    每個(gè)模塊的塊結(jié)構(gòu)塊類型取決于塊的數(shù)據(jù)內(nèi)容和功能。模塊使用以下塊標(biāo)識(shí)號(hào):塊ID范圍描述-1個(gè)空塊

    ? 如果在模塊配置文件中設(shè)置了讀取寄存器計(jì)數(shù)>200字,塊ID 0未使用。

    ? 如果模塊配置文件中的讀取寄存器計(jì)數(shù)設(shè)置為>0

    且<=200個(gè)字,塊ID包含與塊1相同的數(shù)據(jù)(讀取數(shù)據(jù)和狀態(tài)數(shù)據(jù))。讀取塊ID是一個(gè)索引值,用于確定200字?jǐn)?shù)據(jù)的位置模塊內(nèi)存中的ControlLogix處理器。每次傳輸最多可以移動(dòng)200個(gè)字(塊偏移量2到201)的數(shù)據(jù)。除了移動(dòng)用戶數(shù)據(jù)外,塊還包含單元與塊關(guān)聯(lián)的寫塊ID從ControlLogix處理器。

    Module’s Internal Database Structure

    All data transferred between the module and the processor over the backplane is through the input and output images. Ladder logic must be written in the ControlLogix processor to interface the input and output image data with data defined in the controller tags. All data used by the module is stored in its internal database. This database is defined as a data table with addresses from 0 to 4999

    Data contained in this database is transferred in blocks, or pages, using the input and output images. ControlLogix ladder logic and the MVI56E-SIE module's program work together to coordinate these block transfers. Up to 200 words of data can be transferred from the module to the processor (read block - input image) or from the processor to the module (write block - output image) in each block transfer. The block structure of each block type depends on the data content and function of the block. The module uses the following block identification numbers: Block ID Range Descriptions -1 Null block 0 This feature enhances performance, especially when using less than 200 words of read/write data: ? If Read Register Count in the module configuration file is set > 200 words, Block ID 0 is not used. ? If Read Register Count in the module configuration file is set >0 and <= 200 words, Block ID contains the same data as block 1 (both read data and status data).

    Normal Data Transfer Blocks 

    Normal data transfer includes the paging of user data from the module’s internal database (registers 0 to 4999), as well as paging of status data. These data are transferred through read (input image) and write (output image) blocks. The following topics describe the function and structure of each block. Read Block These blocks of data transfer information from the module to the ControlLogix processor. The following table describes the structure of the input image.The Read Block ID is an index value used to determine where the 200 words of data from module memory will be placed in the ReadData[x] controller tag array of the ControlLogix processor. Each transfer can move up to 200 words (block offsets 2 to 201) of data. In addition to moving user data, the block also contains status data for the module. The Write Block ID associated with the block requests data from the ControlLogix processor. During normal program operation, the module sequentially sends read blocks and requests write blocks. For example, if the application uses three read and two write blocks, the sequence will be as follows: R1W1>R2W2>R3W1>R1W2>R2W1>R3W2>R1W1> This sequence will continue until interrupted by other write block numbers sent by the controller or by a command request from a node on the Siemens Industrial Ethernet network or operator control through the module’s Configuration/Debug port.
