<p><P>PROBLEM TO BE SOLVED: To examine correspondence on a host system side, in advance, by storing a previously assumed output trend in a storage device in a special output state unique to field equipment, and outputting the stored output trend through simulation, when an output simulating function is implemented. <P>SOLUTION: The field apparatus includes the storage device configured to store the previously assumed output trend in addition to an abnormal value stored in a simulation part, and a random number generation device, and selects the abnormal value stored in the simulation part, the output trend stored in the storage device, and simulation data generated by the random number generation device and outputs them to a diagnostic processing part. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
