information gathering instruction from the processor 1, and the selecting part 3 receives a function level signal from the package 4 as information to be controlled through the switch part 10 and is compared with a function level which is received through the circuit 2 and is set preliminarily, thus detecting erroneous constitution of the package 4. |
