Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
A kind of real-time ethernet EtherCAT main station system, its composition frame chart as shown in Figure 1, comprising: microprocessor, master station module, ethernet controller, program storage, data storage; Described microprocessor is connected with data storage with master station module, ethernet controller, program storage by data wire.
Microprocessor realizes EtherCAT main website and controls to call, and comprises main website and host computer network configuration software communication, completes by host computer network configuration software instruction functions such as the initialization of EtherCAT master station module, network configurations.Microprocessor adopts domestic SPARCV832 bit CPU, and dominant frequency can reach 100MH
z, it extends out data wire can 32 and 16 bit patterns, and its memory space and IO space can independently be arranged, and therefore plate level memory all adopts 32 bit patterns.
Master station module provides dual port RAM, realizes the master station protocol communication function of described EtherCAT main station system.Master station module adopts German He You to interrogate Industrial Ethernet module COMX100CN-RE.COMX100CN-RE module is connected with microprocessor SPARCV8, realizes EtherCAT master function.The winding diagram of COMX100CN-RE module and SPARCV8 as shown in Figure 2.COMX100CN-RE module provides host device interface to be DPM (DualPortMemery, dual port RAM), is realized the application programming interfaces of EtherCAT main website related communication by DPM.Master station module is concerning coupled microprocessor, and on hardware, suitable one extends out RAM.In addition, COMX100CN-RE module also provides a diagnose interface DiagnosticInterface to be used for carrying out firmware downloads between agreement (having corresponding WINDOWS software) and diagnosis of dispatching from the factory.DiagnosticInterface hardware provides UART, USB two kinds of interfaces.The present embodiment adopts UART mode, and can realize RS232 mode and communicate by mistake 1 road RS232 transceiver.Microprocessor and COMX100CN-RE module are articulated in the IO district of microprocessor by DPM mouth, adopt 16 bit patterns, microprocessor is large end pattern U, when it connects small end peripheral hardware COMX, data wire height eight is exchanged connection by hardware, and its sheet elects IOCS IO sheet choosing after expansion as.Because COMX read-write sequence requires to utilize the BRDYN signal of Low level effective, and microprocessor SPARCV8 peripheral hardware IOBUSY signal to be high level effective, the two needs to realize logic coupling by a not gate.
Ethernet controller adopts 2 ethernet control chip MAC0 and MAC1, for providing the communication interface with host computer, to realize the relevant communication configuration management of EtherCAT main website.
Program storage controls to call and host computer communication function code for storing main website, and storage networking configuration data (XML file), for master station module; Data storage controls the data of caller and the operation of host computer communication function program for storing main website.Program memory ROM adopts FLASH; Data storage RAM adopts SDRAM.For making ROM maximize, adopt 32 bit wides be spliced into by two groups of 2 16 bit wide FLASH to extend out ROMSN0 and ROMSN1 two ROM address spaces that ROM is connected respectively to microprocessor.32 SDRAM supported by microprocessor, therefore, extend out RAM and are also designed to be spliced into 32 SDARM by two panels 16 SDRAM.
The present embodiment needs expansion to have 3 peripheral hardwares: two ethernet controller MAC0 and MAC1, a COMX.Microprocessor selected by the present embodiment only has 1 road IO chip selection signal IOSN, therefore needs expansion IO chip selection signal to realize the function of management 3 IO peripheral hardwares.Utilize A24, A25 two address wires of CPU to control the IOSN signal of 2-4 decoder gating microprocessors, realize 4 sheet choosing expansions, MAC0 and MAC1 is distributed in the choosing of the first two expansion IO sheet, and COMX is distributed in the choosing of the 3rd expansion IO sheet.
The utility model is not limited to above-mentioned execution mode, those skilled in the art make to any apparent improvement of above-mentioned execution mode or change, all can not exceed the protection range of design of the present utility model and claims.
