PROSOFT MVI56-PDPS CPU模塊
有人建議，它與MVI56-PDPS控制器中標記的標簽相似。寄存器/線圈要訪問的狀態(tài)RAM的所需區(qū)域。這四個區(qū)域是線圈（0x0000）、輸入狀態(tài)位（1x0000）、輸入寄存器（3x0000）和保持寄存器（4x0000）。每個區(qū)域名稱后面都是概念（直接）地址的最高有效數(shù)字，如括號所示。偏移要訪問的數(shù)據(jù)在狀態(tài)RAM內(nèi)的所需偏移量。這與寄存器/線圈選擇相結(jié)合，將確定要訪問的數(shù)據(jù)的完整地址。例如，選擇偏移量為00180的保持寄存器將產(chǎn)生400180的最終地址。數(shù)據(jù)類型訪問數(shù)據(jù)所需的格式。寄存器/線圈類型的線圈和輸入位只能作為byte_bools訪問?？梢酝ㄟ^以下方式之一訪問寄存器：§ Int16-16位有符號整數(shù)§ MVI56-PDPS位有符號長整數(shù)§ Uint16-16位無符號整數(shù)§ MVI56-PDPS位無符號長整數(shù)§ Float32-32位浮點元素數(shù)要訪問的元素數(shù)。這允許陣列傳輸。使用“西門子S7新標簽”對話框?qū)碜晕鏖T子S7控制器的標簽添加到模塊配置中。要打開“西門子S7新標記”對話框，請在“配置編輯器”樹中選擇西門子S7控制器下的“標記”節(jié)點，然后單擊工具欄上的“新建”按鈕。參數(shù)描述標記名稱所需的標記名稱，完全由用戶決定。建議其與西門子S7控制器中標記的標簽相似。地址類型要訪問的內(nèi)存類型：輸入、輸出、外圍輸入、標志位、定時器、計數(shù)器或數(shù)據(jù)塊。輸入包含輸入模塊最后一次掃描的存儲器。該區(qū)域的S7符號（IEC）為“I”。此內(nèi)存是只讀的，用于模塊訪問。輸出在下一個掃描周期結(jié)束時，包含要寫入輸出模塊的所需輸出值的存儲器。
與標記關聯(lián)的圖元的名稱、數(shù)據(jù)類型和數(shù)量顯示在“新建標記”對話框的右側(cè)。您不能修改任何標記值。單擊ADD（添加）按鈕，將Tag（標記）參考添加到模塊的配置中。單擊“完成”關閉“新建標記”對話框。當該對話框首次出現(xiàn)時，“標記”樹中不會顯示任何標記。對話框頂部是一個名為“標記過濾器”的編輯框。輸入標記的過濾器，然后單擊“獲取標記”按鈕或按[Enter]鍵。所有與指定篩選器匹配的標記都將加載到標記樹中?；蛘?，要獲取所有標記，請將標記過濾器留空，然后單擊“獲取標記”按鈕或按[ENTER]鍵。另請參閱標記過濾器（第72頁）。將與過濾器匹配的標記加載到標記樹中后，選擇一個標記。MVI56-PDPS與標記關聯(lián)的圖元的名稱、數(shù)據(jù)類型和數(shù)量顯示在“新建標記”對話框的右側(cè)。您不能修改任何標記值。單擊ADD（添加）按鈕，將Tag（標記）參考添加到模塊的配置中。單擊“完成”關閉“新建標記”對話框。當對話框首次出現(xiàn)時，位置樹將加載控制器內(nèi)的標記位置。對于PLC5、MicroLogix或SLC，這些都是文件參考。在位置樹中選擇標記位置。MVI56-PDPS標記關聯(lián)的“文件地址”、“數(shù)據(jù)類型”和“名稱”顯示在“新建標記”對話框的右側(cè)。您可以將標記的名稱修改為對您有意義的標記名稱。您可以修改元素的數(shù)量，以指定此位置將有多少數(shù)據(jù)項與此標記關聯(lián)。當元素數(shù)大于1時，此標記將作為數(shù)組處理。單擊添加按鈕將標記添加到模塊的配置中。單擊完成關閉PLC5、MicroLogix和SLC新標簽對話框使用Modbus TCP/IP新標簽對話框?qū)chneider Electric Quantum PLC（Unity或Concept）控制器的標簽添加到模塊配置中。要打開Modbus TCP/IP新標簽對話框，請在配置編輯器樹中選擇Schneider Electric Quantum PLC控制器下的標簽節(jié)點，然后單擊工具欄上的New按鈕參數(shù)描述標簽名稱所需的標簽名稱，完全由用戶決定。
They may contain the following data types: BOOL, BYTE, WORD, DWORD, INT, DINT, REAL, S5TIME, DATE, TIME, TIME_OF_DAY, CHAR, DATE_AND_TIME, STRING, or ARRAY. Descriptions of these data types should be available in the S7 PLC or Step 7 Programming Software documentation. This memory is read/write for module access. DB Number The number of the desired Data Block to access. This field is only valid if the Address Type selected is Data Blocks (DB). Offset The desired offset/number of the associated Address Type element. The following is a description of this field’s meaning for each address type: Input, Peripheral Input & Output Enter the slot number of the desired I/O module. Flag Bit Enter the byte offset within the Flag Bit memory of the desired location. Timers & Counters Enter the number of the desired timer or counter. Data Blocks Enter the number of the desired data block. Bit ID The desired bit number within the data element.MVI56-PDPS Data Type The desired format for accessing the data. This field depends on the selected Address Type.
The S7 notation (IEC) for this area is "PI". This area is read only for module access. Flag Bit The memory that is intended to store interim results calculated in the program of the PLC. The S7 notation (IEC) for this area is "M". This memory is read/write for module access.MVI56-PDPS Timers The memory that contains the accumulators for the timers in the S7 PLC. The S7 notation (IEC) for the timers is "T". This memory is read only for module access and the format is in BCD. The number represents the number of milliseconds that the timer has been active with a maximum value of 3999. Counters The memory that contains the accumulators for the counters in the S7. The S7 notation (IEC) for the counters is "C". This memory is read only for module access and the format is in BCD. The number represents the accumulated value of the counter since the counter has been active with a maximum value of 999.·Parameter Description Data Blocks The memory that contains information for the program of the S7 PLC.
Use the Siemens S7 New Tag dialog box to add Tags from a Siemens S7 controller to the module's configuration.
