9.12 Constants
9.12.1Decimal constant (K)
(1) Definition
The decimal constant (K) is used to specify decimal data in sequence programs.
Specify it as K (example: K1234) in sequence programs.
In the CPU module, data are stored in binary (BIN). ( Section 2.4.1)
(2) Specification range
The specification ranges for decimal constants are as follows:
• When using word data (16-bit data) •••••••••••••••••••••••••••••••• K-32768 to K32767
• When using 2-word data (32-bit data)•••••••••••••••••••••••••••••• K-2147483648 to K2147483647
The most significant bit represents a sign bit.
9.12.2Hexadecimal constant (H)
(1) Definition
The hexadecimal constant (H) is a device for specifying hexadecimal or BCD data in sequence programs.
(For BCD data, each digit of a hexadecimal number is specified with 0 to 9.)
In sequence programs, specify it as H (example: H1234). ( Section 2.4.2)
(2) Specification range
The specification ranges for hexadecimal constants are as follows:
• When using word data (16-bit data) ••• H0 to HFFFF (For BCD data, H0 to H9999)
• When using 2-word data (32-bit data) ••• H0 to HFFFFFFFF (For BCD data, H0 to H99999999)
