JPS5624602A - Control processing device - Google Patents

Abstract

PURPOSE: To fetch the input successively from the selecting circuit and simplify the construction of the device by providing a pripority selecting circuit at a previous stage of the input of the control processing device and making invalid the treatment of another table as the previous treatment priority when a plurality of control tables select the same control object.

CONSTITUTION: The control processing device A is composed of a priority selecting circuit B, an input circuit C, a code circuit D, a synthesizing circuit E and an output circuit F. To this selecting circuit B, push button signals 1PWnP from a plurality of the control tables 1TWnT are supplied. In this selecting circuit B, the relays for storing respectively the signals 1PWnP and a previous treatment discriminating circuit of the respective relays through the series connected recovery contacts except for self-retaining of the respective relays are provided. Through the self-retaining circuit of the action of the respective relays through the self-operating contact and the operating contact of the respective relays except for itself which are connected in parallel, in the control tables 1TWnT, the alarm forming circuit for feeding back the respective alarm signals 1aWna is disposed. Then, the treatment of another table as the previous treatment priority is informed through alarm, and the input is successively selected from the selecting circuit B to be fed to the input circuit C.
