1756-SYNCH-CC電路板設(shè)計
具有輸入、輸出參數(shù)和局部變量的子程序易于實現(xiàn)結(jié)構(gòu)化編程，對于長期生產(chǎn)同類設(shè)備或生產(chǎn)線的廠家尤為有用。這些廠家的編程人員為設(shè)備的各組件或工藝功能編寫了大量的通用的子程序。即使不知道子程序的內(nèi)部代碼，只要知道子程序的功能和輸入、輸出參數(shù)的意義，就可以通序之間的調(diào)用快速“組裝”出不同用戶要求的控制程序。就好像用數(shù)字集成電路芯片組成復(fù)雜的數(shù)字電路一樣。子程序如果沒有輸入、輸出參數(shù)，它和調(diào)用它的程序之間沒有清晰的接口，很難實現(xiàn)結(jié)構(gòu)化編程。子程序如果沒有局部變量，它和調(diào)用它的程序之間只能通過全局變量來交換數(shù)據(jù)，子程序內(nèi)部也只能使用全局變量。將子程序和中斷程序移植到別的項目時，需要重新統(tǒng)一安排它們使用的全局變量，以不會出現(xiàn)地址沖突。當(dāng)程序很復(fù)雜，子程序和中斷程序很多時，這種重新分配地址的工作量非常大。如程序和中斷程序有局部變量，并且它們內(nèi)部只使用局部變量，不使用全局變量，因為與其他POU沒有地址沖突，不需作任何改動，就可以將子程序移植到別的項目中去。
