5.1.5. Data types supported
The following data types are available for IEC61131-3 programming:
Name Division Format
BOOL Status values: TRUE or FALSE Logical variable.
INT -32768...32767 16-bit integer: Fixed point number without places after the decimal
DINT -2147483648...2147483647 32-bit integer: Fixed point number without places after the decimal
REAL
32-bit floating point: 16 bits before the decimal and 16 bits after the
decimal
WORD 0...65535 16-bit bit sequence (no range of values)
DWORD 0...4294967295 32-bit bit sequence (no range of values)
TIME 0...4194,3035s 32 Bit - Format (resolution: 0.5 ms)
ENUM User-defined type of enumeration (local enumerations are not supported)
Altogether 500 16-bit variables are available. These include BOOL, INT, and
WORD.
Altogether 150 32-bit variables are available. These include
DINT,DWORD,TIME,REAL.
The number of the required variables is displayed in the CoDeSys output window
during compilation.
5.1.6. Retain Variables
6 retain variables (variables that are safe from power failure) are available
 3x16-bit retain-variables
 3x32-bit retain-variables
5.1.7. Recipe table with 9 columns and 32 lines
An array, i.e. a table with 9 columns and 32 rows, is available to store values.
This table is freely assignable and can be used for example to store position sets
or for recipe management.
In addition, this table can be used to exchange data with an external control system
or a POP, for example.
The layout of the table is as follows:
Column 1
Type:
REAL
Objects
O1901
Column 2
Type:
REAL

O1902
Column 3
Type:
INT

In addition to direct access to every individual field in the table, direct access is
also possible through pointer addressing.
To do this, the table pointer "C3ArrayPointer_Row" (Object 1900.1) must be set to
the desired rows.
