隨著PLC在順序控制上的廣泛使用，也成為在制造業的通用裝置。但你知道在PLC中傳送和比較指令有什么作用呢？若你也對此不了解，就隨儀器儀表世界網小編從下文找到答案吧。
1、 用以獲得程序的初始工作數據
一個控制程序總是需要初始數據。這些數據可以從輸入端口上連接的外部器件獲得，需要使用傳送指令讀取這些器件上的數據并送到內部單元；初始數據也可以用程序設置，即向內部單元傳送立即數；另外，某些運算數據存儲在機內的某個地方，等程序開始運行時通過初始化程序送到工作單元。
2、機內數據的存取管理
在數據運算過程中，機內的數據傳送是不可缺少的。運算可能要涉及不同的工作單元，數據需在他們之間傳送；運算可能會產生一些中間數據，這需要傳送到適當的地方暫時存放；有時機內的數據需要備份保存，這要找地方把這些數據存儲妥當。總之，對一個涉及數據運算的程序，數據管理是很重要的。
此外，二進制和 BCD 碼的轉換在數據管理中也是很重要的。
