Used for a timer number, Timer Completion Flag, or timer present value.
Note: TIMERs can be used only for CJ2 CPU Units with unit version 1.0 or later
and only with CX-Programmer version 8.3.
Used for a counter number, Counter Completion Flag, or counter present value.

data type is used.
Format
Binary Address of a long integer
Decimal A literal value - not an address. 'NUMBER'
type symbols can be used for numeric
operands which are usually prefixed with
'#','&', '+' or '-'. They can be used in BCD or
binary instructions. For BCD usage, the
value is treated as if entered in hex (e.g. the
number '1234' has the same effect as
entering '#1234' in the operand).
A floating-point value can be entered (e.g.
'3.1416'). An engineering format number
can be entered (e.g. '-1.1e4').
A decimal value is assumed. A
hexadecimal value can be entered using a
prefix of '#'.
IEEE Address of a floating-point number. The
format is the 32-bit IEEE format. For the
special OMRON floating point format (FDIV
instruction) use the UDINT_BCD type.
IEEE Address of a floating-point number. The
format is the 64-bit IEEE format.
Binary Address of an unsigned double integer
BCD Address of an unsigned double BCD
integer
Binary Address of an unsigned integer
BCD Address of an unsigned BCD integer
Binary Address of an unsigned long integer
BCD Address of an unsigned long BCD integer
Any Address of a bit string of 16 bits.
Any Address of a bit string of 32 bits.
Any Address of a bit string of 64 bits.
ASCII The data is handled as character strings.
The size can be set between 1 and 255
characters.
