UC

Unconditioned Call

Syntax:        UC        FBxx        

 UC        FCxx

The specified block is called independent of the RLO. No parameter list appears.

You should use this kind of call only for functions and function blocks that do have neither parameter nor static variables, otherwise unexpected results occur, your program will definitely be difficult to understand.

If you do not specify an IDB calling a FB the IDB will be used instead of the calling block! This usually leads to silly results.
