其次，用戶需要設(shè)置計(jì)數(shù)器的初始值和上下限。初始值表示計(jì)數(shù)器的起始數(shù)值，上下限表示計(jì)數(shù)器的計(jì)數(shù)范圍。超出上下限后，計(jì)數(shù)器將停止計(jì)數(shù)或重新計(jì)數(shù)。通過(guò)設(shè)置初始值和上下限，用戶可以靈活地控制計(jì)數(shù)器的計(jì)數(shù)范圍，滿足不同需求。用戶需要設(shè)置輸入信號(hào)的觸發(fā)條件。
S7-1200 PLC支持多種觸發(fā)條件，例如上升沿觸發(fā)、下降沿觸發(fā)、邊沿觸發(fā)和電平觸發(fā)等。用戶可以根據(jù)實(shí)際需要選擇合適的觸發(fā)條件。觸發(fā)條件決定了計(jì)數(shù)器在何時(shí)開(kāi)始計(jì)數(shù)。一旦滿足觸發(fā)條件，計(jì)數(shù)器將開(kāi)始計(jì)數(shù)，并按照設(shè)定的計(jì)數(shù)方向和規(guī)則進(jìn)行計(jì)數(shù)。
Secondly, users need to set the initial value and upper and lower limits of the counter. The initial value represents the starting value of the counter, and the upper and lower limits represent the counting range of the counter. After exceeding the upper and lower limits, the counter will stop counting or count again. By setting the initial value and upper and lower limits, users can flexibly control the counting range of the counter to meet different needs. Finally, the user needs to set the triggering conditions for the input signal.
The S7-1200 PLC supports multiple triggering conditions, such as rising edge triggering, falling edge triggering, edge triggering, and level triggering. Users can choose appropriate triggering conditions according to their actual needs. The triggering condition determines when the counter starts counting. Once the triggering conditions are met, the counter will start counting and count according to the set counting direction and rules.
