Title:
SEQUENCE TABLE TYPE CONTROLLER
Document Type and Number:
Japanese Patent JPS63293604
Kind Code:
A
Abstract:
PURPOSE:To improve the productivity and the quality of a program with a sequence table type controller by having the output of the state of a device designated as an interlock and the AND arithmetic result as the operation output signals. CONSTITUTION:The interlock conditions C are given to an output signal name and a process number B. In this example, the ON signal of an FIC103 and the OFF signal of a DI12 are applied to an output signal TIC101 and PL1 as the interlock signals respectively. Therefore the signal TIC101 is outputted only when the ON signal of the FIC103 exists; while the signal PL1 is outputted only when the OFF signal of the DI12 exists. Thus it is possible to obtain simple a sequence control function without deteriorating the program productivity and quality just by setting an equipment number and its state related to an interlock function.
