The younger brother (Bu 1) network control, in the embodiment of the present invention, the network controller of the above-mentioned first-period is connected by a series controller, and the domain material is connected with money; a part, and the grounding controller of the door causing electromagnetic interference transmits the own identification code and the network (4) sequentially by transmitting the network operation command in the operation command to each network controller. At present, the mother is identified, and the relevant operation is performed by checking the order of 4:=, and then the current=execution operation finger is sequentially passed through each network to determine whether it is from the specified network_ Network controllers do not need to be given special sections. So - reduce the complexity of the design. The job code will be able to make the above characteristics and advantages of the thorns more touching. (4) Only the example is given. The sub-combination with the drawings is described in detail below. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is a spear of a network device of the present invention. Referring to FIG. 2, the network device includes a processor 21A and a network 220J 220 220_N, where N is a positive integer. The controller processor 210 is configured to provide an operation command to identify the stone horse so as to control the network controller 22 to operate. The network control states 220-1 to 220-N each have a first interface and a second interface and a device identifier, and the first interface of the i-th network controller 220" is coupled to the processor 210. The second interface of the first network controller 22〇j is coupled to the first interface of the peripheral control state 220-2, and the second interface of the second network controller 220-2 is coupled to the third network. The first interface of the third network controller 220-3 is coupled to the first interface of the fourth network controller 220-4, ..., the N-1th network The second interface of the path controller 220-N-1 is coupled to the first interface of the Nth network controller 22〇_N. The network controllers 220J~22〇_N will sequentially receive the above operation instructions: and determine whether to execute the operation instructions to perform related operations according to the check device identification code and the current identification code. For example, it is assumed that the device identification codes of the network controller 22〇1~220-N are all set to, and the first preset value and the second preset value are respectively set to 1. In addition, the identification code in the operation command is assumed to be "2" to transmit the operation instruction to the corresponding network controller for subsequent operations. First, when the network controller 220-1 receives the operation command provided by the processor 210, it checks the device identification code and the current identification code. Since the device identification code of the i-th road controller 220_1 is "〇" and the current identification code is "2", the 网路th network controller 22〇 checks that the device identification code is different from the current identification code. . "At this time, the first network controller 220J will subtract the first preset value "丨" (that is, 2_1=1) from the identification code '2'' of the operation command, and the operation will be deducted by the brother 1 The second interface of the network controller 220-1 is transmitted to the first interface of the second network controller 220_2. Ο 〇201101762 jn〇6iwi.doc/n When the second network controller 22GJ receives the check: The code and the current identification code. Because the second network control: two =, the identification code is "〇" ' and the current identification code has been updated to the first - target identification code Ϊ, so the second network control cry 220 2 people; & no-day code is not the same as the target ID. 〇—2 Detecting the device to know the monument' Ί Then / Λ 2 network controllers 220-2 will recognize the operation command 220, the second and eighth, ΐ 作 指令 command through the second network controller interface 2; The first when the third network controller 220 is sent to the third network controller 220, when the operation command is received, the device identification code and the current identification code are checked. Because the third network controls the 7=1 of the crying 3 is “〇,,” and the identification code of the operation command has been the same as the target number of the two people, the system ID is the same. And execute operation instructions to perform related operations. The “Operational Code” operation instruction includes “data write operation, or take operation:”. "So, when the third network controller 220_3 connector is called "data write operation," the third network control two - θ will write the data included in the operation command to the third Network: β 220" in the scratchpad or memory for subsequent related operations> Aspect 'When the third network controller receives the operation command is poor; ^ when the operation is 'the third cigarette The road control (4) 22Q-3 will read the data from the third port, the 're-channel control thief 220-3 register or memory, and generate 201101762 3n^«twraoc/n 5 to take 5 holes, and will buy § The information is transmitted through the first interface of the third network control community 220 3 , wherein the read message includes a read message identifier 2. In this embodiment, the read message identifier is set to “〇”, but not Limit the scope, that is, the user can change the settings by themselves. Then, when the second interface of the two network controllers 22〇_2 receives the read message, the second network controller 220-2 will read the message identifier “0” (read at this time) The message identifier is “〇”) plus the second preset value “Γ (ie, 0+1=1), and the read message is transmitted through the first interface of the second network control pirate 220-2. After the second interface of the first network controller 220J receives the read message, the first network controller 220 detects the code "1" (the message identifier is read at this time). Updated to "r" plus the second preset value "Γ (that is, 1+1 drink, and the read message is transmitted to the processor 21 through the first interface of the ι network controller 22CU, so that the processing is performed The data of the device 21 is read from the third network controller 220-3. The network control H 220HN of the embodiment does not need the special identification code. 'Rather, by using the identification of the decrementing operation command = secret command, or incrementally reading the subtraction code, the design complexity can be reduced. In addition, at 220 Γ ^ Ο立二—'The ground plane of the P-seat board will not be cut into multiple parts, because the effective avoidance of electromagnetic interference is caused by the fact that in the present η% example, the first 10 x.doc/n 201101762 interface), and the second interface is an Electronically Erasable Programmable Read Only Memory (EEPROM) interface. It is worth mentioning that the device code of the above network controller 22 is "0", the first ship value and the first tilt value are set to 1, and the read message identification code is set to "〇". For the sole purpose of the present invention, the invention is not limited thereto. In addition, the recognition of the operation command = the benefit of the network controller to control which network controller is to be changed, and the general knowledge person 'replaces the above S3 _ _ _ description 'to push the other way of doing the embodiment' I will not repeat them here. The law, the example ' can be summarized - the type of network crack I 2_ operator The method of the elm is described below. The operation of the network device of the field network _ J a instance of the network control (four) at (four) = this ^ example _ road device has more than the second and the network controller has the first interface - interface Cry ° and dress:: Do not code ' * 1 network controller's interface - coupled to the processing state, the first Hg] network w network controller's first -; +1) The first interface is the management interface:: the first number. In this embodiment, the memory is read. - φ money can be planned only by referring to Fig. 3' First, in step S3, the operation instruction has the knowledge (4) and the order 'provided by the processor. Then 2: In the example, the 'operation instruction is the instruction, and check the i-th ,, the s-received operation code and the identification code of the operation instruction 11 201101762 31158twf.doc/n are determined. Do not execute the operation instructions to perform related operations. In order to more clearly describe the steps of the above-described operation method, an embodiment will be further described below to explain the detailed flow of the operation method of the present invention. FIG. 4 is a flow chart of a method for operating a network device according to another embodiment of the present invention. Referring to Fig. 4, in step S410, an operation command is provided, which instructs the identification code. In this embodiment the 'operational instructions' are provided by the processor. Next, in step S420, the i th network controller receives the operation command, and i is a positive integer. Thereafter, in step S430, it is checked whether the device identification code of the i-th network controller 1 is identical to the identification code of the operation command. When it is checked that the device identifier of the first network controller is different from the identifier of the operation protector, proceeding to step S440, the identification of the operation finger is subtracted from the first preset value, and the operation command is transmitted through The second interface of the third network controller is transmitted to the first interface of the (i+1)th network controller. Returning to step S430 and step S440, a subsequent operation is performed. On the other hand, when the device identification code of the network controller is the same, the step S45〇' is executed to perform the related operation #. In this embodiment, the operation instruction may be an operation or a data read conversion. Therefore, when the operation instruction is the data write 2, the process proceeds to step S451 to write the data into the sub-mechanism or the memory of the "fixed network controller", wherein the above: # material is included in the operation instruction. When the operation instruction is a data reading operation, the second is read from the register or the memory of the network controller, and the raw item is taken: 'the first through the i-th network controller. 3 The society reads the message, and the above _ take message includes - read = 12
