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

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.

Attribute: global_init_slot The pragma defines the order of initialization of POUs and global variable lists: variables within a GVL or a POU are initialized from top to bottom. If there are several g

Attribute: hide Important Using the pragma {attribute 'hide'} to hide variables and POUs does not have the desired effect in most cases. Instead, you should use the {attribute 'conditionalshow'} . pra

Attribute: initialize_on_call The pragma causes input variables of a function block to be initialized on each call of the function block. If an input variable is affected which expects a pointer and t
