Hexadecimal
• A hexadecimal value consists of 16 symbols, 0 to 9 and A to F, which represent the order and size (amount). After a digit
reaches F, an increment resets it to 0, causing an increment of the next digit to the left.
• Four bits of a binary value are equivalent to one digit of a hexadecimal value.
• In the programmable controller, the symbol "H" is used to represent a value in hexadecimal.
• Hexadecimal values are used to represent the following device numbers.
• Link relay (B)
