User-Defined Function Block [Control]
Overview of Functions
The User-defined function block [control] allows the switching-authority check of a control command and
the check of whether the circuit breaker has reached the position for user-defined controllables.
Function Description
The User-defined function block [control] is located in the folder User-defined functions in the DIGSI 5
Library.
You can instantiate the user-defined function blocks on the top level (in parallel to other function groups) as
well as within function groups and functions.
The task of the function block is to check the switching authority. For control commands, the function block
checks whether the switching direction is the same as the current switch position. You can instantiate every
user-defined signal (for example, SPS, DPC, INC) in the function block and route the corresponding indications
(see following figure).

and Some Individual Indications
Application and Setting Notes
The function block contains the parameters (_:104) Check switching authority, (_:105) Check
if pos. is reached, and (_:150) Check swi.auth. for Mode. The parameter settings Check
switching authority and Check if pos. is reached affect all controllables instantiated in the
function block. Other signal types are not affected by these parameters and objects.
On the other hand, the parameter setting Check swi.auth. for Mode affects the controllable Mode
(controllable) of the function block.
