Abstract

PURPOSE:To simplify a multiple block controller of a system having a number sets of blocks with the same control pattern or content in a facility by commonly using the same logic of the leased block control circuits. CONSTITUTION:In a multiple block controller seen in a waste treating system as an example having one process of several groups each having several same treating contents as one group, a block selection switch 25 is assembled in a graphic panel for displaying the system flow and operating state in such a manner that the same logic of leased block control circuits 28 is commonly used and signal communication among the processes is conducted between the common control circuits 27. Reference numerals 19 to 21 designate A1 to A3 leased block logics, 22 to 24 A1 to A3 block body devices, and 26 a block selecting circuit.
