Editing self-adaptive display method for ladder diagram programming

Abstract

The invention discloses an editing self-adaptive display method for ladder diagram programming, which comprises the following steps: firstly, generating and displaying a ladder diagram editing interface, and then editing and displaying a ladder diagram in the ladder diagram editing interface in response to user operation. In the editing process, if a functional block exists in the ladder diagram, branches connected with pins of the functional block are obtained and monitored, and when it is monitored that the branches connected with the pins of the functional block change, whether spacing adjustment needs to be carried out or not is determined according to the change; and if the adjustment is needed, adjusting the distance between the pins of the functional blocks and the distance between the branches connected with the pins in the vertical direction of the ladder diagram editing interface according to the change and a preset distance adjustment rule. Since the branch spacing and the spacing of the connecting pins corresponding to the functional blocks can be dynamically adjusted according to the change of the connecting branches of the functional blocks, when the functional blocks of the ladder diagram are displayed, the connecting relationship is more concise, more attractive and more practical, the display mode of the ladder diagram is optimized, and the editing efficiency of the ladder diagram is improved.
