PLCopen庫的應用舉例
例1:印刷機的控制開發(fā)
對于印刷機械而言，其核心在于印刷套色，基于PLCopen的庫，我們可以通過圖中的功能塊RegMarkCapture001來進行色標的抓取，通過RegMarkCacl001進行色標偏差的計算和解耦算法，并通過Offset進行相位偏移的控制輸出，這三個功能塊可以實現(xiàn)對印刷的套色計算和控制，結合速度控制模塊、扭矩控制實現(xiàn)對張力控制的計算。
除了應用于凹版印刷機的套色控制，PLCopen在柔版、商業(yè)輪轉(zhuǎn)機等高性能卷筒紙印刷領域也得到了廣泛應用，大大降低了開發(fā)周期。
例2：PLCopen庫在旋蓋控制中的應用
在啤酒飲料灌裝系統(tǒng)中，如何實現(xiàn)更高效且高品質(zhì)的旋蓋控制，即可借助于PLCopen的庫：
對于旋蓋而言，角度控制MC_MoveAdditive可以提高速度，它可以確保旋蓋過程以極大的速度進行，但是，卻不能保障每個旋蓋動作的扭矩控制質(zhì)量，通過TorqueControl模塊，可以確保每個瓶蓋的相同力矩，確保旋蓋質(zhì)量的一致性，但是，TorqueControl卻會降低效率，因為不能過高的速度，否則會將瓶子損壞。
因此，通過MC_MoveAdditive和MC_BR_TorqueControl的混合使用可以確保高品質(zhì)同時高速的旋蓋控制。
例3：PLCopen Safety安全庫的應用
仍然以啤酒飲料灌裝設備來看，對于高速運轉(zhuǎn)的機器，必須考慮人身的安全以及設備的運行安全，尤其是對連續(xù)生產(chǎn)的智能產(chǎn)線而言，其由吹瓶、清洗、灌裝、旋蓋、貼標、膜包等一系列流程構成，如果某個單元出現(xiàn)安全動作，則整個生產(chǎn)線將因此停滯，帶來巨大的潛在浪費，而SLS和STO可以解決這一問題，通過PLCopen Safety庫設計，我們可以實現(xiàn)兩個安全功能來確保生產(chǎn)效率與安全的平衡。
1. SLS降低產(chǎn)線速度，低速運行的機器將會帶給人身風險的極大下降，通常在人員進入機器的安全區(qū)則速度下降，如從10m/S的線速度下降到0.5m/S，則會大幅度降低傳動設備對人身的潛在傷害，而同時產(chǎn)線并不會因此停止帶來再開機的成本以及在制品的浪費。
2. STO，通過伺服驅(qū)動的待機狀態(tài)，在人員進入工作區(qū)，僅切斷力矩輸出，而不切斷電源，確保機器處于安全狀態(tài)，在人員離開后，重新啟動工作，從當前位置繼續(xù)。
此兩者均是基于生產(chǎn)效率與安全的平衡設計，可以通過PLCopen的Safety庫軟件設計來實現(xiàn)
