Functional description
Serves for fixing which TK's are transmitted also without change of the value or sta-
tus.
Set bits cause the transfer of the allocated information types also without change of
the value or status if the information was received with COT<20.
The numbers in the parameter name respond to the basis TK (without time).

Def. 0 0
With the default adjustment (B#16#0) only information with change of value or status
are transferred.
The nodal block offers the possibility for stabilization of measured values using
threshold procedure.
0: without any change of the measurands leads to forwarding.
>0 (e.g. 20): This value is used for direct or mathematical reachable threshold
In each cycle is a check and immediately reaction on direct threshold exceeding
The threshold processing is integrating – in a 1 sec interval the measured value dif-
ference to the last transmission is added up and transmitted spontaneously with the
mathematical achievement of the threshold.
For each measured value individual thresholds can be provided in a parameter data
block if assigned.
The function block is signaling as follows:
Positive values  ok
W#16#0000 ok, no fault
W#16#1000 ok, with reduced cycle (next_Info)
Negative values (16#8xxx)  fault
W#16#8102: P_from_SL_Org = 0
W#16#8103: Shared.Version (Job-ID) = wrong or
pointer wrong positioned
W#16#8112: P_from_Application = 0
W#16#8113: Application.Version (Job-ID) = wrong or
pointer wrong positioned
W#16#8301 IM-DB could not be installed
Reason could be insufficient working memory
W#16#8302 Image-DB full
Info could not be entered anymore
Number of the image-DB created from this block.
Number of the actually entered information in the image-DB.
The update of the image-DB is carried out automatically by incoming spontaneous,
requested or cyclic information.
Indicates that the number of information in the image-DB has been increased within
this OB1-cycle.
