<p>PURPOSE:To easily identify the states of plural internal events by one output, by adding different weight one the element of each event. CONSTITUTION:The formation, or the failure of the state of each of the events A-D that are the elements of the internal event 10 of a programmable controller, is corresponded to a level signal of '1', or '0', and it is inputted to weight multipliers 20a-20d of an arithmetic circuit 20 as state output signals 16a-16d, respectively. Weight output signals 18a-18d of 2<0>, 2<1>, 2<2>, and 2<3>, are inputted from a weight output apparatus 14 respectively to the weight multipliers 20a-20d, then they are multiplied by the state output signals 16a-16d. All of the output signals on which multiplication are performed at each of the multipliers 20a-20d are added by adders 22d, 22b, and 22c, and they are outputted as one continuous quantity S from an adder 22a.</p> |
