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).
REAL
Address of a double word floating point value (IEEE format - use the UDINT
type for the BCD, FDIV format).
LREAL
Address of a long word floating point value (IEEE format - use the ULINT
type for the BCD format).
UDINT
Address of an unsigned, double binary word.
UDINT_BCD
Address of an unsigned, double BCD word.
UINT
Address of an unsigned, single binary word.
UINT_BCD
Address of an unsigned, single BCD word
ULINT
Address of an unsigned, quad binary word.
ULINT_BCD
Address of an unsigned, quad BCD word.
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.
The symbol table allows these names to be entered and edited directly. Each symbol name
must be unique. Use the following procedure to activate the symbol tables.
1, 2, 3…
1. Double-click on the symbol table object beneath the PLC in the project workspace. The
global (i.e. PLC’s) symbol table is displayed containing global symbols.
