Embodiment Construction

[0026] Such as figure 1 As shown, in the embodiment of the present invention, a port conversion method of PLC configuration software is provided, which includes steps S1-S3. Each will be described below.

[0027] Step S1: Establish a mapping relationship table between logical ports used by the PLC configuration software and physical ports of the PLC hardware device.

[0028] When it needs to be explained, in the embodiment of the present invention, in order to realize the decoupling of the application program and the specific PLC hardware, the input and output ports of the PLC hardware device are abstracted into logical ports, the application code uses the logical ports, and the PLC configuration software uses The mapping relationship table between the logical port and the physical port of the PLC hardware device, when it needs to be output to the target PLC hardware, maps the logical port to the PLC physical port, so as to realize the binding of the logical port and the phys...

Abstract

The invention discloses a port conversion method and system for PLC configuration software. The method comprises the steps: establishing a mapping relation table between logic ports used by the PLC configuration software and physical ports of PLC hardware equipment; and compiling the PLC configuration software, and converting a logic port used by the PLC configuration software into a physical portof the PLC hardware equipment by adopting the mapping relation table. By the adoption of the technical scheme, decoupling of the configuration software application program and specific PLC hardware can be achieved under the condition that a middle layer is not adopted.

Description

technical field [0001] The invention relates to the field of PLC configuration software, in particular to a port conversion method and system of PLC configuration software. Background technique [0002] The application program written by the PLC configuration software reads the input from the input port (Input) of the controlled hardware motherboard, performs logic processing, and then sends the output to the output port (Output). [0003] The IO port can be abstracted into a logical port, and the application code uses the logical port to realize the decoupling of the application program and the specific PLC hardware. When it is necessary to output to the target PLC hardware, the logical port is mapped to the PLC physical port, so as to realize the binding of the logical port and the physical port. [0004] There is no concept of logical ports in the current PLC configuration software, only physical ports. Always use the specified physical port of the PLC in the applicatio...
