Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the embodiments of the present invention are explained in detail.But, persons of ordinary skill in the art may appreciate that in each execution mode of the present invention, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following execution mode and amendment, each claim of the application technical scheme required for protection also can be realized.
In embodiments of the present invention, as shown in Figure 1, a main equipment and multiple from equipment is comprised.In advance according to the input and output attribute respectively from equipment, for each from equipment assignment logic address.Wherein, the input with input attributes, from least corresponding output with output attribute of equipment from equipment, inputs and is assigned identical logical address with corresponding output from equipment from equipment; Make the input with same logical address can realize direct communication from equipment and each output between equipment.Can save to a certain extent export from equipment by main equipment and input from the communication cycle between equipment, thus can to a certain extent by communication delay control in the short period of time.Wherein, for each logical address of distributing from equipment comprises initial address and the length of logical address.
It should be noted that, in advance according to the input and output attribute respectively from equipment, for each from the step of equipment assignment logic address, utilize respectively from logical address described in the register configuration of equipment.Utilize and respectively make its configuration mode comparatively simple from the register configuration logical address of equipment, thus make the present invention have more practicality.
First execution mode of the present invention relate in a kind of network from devices communicating method.It should be noted that main equipment in present embodiment periodically to communicate to connect with it from equipment sending data bag.Wherein, the transmission cycle of packet can be set to 1 millisecond; Also according to the needs of actual design, other cycle can be designed to, not limit at this.
It is worth mentioning that, the input of present embodiment can be approximated to be collecting device from equipment, as shown in Figure 2, input the harvester at least comprising communication control module ESC, the processor CPU communicated with described ESC from equipment and communicate to connect with CPU, wherein acquisition module can be, but not limited to as signal lamp 1, and inputting can by the state information of the signal lamp 1 collected by being stored into the respective memory unit of described ESC from equipment after CPU process.
Input the workflow diagram from equipment, as shown in Figure 3, step is as follows: in a step 101, inputs and judges that whether this is identical with the logical address of carrying the packet that main equipment sends from the logical address of equipment from equipment.If identical, then enter step 102; Otherwise, enter step 101.
Specifically, input the logical address comprised the packet received by input interface from equipment Inspection, whether the logical address configured from equipment with this is consistent, when testing result is consistent, then enters step 102.Otherwise, enter step 101.
In a step 102, to input from equipment according to logical address and mapping relations, find corresponding local physical address.
It should be noted that, in present embodiment in advance for respectively from equipment arrange local physical address with above-mentioned be the mapping relations of each logical address of distributing from equipment in advance.Namely this input is the logical address that this distributes from equipment from the local physical address of equipment and main equipment is one to one.Wherein, input comprises FMMU (FMMU refers to field bus management unit) register from equipment, FMMU is used for management input from the logical address of equipment and the mapping relations of local physical address, as shown in Figure 4, the data of a-quadrant poke are the initial address of this input from the logical address of equipment.The data of B region poke are the length of this input from the logical address of equipment.The data of C region poke are the initial address of this input from the local physical address of equipment.It should be noted that, this input is exactly the length of described logical address from the length of the local physical address of equipment, stores without the need to arranging storage area in FMMU separately.
Specifically, inputting can according to the initial address of the logical address of carrying packet from equipment, the initial address of the physical address that the initial address of the known and described logical address of mapping relations stored in conjunction with FMMU is corresponding.The length of corresponding physical address is known according to the length of the logical address of carrying in packet.And then corresponding local physical address can be found.
Then, enter step 103, input the information will stored in the local physical address found from equipment, write this packet as the information of corresponding output from equipment need be transferred to.
It should be noted that, input, from equipment, there is input interface and output interface.In present embodiment, the packet that main equipment sends, through input from device transmission to exporting from equipment accordingly.The i.e. packet that sends of main equipment, through input from the input interface of equipment, and to be transferred to from the output interface of equipment by input and exports from equipment accordingly.
Export the workflow diagram from equipment, as shown in Figure 5, step is as follows: in step 104, exports and judges that whether this is identical with the logical address of carrying the packet received from the logical address of equipment from equipment.If identical, enter step 105, otherwise enter step 104.
This step is similar to step 101, does not repeat them here.
In step 105, to export from equipment according to the logical address of carrying packet and mapping relations, find corresponding local physical address.
This step is similar to step 102, does not repeat them here.
Then, enter step 106, export the information will read from this packet from equipment, be stored in the local physical address that finds.
In present embodiment, from equipment and from can direct communication between equipment, and without the need to being realized by main equipment from equipment and the indirect communication from equipment.Can save to a certain extent from equipment by main equipment and other are from the communication cycle between equipment, thus can to a certain extent communication delay be controlled in the short period of time.
Second execution mode of the present invention relate in a kind of network from devices communicating method.Second execution mode is roughly the same with the first execution mode, and main distinction part is: in the first embodiment, and the corresponding input of the packet that main equipment sends is from equipment.And in second embodiment of the invention, as shown in Figure 6, main equipment send a packet can corresponding multiple input from equipment.
