Abstract

This invention provides a program compiling system and method for programmable logic controller (PLC), which contains the user compiling program by selecting menu mode in menu operation interface, avoiding logic program error by the mutually exclusive setting of menu selection to obtain easy learning, right and reliable compiling.

Description

technical field [0001] The invention relates to a program editing system and method, in particular to a program editing system and method of a programmable logic controller with a menu operation interface. Background technique [0002] With the advent of the era of industrial automation, the programmable logic controller plays the role of central control. Users can edit the program instructions into the storage module of the programmable logic controller, so that the programmable logic controller can generate corresponding control logic (control logic ) to control output devices (for example, relays or lights, etc.). [0003] Generally speaking, in order to plan some special application commands (for example, high-speed counting, etc.), it is necessary to set some related output, initial value of input switch and matching system parameters, and even interrupt settings, etc., unless used Readers are very familiar with program-related instructions. Otherwise, they need to rel...
