Abstract

The invention discloses a method for operating a PLC system, which comprises the following steps that firstly, whether a cutter controlled by a servo motor is in an initial zero position state or not is detected, if not, the servo motoris controlled to return to zero, if so, starting to enter the step is conducted, and then the rubber cushion cutter is driven by the servo motor to rapidly feed to a set position according to a set speed, and the position of the PLC system is set in front of a contact point; a logic control area is divided in a frequency converter processor, and a PLC program analysis module is arranged in the logic control area; the PLC program analysis module is used for loading a PLC file, and the PLC file is obtained by performing development processing in a PLC upper computer; the PLC program analysis module detects a triggering condition for executing the PLC file; and when the triggering condition is met. The method for operating the PLC system is accurate in adjustment, high in precision and wide in use value.

Description

technical field [0001] The invention relates to the technical field of PLC control, in particular to a method for operating a PLC system. Background technique [0002] The PLC system is called a programmable logic controller, which is a digital operation electronic system specially designed for application in industrial environments. It uses a programmable memory to store instructions for performing logic operations, sequence control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production through digital or analog input and output. process [0003] At present, the accuracy of operating the PLC system is not high, and the operation method is relatively complicated. Therefore, we propose a method for operating the PLC system. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the present invention provides the following technical solutions: a method for operating a PLC system, the operating...
