70 I/O Processing Met hod 3.6.2 Response delay in refres h system This section describes a delay of an output change in response to an input change. An output change in response to an input change has a del ay of up to two scans as shown in Fig. 2.6. Fig 3.
71 Scan Time 3 SEQUENCE PROGRAMMING 3.7 Scan Ti me (1) Scan time A scan time is a time from when s equence program operation is executed from step 0 until step 0 is executed again. The scan time of each s can is not equal, and changes depending on whether the used instructions are executed or not.
72 Numerica l Values Usable in Sequence Pro gram 3.8 Numerical V alues Usable i n Sequence Pr ogram The built-in PLC function represents numer ical values, alphabet s and other data in two statuses: 0 (OFF) and 1 (ON). The data represented by these 0s and 1s are called BIN (binary code).
73 Numeric al Values Usabl e in Sequen ce Program 3 SEQUENCE PROGRAMMING 3.8.1 BIN (Bin ary Co de) (1) Binary code BIN is a numerical value represented by 0s (OFF) and 1s (ON).
