PURPOSE:To cancel the troublesome preprocessing of a performance test, and to improve testing efficiency by providing a data switching part to replace data on a data bus with the set data in a data setting part when a set address by an address setting part corresponds to the address on an address bus. CONSTITUTION:The data such as a digital input (DI), a digital output (AI), an analog output (AO) to be treated in an information processor all appear on the data bus of the common bus. Consequently, the address on an address bus 600 is always supervised, the fact that the address has corresponded to the set address is detected by an address correspondence detecting circuit 302, the data on a data bus 700 are replaced with the set data by means of the switching of a contact point by a data switching part 304, and the pseudo input of the set data to an MPU is executed. From this, without any preprocessing, the pseudo input is executed at the normal operation timing of the information processor. |
