Each program within a PLC has a 'local' symbol table that consists of symbols that are for use specifically in
that program. Each PLC within a project has a 'global' symbol table that consists of symbols that can be used in
any of its programs. When a PLC is added to a project, its global symbol table is filled with a pre-set list of
symbols, dependant upon PLC type.
Each symbol name must be unique within its table. However, it is possible to use the same name in a local and a
global table – in this case, the local symbol takes precedence over the global symbol of the same name.
A literal numeric value - not an address. The value can be signed, or floating
point. NUMBERs are used for any literal value or for timer/counter identifiers
(for TIM/CNT, only unsigned integer values are allowed).
Floating point values are only suitable within IEEE REAL type operands.
Note: When used as BCD number operands, the value is treated as if it were
entered in decimal with a '#' on the front. E.g. using a NUMBER '1234' is
equivalent to typing '#1234' as the operand, so that the decimal
interpretation is made of the value.
The value of a NUMBER data type is assumed to be decimal, unless it is
prefixed with '#' for a hexadecimal value.
Note: NUMBERs entered in hexadecimal are converted to decimal for BCD
operands (e.g. a NUMBER defined as '#10' will appear as '#16' for a BCD
operand).
Address of a double word floating point value (IEEE format - use the UDINT
type for the BCD, FDIV format).
Address of a long word floating point value (IEEE format - use the ULINT
type for the BCD format).
Address of an unsigned, double binary word.
Address of an unsigned, double BCD word.
Address of an unsigned, single binary word.
Address of an unsigned, single BCD word
Address of an unsigned, quad binary word.
Address of an unsigned, quad BCD word.
Address of a bit string of 16 bits.
Address of a bit string of 32 bits.
Address of a bit string of 64 bits.
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.
Note: COUNTERs can be used only for CJ2 CPU Units with unit version 1.0
or later and only with CX-Programmer version 8.3.
The data is handled as character strings. The size can be set between 1 and
255 characters.
