PURPOSE:To gather data in a high-speed scanning cycle by using an input device which can input data directly to a buffer where several scan data can be stored and changing the wire address of the buffer in the input device, an interrupt generation table, and a timer before data gathering is started when test conditions are satisfied. CONSTITUTION:An interrupt generation address for gathering is calculated in accordance with the scanning cycle for gathering which is set while a monitor means 4 is operated before gathering of test data, and this address is set to a table 20 to prepare for test. When test conditions are satisfied, a buffer initializing means 21 refers to the interrupt generation table 20 for gathering to change a write address 15 to the start address of a buffer following a current input buffer, and an interrupt generation table changing means 22 started by the buffer initializing means 21 changes contents of an interrupt generation table 16 indicating the address where a input device 2 generates an interrupt, and the input of data due to the scanning cycle for gathering is started, and data is gathered when the interrupt of one buffer full is generated. |
