| 摘要 | PURPOSE: To reduce the number of manpower for the test as well as to perform the test from the remote place in a simple way by applying such contrivance to the circuit constitution that the fixed input/output device of the process controller is used for the input/output purpose of the test data. CONSTITUTION: Devices AI1WAI16 of block A at input part 3B of process controller 3 are used for the input/output purpose of the test data; while devices AO1W A016 of block A at output part 3C are used for the decision result output for the test respectively. The test contents results in a certain decision in case the signal of limit switch 1 at point A is supplied to device B15 of block B at part 3B. In this case, the signal is delivered from device E09 of block E at part 3C. And in the case of the contents which makes lamp 4 glow at point B, the data designating B15 is first set to digital switch 61 of operator console 6 and then selection switch 62 is switched toward the input test. And push-button switch 63 is pushed to supply the set data to input controller 56. COPYRIGHT: (C)1979,JPO&Japio |
