1. there is a magnetic starter for network savvy, including magnetic starter main body and control circuit, it is characterized in that:

  • in controlArranging a Communication processing module in the control loop of circuit processed, the hardware of Communication processing module sets with single-chip microcomputer for coreMeter;

    Communication processing module one toggle switch of design, for arranging the slave station of the MODBUS RTU communications protocol of magnetic starterAddress;

    Communication processing module designs one and selects switch, for arranging the control model of magnetic starter, optional control modelHaving two kinds, respectively, by connecting manual signal cable adapted and starting, stop button switch carries out local control, Yi JitongCross MODBUS net, MODBUS rtu protocol main website remotely control;

    Communication processing module is designed with some inputs, output connectsPoint, these contacts carry out distribution with the control loop of magnetic starter and are connected, to realize carrying out the catalyst of magnetic starterThe control being switched on or switched off, it addition, these contacts use Phototube Coupling unit, to increase the capacity of resisting disturbance of modular circuit and defeatedEnter the Stability and dependability of output signal;

    By the single-chip microcomputer of Communication processing module being carried out software programming, design oneMODBUS RTU Communication processing functional device, for realizing and other master device of MODBUS net, assists with MODBUS RTU communicationView carries out combined network communication and data exchange;

    By the single-chip microcomputer of Communication processing module being carried out software programming, design dataCaching process functional device, this functional device receives through MODBUS RTU Communication processing functional device for caching process, and fromOther master device of MODBUS net send the control command starting or stoping magnetic starter of coming;

    By to communicationThe single-chip microcomputer of processing module carries out software programming, designs a motor on off control functional device, and this functional device is in control modelWhen being chosen as network control, according to control command and the letter of Dynamic Contact device auxiliary contact of the storage of data buffer storage function blocksNumber state, service meter on off control logic, complete the on off control to motor.
