(example: K1234) in a sequence program.
It is stored in binary (BIN) into the CPU module. ( Section 3.7.1)
(2) Designation range
The designation ranges for decimal constants are as follows:
• For word data (16 bits)••••••••••••••••••••••••••K-32768 to 32767
• For 2-word data (32 bits) •••••••••••••••••••••••K-2147483648 to 2147483647
POINT
The most significant bit is a sign bit.
9.5.2 Hexadecimal constant (H)
(1) Definition
Hexadecimal constants are devices which designate hexadecimal or BCD data in
sequence programs.
(For BCD data designations, 0 to 9 digit designations are used.)
Hexadecimal constants are designated as "H
" settings (e.g. H1234).
( Section 3.7.2)
(2) Designation range
The setting ranges for hexadecimal constants are as follows:
• For word data (16 bits)••••••••••••••••••••••••••H0 to FFFF
(H0 to 9999 for BCD)
• For 2-word data (32 bits) •••••••••••••••••••••••H0 to FFFFFFFF
(H0 to 99999999 for BCD)
