Functions In ST, you can use a function call as an operand. Example 191 . Example: Result := Fct(7) + 3; TIME() function This function yields the time (in milliseconds) that has elapsed since system b

Data Types In the programming, a variable is identified by its name and memory address in the target system. Variable names are identifiers under which the allocated memory is addressed. The size of t

Data Type: BOOL Type Values Memory BOOL TRUE (1), FALSE (0) 8 bits :

Integer data types Important Information can be lost when converting from larger data types to smaller data types. CODESYS provides the following integer data types. Type Lower limit Upper Limit Memor

Data type: TIME, LTIME The time data type TIME is treated internally as DWORD . In the case of TIME , this leads to a resolution in milliseconds. The time data type LTIME is treated internally as LWOR

Data type: DATE The data types for data and time DATE , DATE_AND_TIME ( DT ), and TIME_OF_DAY ( TOD ) are handled internally as a DWORD (32-bit value). The data types LDATE , LDATE_AND_TIME ( LDT ), a

Data Type: ANY, ANY_ <type> The data types ANY or ANY_ <type> are used in interfaces of functions, function blocks, or methods in order to type input parameters whose type is unknown or unspecified: T

Attribute: enable_dynamic_creation The enable_dynamic_creation pragma is needed for using the __NEW in the case of function blocks. Syntax : {attribute 'enable_dynamic_creation'} Insert location: Firs

Attribute: estimated-stack-usage The pragma provides an estimated value for the stack size requirement. Methods with recursive calls cannot pass a stack check because stack usage cannot be determined.

Attribute: ExpandFully The effect of this pragma is that the members of an array used as an input variable for referenced visualizations are made visible in the properties dialog of the visualization.
