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.

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.
