PLC METHOD FOR PREVENTING INTERFERENCE BETWEEN PLC PROGRAM BLOCKS

摘要

The present invention relates to a method for preventing collision and interference due to dependencies between PLC devices, and by automatically checking dependencies in the process of program block input by a dependency parameter set in advance between devices and program blocks, when operating a PLC system. This has the effect of preventing the PLC system from malfunctioning or being damaged due to device-to-device interference not intended by the user.
