如果有接收現(xiàn)場總線的信號，還需要接收現(xiàn)場總線信號的功能塊。另外有4塊與網(wǎng)絡(luò)相連的功能塊。他們分別是：模擬量網(wǎng)絡(luò)輸入、模擬量網(wǎng)絡(luò)輸出、開關(guān)量網(wǎng)絡(luò)輸入、開關(guān)量網(wǎng)絡(luò)輸出。其次是PID功能塊、站功能塊，再其次是算術(shù)運算（加、減、乘、除）。然后才是函數(shù)運算（一次濾波、超前-滯后、二維曲線等）、三角幾何運算（正弦、余弦、正切、余切等）和三維矩陣運算。一些高級運算，如模糊邏輯，模型控制等是可多可少的，但它們是判斷DCS系統(tǒng)功能強弱的標(biāo)準(zhǔn)。至于一些行業(yè)的被控對象功能必須有一些特殊的硬件支持，如：電廠的SOE功能
