PROBLEM TO BE SOLVED: To provide a device for monitoring a RAM value capable of monitoring a microcomputer RAM value in real time even without improving the performance of a computer for operation to be connected. SOLUTION: A device 10 connected to a personal computer(PC) for operation and to a microcomputer 2 that should monitor a RAM value (data value in RAM) and for acquiring the RAM value of an address instructed from the PC from the microcomputer 2 to output the RAM value, is provided with a setting part 13a that can store a plurality of read object addresses of a RAM value, circuits 13b, 7 and 9 which sequentially acquire the RAM value of each read object address stored in the setting part 13a and also repeat operation that performs D/A conversion of the each RAM value to output the each RAM value subjected to D/A conversion to an external measuring instrument, and a microcomputer 11 for control. The microcomputer 11 stores read object addresses transmitted from the PC in the setting part 13a according to an instruction from the PC and also outputs a scanning start request to the circuits. |
