This section explains the operation processings of the built-in PLC function in each operating status. (1) Operation processing in RUN status A RUN status indicates that a sequence program repeats its operation in order of step 0 to END (FEND) instruction to step 0 when SQ-SD are shorted.

    3.6 I/O Processing Method The control system is a refresh system. 3.6.1 What is refresh system? In the refresh system, control input terminal changes are batch-imported into the input data memory of the CPU before execution of each scan, and the data of this input data memory are used as the input data for operation execution.

  • Page 77: Numerical Values Usable In Sequence Program

    Numerical Values Usable in Sequence Program 3.8 Numerical Values Usable in Sequence Program The built-in PLC function represents numerical values, alphabets and other data in two statuses: 0 (OFF) and 1 (ON). The data represented by these 0s and 1s are called BIN (binary code). The built-in PLC function can also use HEX (hexadecimal code) that represents BIN data in blocks of four bits.
  • Page 78: Bin (binary Code)

    3.8.1 BIN (Binary Code) (1) Binary code BIN is a numerical value represented by 0s (OFF) and 1s (ON). In the decimal code, a number is incremented from 0 to 9, and at this point, a carry occurs and the number is incremented to 10. In BIN, 0, 1 are followed by a carry, and the number is incremented to 10 (2 in decimal).
