The realization method of plc interactive fc function

Abstract

The present invention provides a method for realizing PLC interactive FC function functions. PLC drives the driver through driving instructions. PLC includes FC function sub-modules, and FC function sub-modules include FC function functions. FC function functions include: jog / inch control strategy, Single-action control strategy, speed / torque / displacement control strategy, fault acquisition and fault reset strategy, actual parameter reading and writing and dynamic parameter writing strategy, among which, the FC function uses time-sharing trigger MASTER or extended frame + data frame interactive command, Secondary retransmission mechanism. This method can solve the problem of unification of interaction between different PLCs and different drivers, improves the interaction efficiency and flexible setting of network nodes, and greatly reduces the uncertainty risk caused by procurement. It adopts parameter input and output methods, and FC function function It adopts black box encapsulation and encryption, flexible and convenient program reference, and can realize various complex control functions.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for realizing a PLC (Programmable Logic Controller, Programmable Logic Controller) interactive FC (function), a non-transitory computer-readable storage medium and a computer device. Background technique [0002] At present, PLCs have FC sub-function modules that are interactively associated with their own brand drivers, which respectively implement sub-functions such as start-stop control, pause, return (return to zero), absolute displacement control, relative displacement control, and read and write. Can be called multiple times independently. [0003] However, when the PLC interacts with similar drivers of other brands, it is impossible to achieve repeated calls. It is necessary to develop an innovative FC sub-function module, add the Pulse / mm conversion function separately, and require a physical detection switch to return to zero, and it is difficult ...
