To program well, we need to know binary, decimal, and hexadecimal numbers. The following chart shows the relationships between these notations.

Decimal | Binary | Hexadecimal |
---|---|---|

0 | 0000 | 0 |

1 | 0001 | 1 |

2 | 0010 | 2 |

3 | 0011 | 3 |

4 | 0100 | 4 |

5 | 0101 | 5 |

6 | 0110 | 6 |

7 | 0111 | 7 |

8 | 1000 | 8 |

9 | 1001 | 9 |

10 | 1010 | A |

11 | 1011 | B |

12 | 1100 | C |

13 | 1101 | D |

14 | 1110 | E |

15 | 1111 | F |

In Cubloc’s Ladder Logic, we express binary and hexadecimal numbers in the following manner:

Binary: 00101010B Hexadecimal: 0ABCDH

We put a B at the end of the binary number and an H at the end for hexadecimal numbers. To clearly identify that a hexadecimal value is a number, we can put a 0 in front of the hexadecimal number. (E.g. : 0ABH, 0A1H, 0BCDH )

*BASIC is slightly different from Ladder Logic in the way binary and hexadecimal numbers are expressed. &B100010 is used for binary and &HAB is used for hexadecimal.
