Class CStoAo
Version 1.0
Modified 08-MAR-2026 11:05:32.00
Code rt_plc_macro_io.h 
 Conditional Storage Analog output.


 Conditional storage of an analog value on a specified
 local Ao-signal (= Ao object).

 Conditional is aimed at the con-input, which is
 supposed to be connected.

 The conditional input signal can be inverted by means
 of the Attribute Editor.

 It is not allowed, by means of a function in C or PLC
 programs, to write in any of the inputs.
RtBody attributes pwr_sClass_cstoao
Float32 In VAL The input is connected to an analog signal or left
open. In the latter case the In value is considered to
be stored.
Boolean Cond con Specifies whether a storage will be done or not. FALSE
means no storage and TRUE means storage of an analog
value.
DevBody attributes 
AttrRef AoObject In Specifies the name of the Ao object where to store the
value.
AttrRef SigChanCon   Used by the PLC Editor.
Int32 AoObjectSegments   Specifies how many segments of the Ao object name that
is to be displayed in the symbol of the CStoAo object.
The segments are counted from behind.
0 and 1 both result in displaying the last segment of
the signal object name.
Boolean ShowSigChanCon   Specifies if the name on the channel object (
associated with the signal object) is to be displayed
in the symbol of the CStoAo object or not. FALSE means
no displaying and TRUE displaying.
See also SigChanConSegments.
Int32 SigChanConSegments   Specifies, when ShowSigChanCon = TRUE, how many
segments of the channel object name that is to be
displayed in the symbol of the CStoAo object. The
segments are counted from behind.
0 and 1 both result in displaying the last segment of
the channel object name.
