Attribute ‘call_after_global_init_slot’¶

Hint

VAR_INPUT declarations in functions or methods that use the attribute lead to compile errors. Reason: Input variables are unknown in this case at the time of the call, which occurs implicitly during the online change.

The effect of this pragma is that all functions and programs containing this attribute are called after the global initialization. You define the order of calling by means of the attribute value.

Syntax:

{attribute 'call_after_global_init_slot' := '<slot>'}

<slot>: Integer value that defines the ranking in the order of the calls; the lower the value, the earlier the call takes place. If several function blocks have the same ranking for the attribute, then the order of their calls remains indefinite.

Insert location: First line above the declaration part of functions and programs

If a method possesses the attribute, CODESYS determines all instances of the corresponding function block and calls all instances in the specified slot. In this case you have no influence on the order of the instances among themselves.
