ATV61HD15Y變頻器

數字量/模擬量輸出表規定的是當CPU處於停機（STOP）狀態時，數字量輸出點或者模擬量輸出通道如何操作。

此功能對於一些保持動作、運轉的設備非常重要。如抱閘，或者一些關鍵的閥門等，不允許在調試PLC時停止動作，就在係統塊的輸出表中進行設置。

數字量：在選中“Freezeoutputinlaststate”後，凍結後的狀態，則在CPU進入STOP狀態時數字量輸出點保持停機前的狀態（是1仍然是1，是0保持為0），同時下面的b.表不起作用如果未選中，那麼選中的輸出點會保持ON（1）的狀態，未選中的為0。

模擬量：在選中“Freezeoutputinlaststate”後，凍結後的狀態，則在CPU進入STOP狀態時模擬量輸出通道保持停機前的狀態，同時下面的表不起作用，未選中時.在下面表中各個規定模擬量輸出通道在答：完全可以，STEP 7 MicroWIN V4.0SP4是S7-200PLC的編程軟件，而STEP7_V5.4_SP3_CN 是S7-300/400係列產品的編程軟件。互不幹擾。 CPU進入STOP狀態時的輸出值。

CPU中的V存儲區（數據塊）中為TD 200分配的參數塊地址又被其它程序重復使用，改變了TD 200參數塊首地址中的信息（ASCII字符'TD'）。

CPU存儲區中TD 200參數塊的首地址，與TD 200中Setup菜單中的設置不同。這種現象常出現在更換TD 200備件時。

一個CPU可以連接幾個TD 200？一個TD 200可以連接幾個CPU？

CPU通訊口可以連接3個TD 200。如果每個TD 200的數據塊各不相同，要注意在TD 200中所能設置的數據塊起始地址大為VB999。

如果CPU上的通訊口被佔用，或者連接數目不夠，可以在CPU上附加EM277模塊（CPU221除外），EM277的連接數是5個TD 200。

一個TD 200在一個時刻只能與一個CPU通訊。

問：剛接觸西門子S7-300 PLC與MM440變頻器通過DP通信，其中資料提到PKW PZD,比如在讀寫0002-1999的參數時，"如讀P1082, 1082=43A(HEX)

PLC PKW輸出=143A,0000,0000,0000 1為讀請求。PLC PKW輸入=243A,0000,4248,0000 返回2為雙字長。值為42480000（HEX)=50.0(REAL)"其中“值為42480000（HEX)=50.0(REAL)是怎麼算的？

答：實數也稱單精度數符號位1位，階碼8位，尾數23位

第一步,化為2進制

第二步:因為IEEE754使用1個符號,8個階碼,23個尾數,

第三步:根據公式寫出實際數值大小

二：基礎知識擴展

DW#16#42480000用2進制表示是0100 0010 0100 1000 0000 0000 0000 0000.

根據IEEE(32)REAL的定義你可以手動進行計算把這些2進制轉為REAL=[1+(2的22次方+2的19次方)*2的（-23）次方]*2的(132-127)次方=50.0
