如果確實(shí)需要，還可以在程序運(yùn)行中動(dòng)態(tài)定義一個(gè)數(shù)據(jù)塊。動(dòng)態(tài)定義時(shí)，數(shù)據(jù)塊號(hào)是自動(dòng)產(chǎn)生的，數(shù)據(jù)塊在存儲(chǔ)器中的位置是動(dòng)態(tài)分配的。由于要定義的數(shù)據(jù)塊有可能大于CPU存儲(chǔ)器(用于數(shù)據(jù)塊的部分)的剩余空間，因此動(dòng)態(tài)定義過程有可能失敗
2．訪問數(shù)據(jù)塊
在用戶程序中可能定義了許多數(shù)據(jù)塊，而每個(gè)數(shù)據(jù)塊中又有許多不同類型的數(shù)據(jù)，因此，訪問時(shí)需要明確數(shù)據(jù)塊號(hào)和數(shù)據(jù)塊中的數(shù)據(jù)類型與位置。根據(jù)明確數(shù)據(jù)塊號(hào)的不同方法，可以用多種方法訪問數(shù)據(jù)塊中的數(shù)據(jù)。
直接在訪問指令中寫明數(shù)據(jù)塊號(hào)，如：
L DB5.DBW10
T DB10.DBW20
L Motor_1.Speed 符號(hào)地址
另一種方法是“先打開后訪問”。在訪問某數(shù)據(jù)塊中的數(shù)據(jù)前，先“打開”這個(gè)數(shù)據(jù)塊，也就是將數(shù)據(jù)塊號(hào)(數(shù)據(jù)塊的起始地址)裝入數(shù)據(jù)塊寄存器。這樣，存放在數(shù)據(jù)塊中的數(shù)據(jù)就可利用數(shù)據(jù)塊起始地址加偏移量的方法來訪問。如：
OPN DB5
L DBW10
OPN DB10
T DBW20
在打開一個(gè)數(shù)據(jù)塊時(shí)，先打開的數(shù)據(jù)塊會(huì)自動(dòng)關(guān)閉(沒有專門的數(shù)據(jù)塊關(guān)閉指令)。由于有兩個(gè)數(shù)據(jù)塊寄存器(DB和DI寄存器)，因此，多可同時(shí)打開兩個(gè)數(shù)據(jù)塊。一個(gè)作為背景數(shù)據(jù)塊，數(shù)據(jù)塊的起始地址存儲(chǔ)在DI寄存器中；另一個(gè)作為共享數(shù)據(jù)塊，數(shù)據(jù)塊的起始地址存儲(chǔ)在DB寄存器中。打開背景數(shù)據(jù)塊，在調(diào)用FB時(shí)可以自動(dòng)實(shí)現(xiàn)。由于調(diào)用FB時(shí)使用DI寄存器，因此，一般不在FB程序中用OPN DI n指令打開數(shù)據(jù)塊。
3. 背景數(shù)據(jù)塊和共享數(shù)據(jù)塊
背景數(shù)據(jù)塊和共享數(shù)據(jù)塊有不同的用途。任何FB、FC或OB均可讀寫存放在共享數(shù)據(jù)塊中的數(shù)據(jù)。背景數(shù)據(jù)塊是FB運(yùn)行時(shí)的工作存儲(chǔ)區(qū)，它存放FB的部分運(yùn)行變量。調(diào)用FB時(shí)，必須指定一個(gè)相關(guān)的背景數(shù)據(jù)塊。作為規(guī)則，只有FB塊才能訪問存放在背景數(shù)據(jù)塊中的數(shù)據(jù)。
一般情況下，每個(gè)FB都有一個(gè)對(duì)應(yīng)的背景數(shù)據(jù)塊，一個(gè)FB也可以使用不同的背景數(shù)據(jù)塊。如果幾個(gè)FB需要的背景數(shù)據(jù)完全相同，為節(jié)省存儲(chǔ)器，則可以定義成一個(gè)背景數(shù)據(jù)塊，供它們分別使用。通過多重背景數(shù)據(jù)，也可將幾個(gè)FB需要的不同的背景數(shù)據(jù)定義在一個(gè)背景數(shù)據(jù)塊中，以優(yōu)化數(shù)據(jù)管理。各數(shù)據(jù)塊在CPU的存儲(chǔ)器中是沒有區(qū)別的，只是由于打開方式不同，才在打開時(shí)有背景數(shù)據(jù)塊和共享數(shù)據(jù)塊之分。原則上，任何一個(gè)數(shù)據(jù)塊都可以當(dāng)作共享數(shù)據(jù)塊或背景數(shù)據(jù)塊使用，實(shí)際上，一個(gè)數(shù)據(jù)塊由FB當(dāng)作背景數(shù)據(jù)塊使用時(shí)，必須與FB的要求格式相符。
