PURPOSE:To dispense with a troublesome connection/disconnection work or an independent unit, and to drastically reduce the cost of a simulation work by providing a simulation function within a control device itself, and performing internally the simulation of a digital input output. CONSTITUTION:Both the states of an actual input and a simulation input are stored in a virtual input storing means E, and the input to be processed is supplied to a process controlling part D from the means E, and further, the state of the simulation input is displayed at a displaying means K by a setting/ displaying means L. On the other hand, an output from the control part D, which is the processed result of the actual input and the simulation input, is stored din a virtual output storing means F, and the contents of the means F, excluding a matter related to the simulation, is stored in an actual output storing means C, and is outputted to a process A, and at the same time, the output state, corresponding to the simulation input, is displayed at the means K by the setting displaying means M. Accordingly, the simulation of the digital input output comes possible without a signal input from an external part and a signal output to the external part. |
