PERFORMANCE TEST SYSTEM FOR CONTROL DEVICE

PURPOSE:To miniaturize a control device and to attain the decrease in the cost of the device by setting the operation or non-operation state of a special circuit element as one of operation parameters, outputting a forced operation signal or a forced non-operation signal from the circuit element and simulating the operation or non-operation of the circuit element. CONSTITUTION:The operation or non-operation state of a special circuit element or a function in the internal part of the control device is handled as one of operation parameters and inputted by a setting mechanism 1. For example, in order to simulate that a circuit element A is operated, the operation conditions of the circuit A assigned to the setting mechanism 1 are set, by which, the forced action signal is inputted to one side input terminal of an OR circuit OR1 through a decoder 2 by which the same state as that of operat ing the circuit element A is generated. In such a way, since an performance test exclusive-use forced operation terminal, a forced non-operation terminal, further, an input output signal terminal and the interface circuit of these signals are made unnecessary, the control device can be miniaturized and made into the low cost.
