ModBus network is an industrial communication systems, by band intelligent terminal programmable controllerbe formed by connecting by public line or local dedicated line with computing machine.Its system architectureboth comprise hardware, also comprise software.It can be applicable to various data acquisition and process monitoring.ModBus network only has a main frame, and all communication is all sent by him.Network can support the remote slave controller of 247 more than, but will being determined by communication facilities used from machine number of supporting of reality.Adopt this system, each PC can exchange information with central host and not affect the control task of each PC execution itself, Modbus protocol open, standard, and user can freely use relievedly.Modbus supports multiple electrical apparatus interface.The frame format of Modbus agreement is simple, compact, easy-to-understand.User uses easily, and manufacturer's exploitation is simple.

utility model content:

It is simple that the utility model object provides a kind of structural principle, can simplified apparatus manufacture difficulty and save the technical scheme of considerable cost:

A kind of driven by servomotor proving installation, mainly comprise the first servo-driver, second servo-driver, first motor, second motor and a Modbus module, 2nd Modbus module, first servo-driver and the second servo-driver structure completely the same, first servo-driver, the L1 end of the second servo-driver connects power supply L phase, L3 end connects power supply N phase, L1C end connects L1 end, L2C end connects L3 end, and the first servo-driver, the U end of the second servo-driver, V holds, W end connects the first motor respectively, second motor, one Modbus module, 2nd Modbus modular structure is completely the same, and input end respectively with the first servo-driver, second servo-driver is connected, output terminal connects PC.

As preferably, Modbus module comprises microcontroller, ethernet PHY chip, Ethernet interface, RS485 transceiver, RS485 communication interface, USART communication interface, the output signal that output signal and the ethernet PHY chip digital input signal of microcontroller are connected ethernet PHY chip is connected to Ethernet interface, TXD1 and RXD1 of microcontroller is connected to RS485 transceiver, the positive and negative signal end of RS485 transceiver is connected to RS485 communication interface, TXD2 and RXD2 of microcontroller is connected to USART communication interface.

As preferably, microcontroller model adopts LPC1758, and ethernet PHY chip model adopts RTL8139C.

The beneficial effects of the utility model are:

The utility model improves on traditional basis, traditional servo-driver is increased Modbus module, make the servo-driver being with Modbus agreement into, delete the logic controller in conventional art simultaneously, this makes originally to seem that valuable space saved out by close-packed panel box, eliminates the cumbersome process of many distributions simultaneously, makes system become structure simple, make easily, saved considerable cost.
