Fig. 7 is the process flow diagram of exemplary embodiment that is used to use the method 7000 of this memory device.At action 7100 places, this user can allow the element of selection at the item file of the storage on this memory device in being prompted property ground.The information, expression that this selectable element can comprise this item file, this program, this prescription, expression recipe structure and the information of the data log files structure of data log files separate storage and/or belong to this process, PLC, the hardware relevant and/or the supporting documentation of the software of being correlated with PLC with PLC.
At action 7200 places, can from selection equipment, be received corresponding to the user input of the option of at least one project file element of storage.Offer the user storage option and can allow this customization storage plan, to be fit to the demand of unique system, this demand is considered such factor: be used for storing other device, the storage box of this item file size, at the quantity of the collected process data of the storage of data log files, storage at the frequency of the collected process data of the storage in the data log files, in this memory device the quantity of storable prescription number and/or available supporting documentation and/or content or the like.
At action 7300 places, in response to user's input, project file element can be written in the memory device.This project file element can be written in the section start of vacant memory segment.Replacedly, project file element can cover previously stored item file.
Fig. 8 is the process flow diagram of exemplary embodiment that is used to use the method 8000 of this storage box.At action 8100 places, first head marker of the initial memory paragraph of the data log record of indicating to be written into can be positioned on the memory device.This data log record can be the size that can be stored on the single memory paragraph.Replacedly, this data log record can be the size that can be stored on a plurality of memory paragraphs.For data log storage can with memory paragraph can be space and/or contiguous in logic, and/or can write continuously.
At action 8200 places, the data log record that can comprise second head marker can be written into initial at least memory paragraph.This data log record can be written on one vacant memory segment at least.
Replacedly, this data log record can cover the memory paragraph that at least one is used by older data log record.This second head marker can comprise the information of reflection at the position of the next memory paragraph of the storage of next data log record.In the exemplary embodiment, this data log files can be written in logic in the round-robin impact damper.This in logic the round-robin impact damper be characterised in that the data log record that writes contiguous memory segments, this impact damper begins at initial memory paragraph place.When this impact damper is full of, this in logic the round-robin impact damper be further characterized in that writing in the next data log record of the section start of this impact damper.Next data log record can cover writes logically the oldest data log record in the round-robin impact damper.For example, if this impact damper is full, the then next data log record that will be written into can be written in the section start of this impact damper, therefore covers before the data log record at the section start of this impact damper.This in logic the round-robin impact damper can comprise cyclic buffer, wherein memory paragraph is physically mutually contiguous.
At action 8300 places, first head marker can be changed into the record mark that reflection writes on the data log record in the initial at least memory paragraph.This record mark (as change) success that can represent to comprise the data log record of second head marker writes.
After action 8200 and before complete execution 8300, power fail may occur.Occurring power fail before finishing fully in action 8300 can stay and have the data log files that two head markers are opened simultaneously.At action 8400 places, in effective embodiment, PLC can guarantee the power fail existence of single head marker afterwards via the error checking technology.The accurate verification of the method that this error checking technology can be any compensation, Fletcher verification and method, cyclic redundancy check method and/or expansion and method etc.May with the position of problematic record and be added to the position of record of memory device and/or error checking technology that the knowledge of direction is relevant can to identify which record be up-to-date, and therefore to identify which head marker be wrong.
In effective embodiment, PLC can forbid and/or eliminate head marker older, that duplicate, perhaps will be older, that duplicate possibly head marker is converted to and causes the non-head marker that single head marker occurs in the data log files, and this single head marker is corresponding to new record.The value that changes binary digit can be forbidden head marker older, that duplicate.Replacedly, on each of this data log record, PLC can check and test the sign such as the timestamp sign, to determine the up-to-date record that writes.
At action 8400 places, this data log record can be read from this memory device.In effective embodiment, in response to data log structure, this data log record can read from least one memory paragraph.Represent the information of this data log structure can separate storage in this memory device.
Also have other embodiment from accompanying drawing, will become easy with above-mentioned detailed description and some exemplary embodiment for those skilled in the art.Should be appreciated that various variations, modification and additional embodiments are possible, and thereby all such variations, modification and embodiment will be considered in the spirit and scope of appended claim.For example, no matter the content of any part (for example title, chapters and sections, summary, accompanying drawing or the like) of this application, unless clear and definite regulation on the contrary, otherwise without any the needs of the mutual relationship of the action that specifies or illustrate or element, any specific such running order or any specific such element.In addition, any action can be repeated, and any action can be carried out by a plurality of entities, and/or any element can be replicated.Moreover any action or element can be excluded, and the order of action can change, and/or the mutual relationship of element can change.Therefore, this instructions and accompanying drawing essence are considered to exemplary, rather than restrictive.
