Abstract

The invention relates to the technical field of programming cables, in particular to a multi-purpose PLC (programmable logic controller) programming cable which comprises a connecting module, wherein one end of the connecting module is connected with a COM (component object model) port of a PC (personal computer) end, the other end of the connecting module is connected with a programming port of the PLC, and the multi-purpose PLC programming cable is characterized in that the programming port of the PLC comprises three interfaces, the three interfaces are an 8-pin raw interface, a 9-pin D-shaped interface and an RJ11 (registered jack 11) interface respectively, a functional switch for selecting one of the three interfaces to connect with the connecting module is arranged on the connecting module, and the COM port of the PC end is an RS232C (recommended standard 232C) interface of a DB-9-pin plug. Due to the adoption of three interface forms, the different interfaces can be selected according to different using conditions, thereby bringing convenience to learning and using.

Description

technical field [0001] The invention relates to the technical field of programming cables, in particular to a multipurpose PLC programming cable. Background technique [0002] With the widespread application of programmable logic controllers in the field of industrial control, PLC programming has become a professional skill that electrical engineering technicians must master. However, because the programming cables of different brands of PLCs cannot be used universally, the original programming cables are expensive, which brings inconvenience to learning and using PLCs. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a multi-purpose PLC programming cable which is convenient to use. [0004] The technical solution adopted by the present invention to solve its technical problems is: a multipurpose PLC programming cable, which has a connecting module, one end of the co...
