Beifu realizes the control of time slice size and quantity through CTU and ton

In programming , It takes time , That is, jump after the timing of each time slice , You also need to set the number of time slices , for example 4 Time slice , Then poll for a certain time . This article is based on CTU Counting module and TON To implement .
1.1. Biff Beckhoff
1.1.1. CTU Introduce
That is, the rising edge of the input signal is not caught and counted once , Count value reached PV Then output Q,SV As the current count value ,Reset Reset .

1.1.1. TON Introduce
TON The usage of is as follows

1.1.2. actual PLC Program
The implementation principle is to use two TON Realize pulse flicker by interlocking , And then use CTU Record the times and reset to zero when the upper limit is reached , The procedure is as follows ：
